Abstract

In response to Dhaka’s ever-increasing traffic demand, ride-sharing schemes offer a promising solution to enhance urban mobility thereby alleviating chronic congestion. While ride-hailing services are already prevalent in Bangladesh, they have fallen short of playing a major role in reducing traffic congestion. This study investigates the potential of shared mobility services in Dhaka and their implications for cost savings, socio-demographic preferences, and overall traffic efficiency. The research includes a questionnaire survey conducted among non-private vehicle users using simple random sampling to assess willingness to adopt shared services and identify key barriers, including safety concerns and technological limitations. Alongside, real-life traffic scenario is simulated using VISSIM to evaluate the impact of shared mobility on congestion. The data are analyzed using descriptive statistics and statistical modeling techniques. For the simulation purpose, two major intersections from the Dhaka Road network are modeled. Different shared vehicle scenarios (0%, 25%, 50%, and 100%) are tested to assess their effect on congestion. Results indicate that shared trips reduce per-passenger costs and increase vehicle occupancy. Significant reduction in congestion is observed, despite initial user hesitancy. However, shared vehicles may create bottlenecks when they stop on the curbside or operate on low-capacity links. The findings suggest that shared mobility can enhance transport accessibility in Dhaka, provided that operational challenges such as route optimization and safety are addressed. This study contributes to the growing literature on shared mobility in developing cities and offers policy recommendations for sustainable urban transportation planning.
