可变交通信息牌的最优分布模型
THE OPTIMAL LOCATION OF VARIABLE MESSAGE SIGNS
-
摘要: 本文就城市路网中可变交通信息牌（Variable Message Signs，VMS）分布地点的最优选择进行了研究，分析了VMS分布的一般规则，并建立了相应的数学模型．针对整数规划模型的求解复杂性，采用了遗传算法．算例表明了模型的有效性．Abstract: This paper deals with the optimal location problem of VMS in the urban traffic network. Based on the experiential rules, the mathematical models for the optimal location of VMS are proposed. The genetic algorithm is adopted to solve the proposed integer programming models. Finally, a numerical example is provided to illustrate the application of the models and the algorithms.
