Abstract

Traffic congestion is one of the significant problems in Dhaka city. It is exacerbated by slow-moving non-motorized vehicles, illegal parking, makeshift shops on the road, and manually operated fixed-time traffic signals. These factors cause substantial delays, and residents lose valuable working hours daily. In this study, we evaluated the potential of Exclusive Bus Lanes (EBLs) and demand response Vehicle-Actuated Traffic Signal Controllers (VATSCs) to mitigate this issue. We conducted our study in one of the busiest corridors of Dhaka, from the Azimpur intersection to the Science Lab intersection. Using the micro-simulation software PTV Vissim, we examined four different traffic scenarios: (1) an ideal scenario, where no lane is blocked; (2) an existing base scenario, where one lane in some parts of the roads is blocked; (3) a worst-case scenario, where two lanes in some parts of the roads are blocked; and (4) a proposed scenario incorporating EBLs, VATSCs, high-capacity bus and the removal of non-motorized vehicles. Key performance indicators such as average delays, average speed, and person throughput were compared across the scenarios. The proposed scenario showed the most significant improvements, with 91.5% lower delays, 512% higher speeds, and 70% greater person throughput compared to the worst-case scenario. It showcases the potential of EBLs and VATSCs as sustainable traffic solutions for dense urban areas like Dhaka.
