Reversible lane control system with low emission load based on VISSIM simulator

A reversible lane control system with low emission load is designed based on VISSIM simulation software. This system aims at the problem that the traffic flow of different directions at the intersection has the imbalance of time and space. Through the VISSIM simulation based on Python language, the second lane from the central separation belt is taken as the variable lane, and the lane control under different traffic flow conditions is realized. The system takes the queuing length, traffic delay time and carbon emissions of the intersections as the traffic efficiency evaluation indexes of the variable lane, and analyse the actual benefits of setting variable lanes to relieve the time and space resources of the intersections. Simulation results by using VISSIM and the designed Python interface show that, compared with the settings without variable lane control system, the average queue length at the intersection decreases by 38.6%, the maximum queue length by 36.4%, the average delay time by 20.7%, the maximum delay time by 15.1%, and the average carbon emission by 17.3%. It can be seen that the variable lane control system at intersections based on VISSIM has a significant effect on easing traffic congestion at intersections and reducing total carbon emissions.
