摘要:结合北京市可变信息板(VMS)应用现状,研究在不同道路状况下VMS对驾驶人路径选择行为的影响。通过SP调查收集相关数据,引入重力模型和Logit模型进行数据分析,利用VISSIM软件实现了静态交通模拟和动态交通模拟。研究表明,当部分驾驶人按照VMS提示信息选择替代路径后,道路拥堵状况得到缓解,路网平均延误时间减少23. 63%;随着路段车流密度增大,VMS诱导效用递增,在第46 min出现效用最大值;因拥堵造成平均车速在30 km·h-1左右的城市快速路最适宜设立VMS以改善路网运行状况。

Abstract:With respect to the application of variable message signs (VMSs) in Beijing, this paper conducts a research on the impact of VMSs on driver’s route selection behaviors in different traffic conditions. Based on Stated Preference survey data, the paper, taking advantage of Gravity and Logit models, performs a static and dynamic simulation in Vissim. The simulation results show that: 1) road congestion is relieved, especially when a portion of drivers change routes according to VMSs the average network delay is reduced by 23.63%; 2) the guiding effect of VMSs improves as the increase of vehicle density over a road segment, and reaches the maximum at the 46 minutes; 3) to improve traffic operation it is most suitable to use VMSs on urban expressway with a speed of 30 kilometers per hour as a result of congestion.
