Two years after the World Bank-funded CASE signals were written off, Dhaka is trying again with its own money: the Dhaka Transport Coordination Authority coordinates, BUET engineers, and the two city corporations (DNCC and DSCC) fund a 22-intersection semi-automatic signal programme stretching from the High Court to the Airport. The first seven junctions — Hotel InterContinental, Banglamotor, Sonargaon, Farmgate, Bijoy Sarani, the Chief Adviser's Office and Jahangir Gate — went live on 30 August 2025, each run from a police box where a controller, two traffic-police operators and BUET representatives adjust the automated cycles to live conditions. Police and press report better order at the equipped crossings, but drivers still routinely run reds, and the remaining 15 intersections were still uninstalled seven months after inauguration amid procurement complications and staff turnover.
📊 Impact
Press and traffic police report improved order and compliance at the seven equipped intersections, but no independent measurement has been published; 15 of the 22 planned intersections remained uninstalled seven months after launch.
🎓 Lesson
Dhaka's earlier signals died for lack of operators, not hardware. The new design builds the operators in — a staffed police box at every junction — but procurement, not technology, is again the bottleneck.
