Abstract

The persistent traffic congestion in Dhaka, Bangladesh, calls for innovative and efficient solutions tailored to its unique urban dynamics. This study introduces a novel approach to traffic bottleneck identification that combines congestion levels and their potential to spread, addressing the critical need for targeted traffic management. Our methodology integrates traffic data collection through Google Maps snapshots, congestion intensity mapping, congestion spreading graphs (CSG), maximal spanning trees (MST), and applying Nä ıve Bayes’ theorem to calculate congestion costs. These tools identify bottlenecks by quantifying both congestion impact and propagation costs within the urban road network. Key findings highlight three major bottlenecks: Kawran Bazar, Mohammadpur Bus Stand, and Dhanmondi 32 intersections, validated using the SUMO simulation platform. These points exhibit significant congestion spread and network-wide delays. The proposed methodology not only identifies critical bottlenecks effectively but also offers actionable insights for urban planners and policymakers to devise targeted interventions. This research bridges existing gaps, providing a cost-effective, adaptable framework for mitigating traffic challenges in resource-constrained cities like Dhaka.
