摘要
为解决高速公路收费站与平面交叉口通行能力不匹配导致车辆排队溢出的问题,该文通过分析收费站与平面交叉口之间的交通运行特征,结合车辆变道行为,给出最大排队长度计算公式.考虑因收费站与平面交叉口间距过近而导致两者之间交通运行存在强耦合关系,因此建立一个统一的联动控制优化模型.研究表明:若平面交叉口衔接方向排队长度超过允许的最大排队长度,部分车辆难以寻找到合适的变道机会而停车等待,破坏了收费站与平面交叉口稳定的运行状态;联动控制在3种流量方案(方案2、4、6)中相较于常规控制,车均延误分别降低了6.48%、13.43%、10.46%.
Abstract
In order to solve the problem of vehicle queuing overflow caused by the mismatch between the expressway toll stations and the capacity of plane intersections,the formula for calculating the maximum queue length was given by analyzing the traffic operation characteristics between toll stations and plane intersections and considering vehicles'lane-changing behavior.Due to the strong coupling of the traffic operation between toll stations and plane intersections caused by a short distance between them,a unified linkage control optimization model was established.The research shows that if the queue length in the connecting direction of the plane intersections exceeds the allowable maximum queue length,some vehicles find it difficult to find a suitable lane-changing opportunity and thus will stop and wait,which affects the stable operation state of the toll stations and plane intersections.Compared with the conventional control,the linkage control reduces the average vehicle delay by 6.48%,13.43%,and 10.46%in three traffic schemes(schemes 2,4,and 6)respectively.
