摘要
通过对线控系统上的四个交叉口交通量数据和信号配时数据进行调查,利用Vissim仿真软件对该线控系统进行仿真,对其中一个路段上的一个断面车辆到达情况进行分析,首先改变路段的长度,对比路段长度变化前后的车队离散数据,得到车队离散特性与路段长度之间的关系;其次改变路段上车流的分布函数,对比车流分布变化前后的车队离散数据,得到车流分布与车队离散特性之间的关系。通过对车队离散特性进行分析以及研究,为城市道路网交通流优化控制提供依据。
Based on the four intersection traffic signal timing data and data on the wire system to investigate,the use of the remote control system vissim simulation software to simulate a cross-section of one of the vehicles on the road to reach the situation analysis,the first length change sections,compared to a discrete section of the team before and after the data length,has been the discrete nature of the relationship between the team and the road between the length,followed by changes in the distribution function on road traffic and fleet discrete data traffic distribution before and after contrast,has been the team discrete nature of the relationship between the traffic distribution.Through the discrete nature of the team to analyze and research,can provide a basis for the urban road network control traffic flow optimization.
