VISSIM Simulation-Based Traffic Optimization Solution: Case Study in Nanjing, China

On the basis of traffic survey, an improved simulation model is established by using the VISSIM to simulate the traffic running operation of the Beijing West Road in Nanjing, China. By considering the evaluation of the real traffic situation, two optimized solutions are proposed to relieve the traffic congestion which is caused by the traffic tidal phenomenon. A simulation model is built, with the help from the two optimized solutions. Data about travel time, queue length, vehicular delay, vehicular stop delay and number of stops are generated. Via analyzing and comparing these significant indicators, the results show that the proposed solution is better than the solution of Green-band Traffic. The VISSIM simulation-based optimization solution in this paper is effective.
