EO-Informed Urban Transport Modelling in Dhaka, Bangladesh
The GDA AID Urban Sustainability team, working with the Asian Development Bank, is using Earth Observation (EO) technology to tackle Dhaka’s traffic crisis. EO data helps model traffic demand, infrastructure stress, and flood impacts, improving transport planning and decision-making.
Description
The GDA AID Urban Sustainability consortium, in collaboration with the Asian Development Bank (ADB) on the project “Updating of the Revised Strategic Transport Plan for Dhaka.” This project is helping to address Dhaka, Bangladesh’s severe traffic issues where authorities struggle with a transportation crisis affecting 24 million people, with the economic toll on Bangladesh accounting for 6 to 10% of national GDP. The project has used EO-derived data like land use and land cover maps which help determine where trips are generated and their destinations. The impact of floods on traffic and road closures were also studied using detailed computer models. Policymakers in Dhaka and other cities can use this data to compare the impact of various interventions on trip distribution, mode choice, and route assignment.
