Abstract and Keywords

Abstract: In order to solve the phenomenon that the queuing of vehicles on the exit ramps and adjacent intersections of the expressway causes traffic congestion back to the toll plaza or even the main line of the expressway, under the current situation of the rapid growth of electronic toll collection (ETC) traffic at toll stations and the premise that the traffic organization cannot be improved, and based on the classic actuated control theory, this paper introduces the control of the speed of the ETC vehicles passing through the toll station, and adopts the method of semi-actuated control of the urban expressway toll station and the adjacent signal intersection. This method is used to simulate the Shihu toll station of the Guangzhou North Second Ring Expressway with VISSIM, utilizing the delay at the intersection and other parameters to evaluate the service level. The case simulation results show that this method can effectively improve the traffic efficiency of toll stations and adjacent intersections, reduce the average queue length of the traffic area by 42.3%, reduce the average delay time and the number of stops by about 20%, and improve the service level from D level to C level.

Keywords: expressway; semi-actuated control; delay; VISSIM software; electronic toll collection (ETC) vehicle

摘要和关键词

摘要: 为了解决高速公路出口匝道及衔接交叉口车辆排队导致交通拥堵倒灌至收费广场甚至高速公路主线的现象,文章结合目前电子不停车收费系统(electronic toll collection, ETC)车流量迅速增长的现状,提出在无法改善交通组织的前提下,基于经典的感应控制方法理论,引入对收费站通行的ETC车辆车速的控制,采用对城区高速公路收费站与衔接信号交叉口进行半感应控制的方法。以该方法借助微观交通仿真软件VISSIM对广州市北二环高速公路石湖收费站进行仿真实验,采用信号控制延误等参数评价服务水平。案例仿真结果表明,该方法可以有效地提高收费站及衔接交叉口的通行效率,使通行区域的平均排队长度减少42.3%,平均延误时间与停车次数下降约20%,服务水平由D级提高到C级。
