摘要：支路体系缺失是中国城市道路网络的通病。在干— 支平面交叉口规划中，基于支路相邻的干–干平面交叉口信 号配时，提出了干–支平面交叉口可利用绿灯时长的计算方 法。利用VISSIM 软件对干–支平面交叉口进行交通仿真分 析，结果表明，合理设计、配时的干–支十字型交叉口对干路 通行能力、车速的影响极小，而未经合理设计时其不利影响 很大。最后指出，干–支平面交叉口的合理规划与信号控制 是健全支路系统的关键。

Abstract：Lack of local roadway (or collector roadway) system is a problem commonly existing in urban roadway network in China. For signal timing design for intersection of arterial and local roadways, a signal timing design method is proposed, which green time allocation is based on demand on both roadways. The results from the simulation analysis with VISSIM show that cross-shaped intersection of arterial and local roadways with proper design and signal timing has quite small impact on the capacity and travel speed of arterial roadway. However, the impact of the ill-design signal timing will be significant. Finally, the paper points out that proper planning and design for signalized intersection of arterial and local roadways is crucial in improving local roadway system.
