Asian Transport Outlook Database


Asian Transport Outlook (ATO) is initiated by the Asian Development Bank (ADB) to strengthen the knowledge base on transport in the Asia-Pacific region. The ATO is developed in support of the planning and delivery of ADB Transport Sector Assistance. The ATO also supports Asian governments in transport policy development and delivery. ADB is working with other interested parties in developing the ATO as an instrument to track the implementation of the Sustainable Development Goals (SDG), the Paris Agreement and other relevant international agreements on sustainable development in the transport sector.

The ATO covers 51 economies in the Asia Pacific region, including all developing and developed ADB members in the region as well as the Islamic Republic of Iran and the Russian Federation. The initial design of the ATO was developed during Phase 1 (November 2020 – May 2021). During this phase an initial set of 463 indicators was identified, divided over eight workbooks. A substantive start was made with the population of a National Transport Database, from primary and secondary data. It also made a start with the documentation of the institutional frameworks, policies, and financing of transport in the ATO economies.

Following Phase 1, an Interim Phase (June 2021 – September 2021) was implemented during which an Urban Transport Database was developed covering 460 cities and which included 80 indicators. A baseline report was developed for the Aichi 2030 Declaration on Environmentally Sustainable Transport as well as a status report on the implementation of the Sustainable Development Goals in the Transport Sector in the ATO economies.

Phase 2 of the ATO (November 2021 – November 2022) expanded information in both the National Transport and the Urban Transport Database. The national indicators have been streamlined to exclude pending indicators and projection indicators and which will be added back once data is available. To further broaden the knowledge base on transport a cost database was developed. To gain insight in the development of the transport sector in Asia the Asia 2030 Transport Outlook was developed. The web-based interface at was also developed during this period.

Planning for Phase 3 of the ATO (2023-2024) is currently underway.

National Socio-Economic (SEC)

Socio-Economic, (SEC), describes all information on: (a) socio-economic parameters that drive the development of transport, and (b) specific economic impact of transport and its externalities on society at large.

Miscellaneous (MIS)

Miscellaneous (MIS) this is a rest category for all other indicators.

National Policy (POL)

Policy (POL) provides an overview of transport policy documents and policy targets, covering all categories of the ATO.

ATO Urban Database (XLSX)

The ATO Urban Database contains indicators on Infrastructure, Urban Form, Structure and Land-use, Activity and Services; Access and Connectivity, Road safety; Air Pollution and Health; Climate Change; Socio-Economic; and Miscellaneous 

A detailed assessment on selected 41 urban centers was conducted which provided additional detailed indicators, transport-related targets, and city-level policies:

ATO Cost Database

The ATO Cost Database is a unique ‘Transport Infrastructure Cost Database’ for Asian economies. The main objective of the database is to provide insights on transport infrastructure cost data to MDBs, Policy makers and Civil Society. A web-based interface is available at
