基于多属性决策的现代有轨电车动态信号优先控制策略
|
摘要
根据现代有轨电车的行车组织特点,分析了通过交叉口时不同车道布设形式对交从通流产生的影响。采用多属性决策(MADM)的思想,提出了在保证现代有轨电车现状出行效率的前提下,减少对其他车辆在交叉口造成延误的动态优先控制策略(DPS)。利用MATLAB软件对VISSIM交通建模软件中的VAP模块进行二次开发,以南京江东中路与河西大街交叉口为例,对现代有轨电车通过不同车道布设形式的交叉口分别采用现状绿波控制和DPS进行仿真。通过对比发现,在不同车道布设方式下,DPS均能有效降低现代有轨电车对交叉口社会车辆造成的延误。
The traffic flow at intersection according to the driving characteristics of modern tram with different lane layout types was analyzed with the dynamic priority strategy( DPS) based on the idea of multiple attribute decision making( MADM) for intersection delay.The VAP module in VISSIM software with MATLAB was used to simulate the induction control of the modern tram through the concrete intersection by the delay of the intersection with different lane layout types of modern trams. Taking the intersection of Middle Jiangdong road and Hexi avenue in Nanjing as examples,the traffic delay caused by different lane layout of modern trams was analyzed by using green wave control and DPS,respectively. It was found that the DPS effectively reduced the delay caused by the modern tram to the social vehicles in different lane layout types.
