| 摘 要： | 采用延误分析法研究路口拓宽后信号交叉口的服务通行能力，利用交通仿真软件VISSIM对拓宽交叉口进行交通流微观仿真，从而得到拓宽车道的延误曲线，建立了基于交通仿真的拓宽交叉口延误-流量模型．依据该模型提出了拓宽左转车道的基本服务通行能力的建议值，并给出了各修正系数以及实用服务通行能力的确定方法．

| Abstract: | Delay analysis method is adopted to study the service capacity of a widened intersection. Traffic simulation software VISSIM is used for microscopic simulation of a widened intersection so as to obtain a delay curve. The delay volume model of a widened intersection is established based on traffic simulation. The suggested value of basic service capacity of the widened left turn lane is given along with how to determine correction factors and practical service capacity. |

| Keywords: | traffic simulation widened intersection service capacity average delay |
