城市道路交通元胞传输模型构建方法及评估优化

Construction method and evaluation optimization of cellular transport model for urban road traffic

随着我国经济的发展和城市化进程的加快,缓解和预防交通拥堵成为众多城市发展的先行规划。在城市交通工程中,合理地改进交叉口设计对提高城市路网的运输效率有重要意义。该文主要从两方面对交叉口进行了研究。首先从动态网络交通流出发,研究交叉口的渠化设计方法;其次将渠化设计方法应用于实证,分析其应用效果。

With the development of China′s economy and the acceleration of urbanization process,mitigating and preventing traffic congestion has become the first planning for many cities′development.In urban traffic engineering,reasonable improvement of intersection design is of great significance to improve the transportation efficiency of road network.This paper mainly studies intersection from two aspects.Firstly,based on the dynamic network traffic flow,the channelization design method of intersection is studied.Secondly,the channelization design method is applied to empirical study and its application effect is analyzed.
