珠海市人民西路交通组织优化设计 摘 要 在社会的发展过程中，城市机动车的数量日益增长，因此导致城市路网压力也日益增大，城市交通拥堵在整个路网结构中不断涌现。道路交叉口是城市路网交通的关键所在，是最容易发生交通冲突的地方。因此，对道路交叉口进行交通组织优化设计是十分重要的，能够以此提高道路交通的安全性和效率性。 本文结合珠海市人民西路交叉口实际交通情况，依据参考文献理论对道路交叉口进行渠化设计，最后利用软件VISSIM模拟交叉口在以韦伯斯特法进行信号配时得出的新的交通信号控制方式下的运行情况。最后根据交通延误、排队长度和行程时间等仿真数据来确定新的信控方式与原相位信号控制之间的优势，以此提高人民西路交叉口的通行能力。 关键词：韦伯斯特；交通流分配；交通仿真；优化路段； Traffic organization optimization design of Renmin West Road in Zhuhai Abstract In the process of social development, the number of urban motor vehicles is increasing day by day, which leads to the increasing pressure of urban road network, and urban traffic congestion is emerging in the whole road network structure. Road intersection is the key of urban road network traffic, and it is the place where traffic conflicts are most likely to occur. Therefore, it is very important to optimize the traffic organization design of Road intersection, which can improve the safety and efficiency of road traffic. In this paper, according to the actual traffic situation of Renmin West Road intersection in Zhuhai City, according to the theory of references, the design of the road intersection is channelized. Finally, the software VISSIM is used to simulate the operation of the intersection under the new traffic signal control mode, which is obtained by the Weber method of signal timing. Finally, according to the simulation data of traffic delay, queue length and travel time, the advantages between the new signal control mode and the original phase signal control are determined, so as to improve the traffic capacity of Renmin West Road intersection.
