| 摘 要： | 针对不同进口道形式对交叉口分类,利用杭州市信号交叉口的实际观测延误数据,以统计出的进口道饱和度和延误值为基础,通过对饱和度和延误值关系的分析拟合,得出适合杭州市信号交叉口的延误函数,应用于杭州市宏观交通模型中,可提高模型的精确程度,并且在杭州市交通信息平台中得到了验证。

| Abstract: | The intersections were classified according to the forms of approach,and the delay data of signalized intersections in Hangzhou City was observed.The delay function was defined by analyzing saturation-delay rela-tionship,which was based on statistical results.At last,it was used in Hangzhou macroscopic simulation model,and proved by Hangzhou traffic information system. |
