交叉口作为城市交通网络的关键节点,很大程度上决定整个城市路网的运行效率。行人、非机动车以及机动车组成的混合交通流在交叉口几何条件的影响下相互交织、相互作用,在交叉口极易产生拥堵、阻塞、噪音污染等现象。本文分析交叉口实际调查数据,引入VISSIM仿真,对现有信号控制方案优化改进,从多项改善方案选出最优。
As the key node of urban traffic network, the intersection largely determines the operation efficiency of the entire urban road network. The mixed traffic flow composed of pedestrians, non-motor vehicles and vehicles interweaves and interacts with each other under the influence of the geometric conditions of intersections. Congestion, congestion and noise pollution are easily caused at intersections. This paper analyzes the actual survey data at the intersection, introduces the VISSIM simulation, optimizes and improves the existing signal control scheme, and selects the best from several improvement schemes.
