1. Overview and Purpose
This document provides a comprehensive review of twelve transport data platforms and databases that are relevant to the design and construction of a Global Intelligence System for Transport. Each platform is assessed across six dimensions:
- What it is and who operates it
- Data content -- what datasets and indicators are available
- Geographic coverage -- global, regional, or country-specific
- Data access -- APIs, bulk downloads, web interfaces, licensing
- Status -- active, in development, dormant, or archived
- Relevance -- how the platform could contribute to a unified global transport intelligence system
The platforms span the full spectrum from spatial/geospatial infrastructure data (OPSIS, African Transport Systems Database) to statistical observatories (ITF, ATO, UNECE TDC) to real-time monitoring (PortWatch) to research programmes that generate data as a by-product (HVT, RECAP).

5. TDCI – Transport Data Collection Instruments
What It Is
The Transport Data Collection Instruments (TDCI) are a set of standardised survey templates and methodologies developed under the Sub-Saharan Africa Transport Policy Program (SSATP), which is housed at the World Bank. The TDCI were designed to help African countries collect comparable, consistent transport sector data, covering roads, rail, ports, airports, inland waterways, and urban transport.
- Operator: SSATP / World Bank
- Origin: Developed in the early 2000s, updated periodically
- URL: Available through SSATP website (https://www.ssatp.org/)
Data Content
The TDCI are instruments (i.e., survey forms and methodologies), not a database per se. They define what data should be collected:
- Road sub-sector: Network length by classification, condition (IRI), traffic counts, road safety statistics, expenditure
- Rail sub-sector: Track length, rolling stock, freight/passenger volumes, operational statistics
- Maritime/port sub-sector: Port throughput (TEUs, tonnage), vessel calls, dwell times
- Aviation sub-sector: Passenger and cargo volumes, fleet data, airport capacity
- Inland waterways: Network length, vessel counts, cargo volumes
- Urban transport: Fleet size, route coverage, ridership, fare data
- Cross-cutting: Institutional data, financing, policy indicators
Geographic Coverage
- Sub-Saharan Africa primarily, though the methodology could be applied elsewhere
- Designed for use by national transport ministries and statistical agencies
Data Access
- Instrument documents: Available as PDFs/Word documents through SSATP
- Collected data: Held by individual countries; some aggregated through SSATP reports or the Africa Transport Observatory
- No centralised database of TDCI-collected data exists publicly (this is a key gap)
Current Status
Legacy instruments, partially superseded. The TDCI concept has been folded into the broader Africa Transport Observatory (ATO) initiative, which aims to create a centralised platform for the data that TDCI instruments were designed to collect.
Relevance to Global Transport Intelligence
The TDCI are relevant not as a data source but as a methodological template:
- They demonstrate what a standardised transport data collection framework looks like
- They identify the key indicators needed for transport sector monitoring
- The indicator set could inform the schema design of a global transport intelligence system
- Their adoption challenges (incomplete rollout, inconsistent use) provide lessons for any global data harmonisation effort
6. HVT – High Volume Transport Programme
What It Is
The High Volume Transport (HVT) Applied Research Programme was a FCDO-funded (UK Foreign, Commonwealth & Development Office) research programme focused on improving transport in low- and middle-income countries. It concentrated on "high volume" corridors -- major roads, railways, and urban transport systems that carry the bulk of passenger and freight traffic.
- Operator: FCDO, managed by IMC Worldwide (now DT Global)
- URL: https://transport-links.com/hvt/ (archived)
- Duration: 2017--2023
- Budget: Approximately GBP 17.5 million
Data Content
HVT produced research outputs rather than operational databases, including:
- Road safety research: Crash data analysis, road safety audit methodologies, star rating data
- Climate resilience: Vulnerability assessments for transport corridors, climate adaptation case studies
- Urban transport: Bus system performance data, informal transport surveys, mobility data analysis
- Gender and inclusion: Transport accessibility studies, gender-disaggregated travel data
- Asset management: Road condition data, maintenance decision support tools
- Economic analysis: Transport cost studies, economic appraisal methodologies
Geographic Coverage
- Global focus on LMICs: Research conducted in countries across Africa, South Asia, and Southeast Asia
- Key country studies in Kenya, Tanzania, Ghana, Nepal, Bangladesh, Myanmar, and others
Data Access
- Reports and tools: Published on transport-links.com and through academic journals
- Datasets: Some research datasets deposited in the UK Data Archive or published as supplementary materials
- Tools: Several software tools developed (e.g., road safety tools, climate vulnerability tools)
- License: Generally open access for research outputs
Current Status
Completed (2023). The programme has ended, but outputs remain available through the transport-links.com archive and academic publications. Some tools continue to be used by partner organisations.
Relevance to Global Transport Intelligence
HVT's value lies in its research methodologies and datasets for LMICs:
- Road safety analysis frameworks applicable to countries with limited data
- Climate vulnerability assessment methods for transport infrastructure
- Urban transport data collection methodologies (particularly for informal transport)
- Evidence base for transport investment decisions in data-poor environments
7. RECAP – Research for Community Access Partnership
What It Is
The Research for Community Access Partnership (ReCAP) was a FCDO-funded research programme focused on rural and low-volume road access in low-income countries. It was the counterpart to HVT, addressing the "last mile" connectivity challenge rather than high-volume corridors.
- Operator: FCDO, managed by Cardno (now DT Global)
- URL: https://transport-links.com/recap/ (archived)
- Duration: 2014--2023
- Budget: Approximately GBP 16 million
- Predecessor programmes: AFCAP (Africa Community Access Partnership), ASCAP (Asia Community Access Partnership)
Data Content
- Rural road inventories: Condition surveys, traffic counts on low-volume roads
- Rural Access Index (RAI): Methodological work on measuring the proportion of rural populations within 2 km of an all-season road -- a key SDG indicator (SDG 9.1.1)
- Rural transport services: Studies of intermediate means of transport, motorcycle taxis, boat transport
- Materials research: Local materials for road construction (e.g., marginal materials, recycled materials)
- Bridge/river crossing inventories: Data on rural connectivity gaps
- Climate vulnerability: Climate impact assessments on rural roads
Geographic Coverage
- Sub-Saharan Africa: Through AFCAP -- Ethiopia, Kenya, Tanzania, Uganda, Mozambique, Ghana, Sierra Leone, DRC, South Sudan, and others

Data Access
- Reports: Published on transport-links.com
- RAI data: Some Rural Access Index data feeds into World Bank and UN statistics
- Research datasets: Selectively available through UK Data Archive
- Tools: Rural road investment prioritisation tools
Current Status
Completed (2023). Like HVT, the programme has concluded but outputs remain accessible. The Rural Access Index methodology continues to be used by the World Bank and UN for SDG monitoring.
Relevance to Global Transport Intelligence
RECAP is critical for the rural accessibility dimension of a global transport system:
- The RAI methodology is the basis for SDG indicator 9.1.1 and is directly relevant to measuring transport access
- Rural road condition and inventory data fills gaps not covered by major geospatial databases
- Methodologies for data collection in extremely data-poor environments
- Evidence on transport services (not just infrastructure) in rural areas
8. ATO – Africa Transport Observatory
What It Is
The Africa Transport Observatory (ATO) is a continental transport data platform being developed under the auspices of the African Union Commission (AUC) with support from the SSATP (World Bank) and other partners. It aims to be the central repository for transport statistics across all 54 African Union member states, covering all transport modes.

Current Status
In development / partially operational. The ATO has been under development for several years. Some country data and corridor monitoring data is available, but coverage remains incomplete. Data quality and timeliness vary significantly. The platform depends on voluntary data submission by national agencies.
Relevance to Global Transport Intelligence
The ATO is the most ambitious continental transport data initiative for Africa:
- If successful, it would provide standardised transport statistics for the entire continent
- Corridor monitoring data is uniquely valuable for trade facilitation analysis
- The platform's challenges (data gaps, institutional capacity, sustainability) are instructive for any global-scale effort
- A global transport intelligence system should integrate with ATO rather than duplicate its coverage for Africa
9. ITF – International Transport Forum (OECD)

- Project-level data provides ground truth on infrastructure investments
- RAI data is the key rural accessibility metric
- Integration via the Open Data API would be straightforward
11. UNECE Transport Data Commons
Full details: UNECE Transport Data Commons Profile
What It Is
The UNECE Transport Data Commons (TDC) is an emerging initiative by the United Nations Economic Commission for Europe (UNECE) Inland Transport Committee to create a shared, interoperable platform for transport data. It aims to go beyond traditional statistical databases by establishing common data standards, ontologies, and exchange protocols that would allow disparate transport data systems to interoperate.
- Operator: UNECE Inland Transport Committee (ITC)
- URL: https://unece.org/transport (general); TDC materials distributed through ITC working groups
- Governance: UNECE Working Party on Transport Statistics (WP.6) and related expert groups
Data Content
The TDC concept encompasses:
- Statistical data: Traditional transport statistics (freight, passenger, infrastructure, safety) already collected by UNECE through annual questionnaires
- Geospatial data: Transport network data with geographic references
- Real-time data: Aspirational -- integration of real-time traffic and logistics data
- Metadata standards: Common definitions, classifications, and quality frameworks
- Data exchange protocols: Standardised formats for data sharing between national and international systems
Existing UNECE transport statistics include:
- Annual road, rail, inland waterway, and pipeline statistics for 56 UNECE member states
- Road traffic accident statistics
- Census of Motor Traffic on Main International Traffic Arteries (E-road census)
- Transport of Dangerous Goods statistics
- Vehicle type approval data
Geographic Coverage
- 56 UNECE member states: Europe, Central Asia, North America (US, Canada)
- The TDC aspiration is to develop standards that could be adopted globally
Data Access

- Formats: PX (PC-Axis), CSV, Excel for current statistics
- Aspirational: SDMX, linked data, API access for the TDC
Current Status
In development. The TDC is a strategic initiative that has been discussed at UNECE ITC sessions since approximately 2020-2021. Conceptual frameworks and pilot activities exist, but a fully operational "data commons" platform is not yet available. The initiative is progressing through working group discussions and pilot projects.
Relevance to Global Transport Intelligence
The UNECE TDC is perhaps the most conceptually aligned initiative with a global transport intelligence system:
- It directly addresses data interoperability and standardisation
- The standards and ontologies being developed could form the backbone of a global system
- UNECE's convening power means standards have a path to adoption
- Existing UNECE statistics provide a solid foundation for European and Central Asian coverage
- Gap: the TDC is still early-stage and may take years to fully materialise
12. ADB Transport Outlook – Asian Development Bank
What It Is

- Provides a single, harmonised, quality-controlled geospatial dataset for the entire continent
- Peer-reviewed methodology ensures data quality documentation
- Open license enables unrestricted use
- Could serve as the baseline Africa layer in a global transport system
- Complements OPSIS (which has global coverage but may differ in African detail)
- Limitation: static snapshot requires periodic updating
14. Transport Atlas (UN Resolution 2C Context)
What It Is
The Transport Atlas concept emerges from discussions around UN General Assembly Resolution 78/2C (and related resolutions) on sustainable transport, which called for improved global transport data and analytics. The idea is to create a comprehensive, UN-backed atlas of global transport systems that would support monitoring of transport-related SDGs and inform policy decisions.
- Context: UN General Assembly resolutions on sustainable transport
- Lead agencies: UN DESA, UNECE, regional commissions, potentially UN-Habitat for urban transport
- Status: Conceptual / early planning stage
Data Content (Aspirational)
The Transport Atlas concept envisions:
- Global transport network maps: Comprehensive geospatial data on all modes
- Transport performance indicators: Standardised metrics across countries
- SDG monitoring data: Particularly SDG 9.1.1 (Rural Access Index), SDG 11.2 (public transport access), SDG 3.6 (road safety)
- Climate and transport: Emissions data and climate vulnerability assessments
- Transport connectivity indices: Measures of how well countries and regions are connected
Geographic Coverage
- Global -- all UN member states (aspirational)
Data Access
- Not yet available as a platform
- Would likely build on existing UN data systems (UNECE statistics, UN SDG databases, regional commission data)
Current Status
Proposed / conceptual. The Transport Atlas does not yet exist as an operational platform. It is a policy aspiration that has been discussed in UN forums. Its realisation depends on political commitment, funding, and institutional coordination among UN agencies.
Relevance to Global Transport Intelligence
The Transport Atlas represents the political and institutional aspiration that a global transport intelligence system could help realise:
- It signals demand from the international community for better global transport data
- A bottom-up technical effort (building a global transport intelligence system) could provide the data infrastructure that a top-down policy initiative (Transport Atlas) needs
- Aligning with the Transport Atlas concept could provide political support and institutional buy-in for a technical platform
15. SUM4ALL Global Tracking Framework
What It Is
The Global Tracking Framework for Transport (GTF) is the first-ever global repository of transport data and indicators, maintained by the Sustainable Mobility for All (SuM4All) partnership — a consortium of 55+ international transport organisations convened by the World Bank. It provides 60+ indicators across 183 countries, organised around four policy goals (Universal Access, Efficiency, Safety, Green Mobility), and produces the Global Sustainable Mobility Index (GSMI) — a composite score for cross-country benchmarking.
- URL: https://sum4all.org/global-tracking-framework
- Online tool: https://sum4all.org/online-tool (Policy Decision-Making Tool 3.0)
- World Bank portal: https://datatopics.worldbank.org/sum4all/

- Most underlying indicators accessible via upstream APIs already documented in the Data Access Audit
- Indicator-to-source mapping: GTF Sources PDF
Current Status
Active. GTF 3.0 published in 2022 with 16 new indicators added. Regularly updated with new data. GSMI covers 183 countries (up from fewer in earlier versions).
Relevance to Global Transport Intelligence
The GTF is uniquely valuable as a framework and benchmarking tool:
- Provides a ready-made taxonomy (4 goals) for organising transport indicators
- GSMI enables cross-country comparison that no other source offers
- Its indicator selection serves as a curated "what matters" list for transport policy
- Identifies several upstream sources not yet in our audit (UNCTAD, IEA, WEF, ITDP)
- The 4-goal structure could inform how we organise data in the intelligence system
- Limitation: no programmatic access — replication from upstream APIs is the preferred integration path

17. Recommendations for a Global Transport Intelligence System
Tier 1: Core Data Sources (integrate first)
- OPSIS / open-gira -- Use as the foundational geospatial layer for transport networks globally. Leverage the open-source analysis codebase.
- PortWatch -- Integrate as the maritime monitoring layer, providing real-time port activity and trade flow data.
- World Bank Open Data -- Use the API to ingest key transport indicators (WDI, LPI, RAI) for all countries.
- ITF Statistics -- Integrate via SDMX API for high-quality time-series data for OECD+ countries.
Tier 2: Regional Enrichment (add for depth)
-
African Transport Systems Database -- Use as the detailed Africa layer, complementing OPSIS.
-
ADB Key Indicators -- Fill Asia-Pacific gaps in ITF coverage.
-
ATO -- Monitor and integrate as the platform matures; valuable for African corridor data.
-
UNECE Statistics -- Use existing statistics for Europe/Central Asia; watch TDC development.
-
SUM4ALL GTF -- Adopt the 4-goal taxonomy and GSMI methodology; replicate from upstream APIs rather than scraping. Use as the reference framework for indicator selection and country benchmarking.
Tier 3: Methodological and Conceptual (inform design)
- TDCI -- Use indicator framework to inform the global system's schema design.
- HVT / RECAP -- Draw on research datasets and methodologies, particularly for data-poor environments and rural access.
- Transport Atlas -- Align with the UN vision to build institutional support.
- UNECE TDC -- Adopt emerging standards and ontologies as they are published.
Key Gaps to Address
- Real-time road transport data: No platform provides global real-time road traffic data (PortWatch does this for maritime)
- Urban transport / public transit: Weak coverage across all platforms; consider GTFS aggregators (e.g., Transitland, OpenMobilityData)
- Freight logistics (overland): Limited data on trucking, warehousing, last-mile delivery
- Transport services (vs. infrastructure): Most platforms focus on physical assets; service frequency, reliability, and cost data is scarce
- Pacific Islands, Caribbean, Central Asia: Systematic coverage gaps across most platforms
This document serves as a foundation for designing data integration strategies for a Global Transport Intelligence System. Each platform profile should be validated against current platform URLs and documentation before integration work begins.
OPSIS -- Open Platform for Systemic Infrastructure Spatial Analysis
Platform URL: https://global.infrastructureresilience.org/ Operator: University of Oxford / GFDRR / World Bank Code Repository: https://github.com/nismod Last reviewed: 2026-02-09
1. Overview
OPSIS (Open Platform for Systemic Infrastructure Spatial analysis) is an open-access geospatial platform that enables the visualisation and analysis of global infrastructure networks and their vulnerability to natural hazards and climate change. The platform is a central output of the Global Infrastructure Resilience Initiative (GIRI), a partnership between the University of Oxford's infrastructure research groups and the World Bank's Global Facility for Disaster Reduction and Recovery (GFDRR).
The platform name "OPSIS" has been used to describe the suite of tools and data at global.infrastructureresilience.org. It builds on years of research at Oxford under the National Infrastructure Systems Model (nismod) programme and the Infrastructure Transitions Research Consortium (ITRC).
Key Organisations
| Organisation | Role |
|---|---|
| University of Oxford (School of Geography & Environment, Environmental Change Institute) | Research, methodology, software development |
| GFDRR (Global Facility for Disaster Reduction and Recovery, World Bank) | Funding, institutional support, policy engagement |
| World Bank | Institutional host for GFDRR, data consumer |
| UNDRR | Disaster risk reduction policy alignment |
| Various national partners | Country-level data provision and validation |
2. Data Content
2.1 Transport Infrastructure Networks
The transport data layer is one of the most complete components of the platform:
Roads:
- Global road network derived from OpenStreetMap and supplemented with government data where available
- Classification: motorway, trunk, primary, secondary, tertiary, residential/local
- Attributes include: surface type (paved/unpaved where data exists), number of lanes (where mapped), bridge/tunnel identification
- Quality varies by region -- excellent in Europe, North America, East Asia; variable in Sub-Saharan Africa, Central Asia
Railways:
- Global rail network including main lines and branch lines
- Attributes: gauge, electrification status, operational status
- Derived primarily from OpenStreetMap with supplementary sources
Ports:
- Major port locations globally
- Linked to trade flow data where available
- Port area/boundary polygons for hazard exposure analysis
Airports:
- Airport locations (from OurAirports and OpenStreetMap)
- Runway data, airport classification (international, domestic, military)
Inland Waterways:
- Navigable waterway network (coverage varies significantly by region)
2.2 Other Infrastructure Sectors
- Energy: Power plants (type, capacity, fuel), transmission lines, substations, off-grid solar
- Water: Dams, water treatment plants, distribution networks
- Telecommunications: Cell towers, submarine cables, fibre networks
2.3 Hazard Layers
- Flood: Fluvial (river), pluvial (surface water), and coastal flood maps at multiple return periods (e.g., 1-in-10, 1-in-100, 1-in-1000 year)
- Tropical cyclones: Wind speed maps at multiple return periods
- Earthquake: Seismic hazard maps (peak ground acceleration)
- Landslide: Susceptibility maps
- Drought: Drought hazard indicators
- Climate change scenarios: Hazard projections under RCP/SSP scenarios
2.4 Analytical Outputs
- Exposure analysis: Which infrastructure assets are located in hazard zones
- Expected Annual Damage (EAD): Modelled damage costs integrating hazard probability and asset vulnerability
- Criticality analysis: Network analysis identifying which assets, if disrupted, would have the largest impact on service delivery (e.g., which road segments carry the most traffic, which bridges, if destroyed, would cause the longest detours)
- Adaptation analysis: Cost-benefit analysis of climate adaptation measures for infrastructure
3. Geographic Coverage
| Region | Road Coverage | Rail Coverage | Port Coverage | Hazard Coverage |
|---|---|---|---|---|
| Europe | Excellent | Excellent | Good | Good |
| North America | Excellent | Good | Good | Good |
| East Asia | Good | Good | Good | Good |
| South Asia | Good | Moderate | Good | Good |
| Southeast Asia | Good | Moderate | Good | Good |
| Sub-Saharan Africa | Moderate | Moderate | Good | Good |
| Central Asia | Moderate | Moderate | Limited | Good |
| Middle East / N. Africa | Moderate | Moderate | Good | Good |
| Latin America | Good | Moderate | Good | Good |
| Pacific Islands | Limited | N/A | Moderate | Good |
Coverage quality is primarily driven by OpenStreetMap completeness for transport networks, and by global hazard modelling availability for hazard layers.
4. Technical Architecture
4.1 Software Stack
The platform is built on an open-source technology stack:
- Backend analysis: Python (NetworkX, GeoPandas, Rasterio, Snail)
- Geospatial processing: PostGIS, GDAL/OGR
- Web frontend: React-based web application with Mapbox GL JS for map rendering
- Tiling: Vector tiles served via standard protocols
- Data storage: Combination of GeoPackage files, GeoTIFFs, and PostgreSQL/PostGIS databases

- The platform itself is free to access and use
6. Strengths and Limitations
Strengths
- Global scope with consistent methodology across countries
- Multi-hazard analysis covering all major natural hazards
- Network-level analysis goes beyond asset-level exposure to assess systemic risk
- Open source -- all analysis code is publicly available and reproducible
- Active development with growing country coverage and analytical capabilities
- Strong institutional backing (World Bank, Oxford) ensures continuity
Limitations
- Static analysis -- no real-time monitoring or updating; analyses reflect a snapshot in time
- OSM dependency -- transport network quality mirrors OpenStreetMap completeness, which is uneven globally
- No formal API -- programmatic access requires working with the codebase directly
- Limited attribute data -- network geometries are well-covered, but traffic volumes, condition data, and operational characteristics are mostly absent
- Modelled rather than observed -- damage and disruption estimates are based on models and assumptions, not observed events
7. Integration Strategy for Global Transport Intelligence
What to Use
- Transport network geometries -- Use as the base spatial layer for road, rail, port, and airport networks globally
- Hazard exposure data -- Pre-computed exposure analysis for climate resilience assessments
- Criticality metrics -- Network analysis results identifying the most important infrastructure assets
- Analysis pipelines -- Adapt the
open-giraandsnailcodebases for custom analysis
How to Integrate
- Data ingestion: Download GeoPackage files from data repositories; parse using GeoPandas/GDAL
- Network model: Use the processed network topologies as the backbone for routing and connectivity analysis
- Hazard overlay: Combine with PortWatch maritime data for a multi-modal resilience view
- Update mechanism: Periodically re-run data pipelines against updated OSM extracts and hazard models
- Attribution: Link network segments to ITF/WB/UNECE statistics for traffic volume enrichment
Key Contacts / Entry Points
- The OPSIS/GIRI team is reachable through the University of Oxford's Environmental Change Institute
- GFDRR at the World Bank coordinates the institutional partnership
- GitHub issues on the
nismodrepositories are monitored by the development team
This profile should be validated against the current state of global.infrastructureresilience.org and the nismod GitHub organisation.
PortWatch / OxMarTrans -- IMF Maritime Transport Monitoring
Platform URL: https://portwatch.imf.org/ Operator: IMF Research Department & University of Oxford Last reviewed: 2026-02-09
1. Overview
PortWatch is a real-time global maritime trade monitoring platform developed jointly by the International Monetary Fund (IMF) and the Oxford Martin Programme on the Future of Trade (OxMarTrans) at the University of Oxford. The platform uses Automatic Identification System (AIS) vessel tracking data to monitor port activity, detect trade disruptions, and estimate the economic impact of supply chain shocks.
PortWatch was created in response to the COVID-19 pandemic's disruption of global trade and has since evolved into a standing capability for monitoring maritime supply chains. It represents one of the most advanced applications of "big data" (AIS vessel movements) to macroeconomic analysis.
Key Organisations
| Organisation | Role |
|---|---|
| IMF Research Department | Economic analysis, platform hosting, institutional authority |
| Oxford Martin School (OxMarTrans programme) | AIS data processing, trade flow estimation, academic research |
| MarineTraffic / Spire / other AIS providers | Raw AIS vessel tracking data |
| UN COMTRADE | Baseline trade statistics for calibration |
2. Data Content
2.1 Port Activity Data

- Port throughput estimates: Estimated cargo volumes based on vessel size, type, and port calls
- Turnaround time: Average time vessels spend in port (from arrival to departure)
- Waiting time: Time vessels spend at anchorage before berthing
- Historical time series: Port activity data going back several years, enabling trend analysis and anomaly detection
2.2 Disruption Detection
- Automated alerts: Algorithmic detection of abnormal drops in port activity (e.g., sudden decline in vessel calls)
- Disruption events: Catalogued events linking port disruptions to causes (natural disaster, geopolitical event, strike, etc.)
- Recovery tracking: Monitoring how quickly port activity returns to baseline after disruption
2.3 Trade Flow Estimates
- Bilateral trade flows: Estimated maritime trade volumes between country pairs, based on vessel movements and port-to-port connections
- Commodity-level estimates: Disaggregation by broad commodity categories (containers, dry bulk, liquid bulk, etc.)
- Trade network analysis: Identification of key maritime trade routes and dependencies
2.4 Climate and Hazard Exposure
- Cyclone tracking: Real-time tropical cyclone tracks overlaid on port locations
- Flood exposure: Coastal and riverine flood risk for port areas
- Sea level rise: Long-term exposure projections for port infrastructure
- Historical events: Database of past climate-related port disruptions
2.5 Economic Impact Modelling

- Trade impact estimates: Estimated changes in bilateral trade volumes due to disruptions
- Vulnerability indices: Country-level measures of economic vulnerability to maritime trade disruptions
3. Geographic Coverage
3.1 Port Coverage
- 1,300+ ports globally monitored (the exact number continues to grow)
- Coverage includes all major commercial ports worldwide
- Smaller ports, fishing ports, and military ports may have limited coverage
3.2 Regional Breakdown
| Region | Ports Covered | Coverage Quality |
|---|---|---|
| East Asia | 250+ | Excellent |

- Port-centric -- data is aggregated to port level; detailed vessel-level data is not exposed
- No open-source code -- unlike OPSIS, the analysis pipeline is not publicly available
- IMF access terms -- while free for research, commercial use terms may be restrictive
8. Integration Strategy for Global Transport Intelligence
What to Use
- Port activity data -- Real-time and historical vessel calls, throughput, turnaround times as a maritime transport monitoring layer
- Disruption alerts -- Automated notifications for supply chain early warning systems
- Trade flow estimates -- Maritime bilateral trade data to complement overland freight statistics
- Climate exposure -- Port-level hazard data for resilience assessments
How to Integrate
- API integration: Connect to PortWatch API for automated data ingestion
- Poll for updated port activity data (e.g., daily or weekly)
- Subscribe to disruption alerts for real-time notifications
- Port-network linking: Match PortWatch port identifiers to OPSIS port geometries and to land-side transport networks
- Trade-transport correlation: Link maritime trade flows to overland corridors (e.g., a surge in port activity in Mombasa implies increased freight on the Northern Corridor)
- Dashboard integration: Embed PortWatch visualisations or reformat data for a unified transport dashboard
- Economic overlay: Use GDP impact estimates to prioritise transport corridors by economic significance
Complementary Platforms
- OPSIS: Provides the port-to-hinterland transport network that PortWatch lacks
- ITF: Provides freight statistics by mode to contextualise maritime data
- ATO: Provides African corridor monitoring to link with port activity
- World Bank LPI: Provides logistics performance context for PortWatch port data
This profile should be validated against the current PortWatch API documentation and terms of use at portwatch.imf.org.
UNECE Transport Data Commons (TDC)
Parent Organisation URL: https://unece.org/transport Statistics Portal: https://w3.unece.org/PXWeb/en Operator: UNECE Inland Transport Committee Last reviewed: 2026-02-09
1. Overview
The UNECE Transport Data Commons (TDC) is a strategic initiative by the United Nations Economic Commission for Europe (UNECE) to modernise and interconnect transport data systems globally. Unlike a traditional database, the TDC is conceived as a data ecosystem -- a set of shared standards, protocols, and infrastructure that would allow national statistical offices, international organisations, and private-sector data holders to share and combine transport data in interoperable ways.
The initiative sits within the UNECE Inland Transport Committee (ITC), the principal UN body for inland transport conventions and agreements in the UNECE region. It is driven by the recognition that transport data is fragmented across modes, jurisdictions, and institutions, and that the transition to sustainable, digitalised transport systems requires fundamentally new approaches to data sharing.
Institutional Context
| Body | Role |
|---|---|
| UNECE Inland Transport Committee (ITC) | Governing body; sets strategic direction |
| Working Party on Transport Statistics (WP.6) | Technical coordination of transport statistics |
| Working Party on Transport Trends and Economics (WP.5) | Economic and policy analysis |
| Group of Experts on Transport Data Commons | Dedicated expert group developing the TDC concept |
| UNECE Statistics Division | Data collection, processing, and dissemination |
2. Existing UNECE Transport Statistics
Before discussing the TDC initiative, it is important to understand the existing UNECE transport statistics programme, which the TDC aims to transform and extend.
2.1 Annual Questionnaire Data
UNECE collects transport data annually from its 56 member states through standardised questionnaires. Key datasets include:
Road Transport:
- Road network length by type (motorway, national, regional, etc.)
- Vehicle fleet by type (passenger cars, buses, goods vehicles, etc.)
- New vehicle registrations
- Road freight (tonne-km) and passenger (passenger-km) transport
- Road traffic accidents, injuries, and fatalities
- Road infrastructure investment and maintenance expenditure
Rail Transport:
- Rail network length (electrified/non-electrified, gauge)
- Rolling stock (locomotives, passenger coaches, freight wagons)
- Rail freight (tonne-km) and passenger (passenger-km) transport
- Rail safety statistics
Inland Waterway Transport:
- Waterway network length
- Vessel fleet
- Freight volumes (tonne-km)
Pipeline Transport:
- Oil and gas pipeline statistics
Combined/Intermodal Transport:
- Intermodal transport units (TEUs, swap bodies) statistics
2.2 E-Road Census
The Census of Motor Traffic on Main International Traffic Arteries (E-road census) provides traffic volume data (AADT -- Annual Average Daily Traffic) on the European E-road network. This census is conducted approximately every 5 years.
2.3 Transport of Dangerous Goods
Statistics on the transport of dangerous goods by road, rail, and inland waterway.
2.4 Glossary for Transport Statistics
The UNECE/ITF/Eurostat Glossary for Transport Statistics provides standardised definitions for transport statistical terms. This is a critical reference for any data harmonisation effort.
3. The Transport Data Commons Initiative
3.1 Concept and Vision
The TDC initiative goes beyond traditional statistics to envision a connected data ecosystem with the following characteristics:
- Interoperability: Transport data from different sources (national statistics, sensors, private sector) should be combinable using shared standards
- Multi-modal: Breaking down silos between road, rail, maritime, air, and urban transport data
- Multi-scale: From local/urban to national to international to global
- Dynamic: Moving beyond annual statistics to more frequent, potentially real-time data
- FAIR principles: Data should be Findable, Accessible, Interoperable, and Reusable
- Inclusive: Developing country participation and capacity building
3.2 Key Components (Proposed)
| Component | Description | Status |
|---|---|---|
| Common data model / ontology | Shared vocabulary and data structure for transport data | Under development |
| Metadata standards | Standardised descriptions of datasets enabling discovery | Building on existing SDMX/DDI |
| Data exchange protocols | Technical standards for data sharing between systems | Conceptual |
| Quality framework | Common approach to data quality assessment | Building on UN quality frameworks |
| Reference datasets | Shared foundational datasets (e.g., transport network geometries, port/airport codes) | Partial (existing UNECE data) |
| Governance framework | Rules for data sharing, access, attribution | Under discussion |
| Capacity building | Training and tools for countries to participate | Planned |
3.3 Relationship to Other Initiatives
The TDC does not exist in isolation. It connects to several broader data initiatives:
- UN Global Platform: The UN's cloud-based platform for big data and data science, which could host TDC infrastructure
- SDMX (Statistical Data and Metadata eXchange): The standard already used by OECD/ITF and Eurostat; TDC should extend rather than replace it
- Linked Open Data: The TDC may adopt semantic web / linked data approaches for data interoperability
- EU Mobility Data Space: The European Union's initiative for sharing mobility data across member states; the TDC and EU MDS should be interoperable
- MaaS (Mobility as a Service) data standards: NeTEx, SIRI, GTFS, and other transit data standards that the TDC could incorporate
4. Geographic Coverage
4.1 Current Statistics Coverage
The 56 UNECE member states span:
- Europe: All European countries including EU, EFTA, Western Balkans, Eastern Europe
- Central Asia: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan
- Caucasus: Armenia, Azerbaijan, Georgia
- North America: Canada, United States
- Israel, Turkey
4.2 Aspirational TDC Coverage
The TDC aims to develop standards and protocols that could be adopted globally, beyond the UNECE region. Collaboration with other UN regional commissions (ECA, ESCAP, ECLAC, ESCWA) could extend coverage to their member states.
5. Data Access
5.1 Current Access Methods
| Method | URL | Notes |
|---|---|---|
| PXWeb statistical database | w3.unece.org/PXWeb/en | Interactive query tool; data in PX format, CSV, Excel |
| UNECE Statistical Publications | unece.org/statistics | Annual bulletin, transport statistics for Europe and North America |
| PDF/Excel reports | Various | Published analyses and country profiles |
| Glossary | Published as PDF and online | Reference for definitions |
5.2 Planned TDC Access (Aspirational)
- API (SDMX-based): Machine-readable access to statistical data
- Linked data endpoints: SPARQL or similar for semantic queries
- Data catalogue: Searchable metadata registry of transport datasets
- Data download portal: Improved bulk download capabilities
- Interoperability layer: Protocols for connecting to national data systems
6. Technical Standards and Classifications
UNECE maintains or co-maintains several key transport classifications:
| Standard | Description |
|---|---|
| CEVNI | European Code for Inland Waterways |
| ADR | European Agreement concerning the International Carriage of Dangerous Goods by Road |
| COTIF/RID | Regulations concerning the International Carriage of Dangerous Goods by Rail |
| Vehicle type approval (1958 Agreement) | Harmonised vehicle technical standards |
| Digital tachograph | Standards for recording driving/rest times |
| TIR Convention | International road transport customs transit system |
| CMR | Convention on the Contract for the International Carriage of Goods by Road |
| E-road network classification | Standardised designation of main international traffic arteries |
These conventions and standards are globally significant and form part of the regulatory infrastructure that a transport data commons would need to reference.
7. Strengths and Limitations
Strengths
- Institutional authority: UNECE is the UN body with the legal mandate for inland transport conventions; standards it develops have a clear path to adoption
- Long time series: Annual statistical data going back decades for many indicators
- Standardised definitions: The UNECE/ITF/Eurostat Glossary is the authoritative reference for transport statistics terminology
- Convention framework: The transport conventions (TIR, ADR, CMR, etc.) provide a legal and operational context that pure data platforms lack
- Global ambition: The TDC is explicitly designed to be scalable beyond the UNECE region
Limitations
- Early stage: The TDC is still largely conceptual; no operational platform exists yet
- Slow pace: UN processes are consensus-driven and slow; the TDC may take many years to materialise
- Limited to inland transport: Maritime and aviation are largely outside UNECE ITC's mandate (IMO and ICAO respectively)
- Annual frequency: Current statistics are annual, with 1-2 year publication lags
- European focus: Despite 56 member states, the strongest data coverage is for European countries
- No geospatial data: Current statistics are tabular (national aggregates), not spatially referenced
8. Integration Strategy for Global Transport Intelligence
What to Use Now
- Existing statistics: Ingest current UNECE transport statistics (via PXWeb or bulk download) for European and Central Asian transport indicators
- Glossary: Adopt the UNECE/ITF/Eurostat Glossary as the basis for the global system's data dictionary
- Classifications: Use UNECE transport classifications (E-road network, vehicle types, etc.) as reference standards
- E-road census data: Traffic volume data for the European road network
What to Watch
- TDC development: Monitor the ITC working groups for progress on data standards and protocols
- Common data model: When published, evaluate the TDC data model/ontology for adoption
- API development: When available, integrate with the TDC API
- EU Mobility Data Space: Watch for convergence or divergence with the EU initiative
How to Contribute
A global transport intelligence system could contribute to the TDC rather than just consume from it:
- Share methodologies for data harmonisation developed during the global system's construction
- Provide test cases for TDC standards (e.g., "here is how African transport data maps to the TDC data model")
- Contribute open-source tools for data transformation and quality assessment
- Participate in UNECE working group discussions to ensure TDC standards meet global needs
Complementary Platforms
- ITF: The OECD's ITF uses SDMX and covers similar (but not identical) countries; coordinate to avoid duplication
- Eurostat: Covers EU member states with more granular data; should be interoperable with TDC
- OPSIS: Provides the geospatial infrastructure data that UNECE statistics lack
- PortWatch: Covers maritime trade data outside UNECE ITC's inland transport mandate
This profile should be validated against current UNECE ITC session documents and the latest TDC working group outputs.
The African Transport Systems Database
Publication: Scientific Data (Nature Publishing Group) Data Repository: Zenodo / figshare (open access) Operator: Academic research team Last reviewed: 2026-02-09
1. Overview
The African Transport Systems Database is a comprehensive, harmonised geospatial database of transport infrastructure across all 54 African countries, published as a peer-reviewed data descriptor in the journal Scientific Data (part of the Nature portfolio). It represents one of the most systematic efforts to compile, clean, harmonise, and validate continent-wide transport infrastructure data from multiple sources.
The database was created by a research team working at the intersection of transport geography, development economics, and geospatial analysis. It addresses the long-standing problem that transport data for Africa is fragmented (scattered across national agencies, international organisations, and crowdsourced platforms), inconsistent (different classification systems, formats, and vintages), and incomplete (many countries lack comprehensive transport infrastructure inventories).
Key Features

2. Data Content
2.1 Road Network
The road network layer is the largest component of the database:
| Attribute | Description |
|---|---|
| Geometry | LineString geometries representing road segments |
| Classification | Harmonised road hierarchy (trunk, primary, secondary, tertiary, unclassified) |
| Surface type | Paved, unpaved, gravel, earth (where data available) |
| Lanes | Number of lanes (where data available) |
| Condition | Road condition category (where data available -- coverage is limited) |
| Bridge/tunnel | Identification of bridges and tunnels |
| Source | Data provenance (OSM, government, other) |
Sources: Primarily OpenStreetMap, supplemented and validated with:
- National road agency data (where available and accessible)
- World Bank road network databases
- Satellite-derived road detection (for validation)
- Previous academic datasets
Coverage notes:
- Primary and trunk roads: generally complete across the continent
- Secondary roads: good coverage in most countries
- Tertiary and local roads: coverage varies enormously; some countries have excellent OSM coverage (e.g., Kenya, Tanzania), while others have major gaps (e.g., DRC, Central African Republic)
2.2 Rail Network
| Attribute | Description |
|---|---|
| Geometry | LineString geometries representing rail lines |
| Status | Operational, non-operational, under construction, planned |
| Gauge | Track gauge (Cape gauge 1067mm, standard gauge 1435mm, metre gauge 1000mm, etc.) |
| Electrification | Electrified or non-electrified |
| Operator | Operating entity (where known) |
Coverage notes:
- Continental rail network is relatively well-mapped (Africa's rail network is smaller and more concentrated than its road network)
- Includes historical/abandoned lines, which are important for understanding potential rehabilitation options
- New standard gauge railways (e.g., SGR in Kenya, Addis Ababa-Djibouti) included
2.3 Ports
| Attribute | Description |
|---|---|
| Geometry | Point locations |
| Name | Port name |

| Size/class | Major, medium, small |
| Throughput | Annual cargo volume (where data available) |
| Container capacity | TEU capacity (where data available) |
| Country | Country code |
Coverage: Covers major commercial ports, fishing ports, and inland ports. Approximately 200+ ports across the continent.
2.4 Airports
| Attribute | Description |
|---|---|
| Geometry | Point locations |
| Name | Airport name |
| ICAO/IATA codes | International designations |
| Type | International, domestic, military, private |
| Runway | Length, surface type |

2.6 Derived Datasets
The database may also include derived analytical products:
- Travel time surfaces: Raster maps showing estimated travel time to nearest city/market
- Accessibility indices: Population-weighted measures of transport access
- Network connectivity metrics: Graph-theoretic measures of network connectivity by country and region
- Road density maps: Km of road per sq km or per capita, by administrative unit
3. Geographic Coverage
3.1 Country Coverage
All 54 African Union member states are included. Data quality varies by country:
High quality (good OSM coverage + government data): South Africa, Kenya, Tanzania, Ghana, Rwanda, Uganda, Morocco, Tunisia, Egypt, Senegal, Botswana, Namibia
Moderate quality (reasonable OSM coverage): Ethiopia, Nigeria, Mozambique, Zambia, Zimbabwe, Malawi, Cameroon, Ivory Coast, Mali, Burkina Faso
Lower quality (sparse OSM, limited government data): DRC, Central African Republic, South Sudan, Eritrea, Somalia, Chad, Equatorial Guinea, Guinea-Bissau
3.2 Temporal Coverage
The database represents a snapshot at the time of compilation (circa 2022-2023). It is not a time-series database. Historical changes (e.g., new road construction) are not tracked within the database itself, though the operational status of rail lines provides some temporal information.
4. Methodology
4.1 Data Collection
The research team used a multi-source approach:
- OpenStreetMap extraction: Bulk download of OSM transport features for Africa, filtered and classified
- Government data integration: Where national road agencies or transport ministries provided official network data, this was compared with and used to enhance the OSM base
- International organisation data: World Bank, AfDB, and other international organisation datasets were cross-referenced
- Satellite validation: Selected areas were validated against satellite imagery (e.g., Google Earth, Sentinel-2) to assess completeness
- Literature review: Previous academic datasets (e.g., GRIP global roads database, Natural Earth roads) were compared
4.2 Harmonisation
A key contribution of the database is the harmonisation of road classifications across countries:
- African countries use different road classification systems (national, regional, district, community roads; or A/B/C/D classifications; or numbered route systems)
- The database maps all country-specific classifications to a harmonised hierarchy (trunk, primary, secondary, tertiary, unclassified)
- The mapping methodology is documented, enabling users to trace how national classifications were converted
4.3 Quality Assessment
The data descriptor includes a quality assessment section covering:
- Completeness analysis (comparison with known network lengths from government statistics)
- Positional accuracy assessment (sample-based comparison with high-resolution imagery)
- Attribute accuracy (surface type, classification validation)
- Consistency checks (network topology, connectivity)

6. Strengths and Limitations
Strengths
- Continental scope with harmonised schema: No other open dataset covers all of Africa with a consistent transport infrastructure classification
- Multi-modal: Covers all major transport modes in a single dataset
- Peer-reviewed: Publication in Scientific Data ensures methodological transparency and quality documentation
- Open access: CC BY 4.0 license allows unrestricted use, including commercial applications
- Reproducible: Processing code is available, enabling updates and validation
- Citable: DOI and published paper provide proper academic attribution
- Fills a critical gap: Africa is the continent with the weakest transport data coverage; this database directly addresses that gap
Limitations
- Static snapshot: The database is not continuously updated; it represents a single point in time
- OSM dependency: Road network completeness mirrors OSM contributions, which are uneven across Africa
- Limited attribute data: While geometries are comprehensive, attributes (condition, traffic volume, surface quality) are sparse for much of the continent
- No operational data: The database covers infrastructure (physical assets) but not services (bus routes, freight flows, etc.)
- No time dimension: Cannot be used for trend analysis without comparison with other temporal snapshots
- Condition data gap: Road condition (IRI, roughness) is largely absent -- this is one of the most policy-relevant attributes but also the hardest to obtain
- Potential for rapid obsolescence: Africa's transport networks are changing rapidly (new roads, new railways); the dataset may become outdated

| African Transport Systems DB | Africa (54 countries) | Road, rail, port, airport, waterway | Classification, surface, status | Static (research publication) | CC BY 4.0 |
| OPSIS (open-gira) | Global | Road, rail, port, airport | Classification, hazard exposure | Periodic (research-driven) | ODbL/CC BY |
| GRIP (Global Roads Inventory Project) | Global | Roads only | Classification | Static (2018) | CC BY 4.0 |

The African Transport Systems Database's unique contribution is the harmonisation and quality control applied on top of OSM and other raw sources, specifically for Africa. Raw OSM data requires significant processing to be usable for analysis; this database provides that processed, analysis-ready product.
8. Integration Strategy for Global Transport Intelligence
What to Use
- Road network for Africa: Use as the primary Africa road layer, potentially in preference to raw OSM or OPSIS for African coverage
- Rail network for Africa: Harmonised rail data with operational status is difficult to obtain elsewhere
- Port and airport data: Complement with PortWatch and OurAirports data
- Accessibility metrics: If published, these derived products are directly useful for SDG monitoring and investment prioritisation
How to Integrate
- Download from repository: Obtain GeoPackage files from Zenodo/figshare
- Schema mapping: Map the African Transport DB schema to the global system's schema (harmonisation already partially done by the authors)
- Merge with OPSIS: For a global layer, use OPSIS for rest-of-world and the African Transport DB for Africa, resolving overlaps at boundaries
- Enrich with attributes: Layer on additional data from ATO (statistics), PortWatch (port activity), and World Bank (investment data) to add operational attributes to the geometric base
- Update mechanism: Periodically re-download and compare; alternatively, run the authors' processing scripts against updated OSM extracts to generate updated versions
Priority Use Cases
- Pan-African transport connectivity analysis: Which countries/regions are best/worst connected?
- Trade corridor assessment: Combined with PortWatch port data, assess the complete land-to-sea logistics chain
- Climate vulnerability: Overlay OPSIS hazard data on the African transport network
- Investment gap analysis: Compare existing infrastructure with traffic demand and economic activity
- SDG 9.1.1 monitoring: Use road network and accessibility data to estimate the Rural Access Index
