Threshold values of traffic flow for the provision of exclusive bus lanes

A simulation network model was established using VISSIM software and verified by the T-test. The model took into consideration the road conditions, pedestrian crossing, traffic composition, bus stops and traffic signal. The operating characteristics of buses and cars under different flow conditions were studied using the simulation model, and the speed-flow models of buses and cars were established based on the simulation results. Finally, the threshold values of traffic flow for the provision of exclusive bus lanes was determined with the target of optimal travel benefits (per capita), which would provide a basis for the planning and design of exclusive bus lanes on urban roads.
