Simulation Analysis on Optimal Merging Control of Connected Vehicles for Minimizing Travel Time

摘要

This study examined a cooperative merging control methodology for connected vehicles to optimize traffic flow without considering atraffic priorityon-priority at intersections. A cellular automata microsimulation was constructed to examine the methodology. It wasused for simulating the traffic condition and for predicting a future conflict between two vehicles at a T-junction or cross-junction.Optimum vehicle control patterns of the two vehicles for avoiding the conflict andminimizing the total travel time of all vehicles on theroad network was examined. Simulation results demonstrate that the proposed methodology can reduce total travel time and that thecontrol patterns become more diverse as the traffic volume increases.
