Simulation and Optimization on the Fixed Time and Route Carpool Project Based on HOV Lane

To promote the fixed time and route carpool project in urban road, and then encourage more commuters to choose the carpool, HOV Lane can be set on the major commuter sections. Firstly, a typical road section of Huai’an was surveyed and analyzed to determine the initial HOV lanes setting schemes. Then, VISSIM was used to analyze the differences between existing road and simulation section. Finally, optimization on the initial schemes was made based on the simulation results. It proved that the HOV Lane, especially with reasonable limitation on passengers’ number, can obviously improve the traffic efficiency of urban network. The average speed increased by 5.94%, while the average queuing delay reduced by 57.75%.
