| 摘 要： | 考虑到交通波对交叉口车辆排队长度的影响,运用交通波理论对计算平面交叉口信号控制最短周期的Webster算法进行改进,并利用实测数据对改进后的算法进行验证,验证结果表明：该模型的预测精度可达到87%以上,满足信号配时和交通管理的需要。

| Abstract: | By considering the influence of traffic waves on vehicle queuing length in intersection, traditional Webster algorithm is amended, and a revised formula for minimum cycle calculation in intersection signal control is introduced by traffic wave theory. And using the practical survey data to verify the revised calculation ,practical survey data proved the prediction accuracy is above 87%, it is enough to meet the requirement of signal timing and traffic managemen. |
