摘要

To improve the traffic capacity in signalized intersections, stretching-segment are applied both in upstream and in downstream in some criteria and guidance. However, the methods to calculating the traffic capacity of signalized intersections usually consider the impact of stretching-segment in upstream. Based on investigations on some intersections in Chengdu, this study analyzes the impacts on traffic capacity caused by downstream stretching-segment, and shows that the length of downstream stretching-segment and the signal of the intersections are the two key factors for its capacity. Then this study investigate the trends and the extent of the impact using a VISSIM simulation model.
