摘要
基于行程时间和路段长度信息给出了路段拥挤系数的概念,建立了子区交通状态矩阵,利用加权系数的方法计算整个协同子区的拥挤系数,进而对子区的交通状态进行判断。最后,利用VISSIM仿真软件建立路网对上述方法进行验证。试验表明,这种方法简单实用,可直接用于交通状态分析中,为协同策略的制定提供了背景环境方面的参考。
The concept of road segment congestion quotiety was introduced based on the information of travel time and segment length, and the traffic state matrix of the region was built. The congestion quotiety of the whole coordination region was calculated by averaging the weighted quotieties of the segments and was used to judge the traffic state of the region. A simulation road network was built based on the simulation software VISSIM to check the feasibility of the proposed method. Simulation results show that the method based on the congestion quotiety is simple and practical, can judge the traffic state,provides a background environment for the development of the coordination strategy.
