摘要交通是连接城市的重要纽带,而交通问题则是制约城市发展的重要原因之一。而本文则是对其中城市单交叉口进行仿真模拟实验,再现道路交叉口的车辆通行,以及对交通灯信号进行智能控制。
本文以城市交叉口控制为研究对象,选取南京升州路仙鹤街交叉口作为仿真对象。描述了一个四相位,11个入口车道的交叉口仿真模型。通过对算法的分析理解,结合系统设计来对单交叉口的进行仿真控制实验。49134
仿真系统采用C++编程语言进行设计,由车辆通行模块,交通灯控制模块组成,通过从数据系统中获取的车辆数据,进行十字交叉口的交通控制,模拟再现某个时段升州路仙鹤街的车辆同行。由于韦伯斯特配时法易受到交通量大小的影响并且车辆延误损失时间的同样会导致不同的仿真结果,所以本文将仿真测试选取合适的方法对韦伯斯特配时法进行优化。

Title Semi physical simulation of urban traffic signal network and large data information acquisition
Abstract
Traffic is an important link between cities.However,the traffic problem is one of the important elements which restricts the development of the cities. In this paper,the simulation experiments about the urban single intersection is carried out which represents a scene of the road intersection of vehicle traffic,and the intelligent control about traffic light signal is done.
This paper takes the city intersection control as the research object selecting Nanjing Sheng Zhou Lu Crane Street intersection as a simulation object which displays a simulation model of the intersection of four entrances and 11 phases. The simulation control experiments of the single intersection is carried out through the analysis and understanding of the algorithm, combined with the system design.
Simulation system is designed with C++ programming language consists of the vehicle access module and the traffic light control module.Realize intersection traffic control through the data of vehicles obtained from the system ,and simulate vehicles counterparts in Crane Road street in a certain period of time.The result of the simulation experiments using the Webster timing method is influenced by the traffic volume and vehicle delay loss of time easily.The paper optimizes the Webster timing method through appropriate methods.
