基于改进F-B模型的过饱和状态下交叉口信号配时优化方法
Optimization method of the improved F-B model based signal timing at oversaturated intersections
摘要
Abstract
To reduce the vehicle delay time at oversaturated intersections,the improved F-B signal timing model was established.The procedures of cycle calculation in this model were the same as those in F-B method.The concept of "real traffic volume" was put forward when investigating the flow rate of each approach,and the delay model was used to evaluate the F-B method and the improved F-B method.The case study indicated that,compared with the F-B signal timing model,the use of improved F-B model made the delay time of two neighboring intersections of Wenhua Road/Fushan Road and Wenhua Road/Hagongda Road decrease 34.39% and 28.05% respectively.The improved model can ease traffic jam effectively,and reduce vehicle queue length,and improve the intersection service level.关键词
