Abstract
Control effects of arterial green wave are affected by vehicles in and out of sub-arterial roads and pedestri-ans.A two-phase queuing and dissipation model is updated into a four-phase model based on the analysis results regarding the impact of left-turning vehicles from upstream sub-arterial roads on the downstream intersection.Traditional offset is then optimized based on this model,traffic delay caused by pedestrians is then computed on the basis of influences of pe-destrians on arterial traffic by using a weighted average method.This paper optimizes the traditional offset as well.Vissim software is used to verify the model.Compared with the traditional control of green wave,the results show that the im-proved control method can reduce average delay by 20.5% and average stopping time reduces by 17.6%,average parking frequency reduces by 8.7% and average travel time reduces by 3.5 s.Therefore this optimized method could improve the performance of green wave.关键词
