摘要
机动车迅猛增长的同时导致交通拥堵日趋严重,尤其是早晚高峰城市快速路出入口的拥堵已成为交通管理部门的痛点与难点,简单的信号控制策略已经无法满足当前城市发展的需求,以北京市快速路为研究对象,通过对自适应和协调控制系统的检测器布设方案研究以及协同控制策略研究,根据不同匝道出入口类型在整个环路中所占的比例,以信号控制策略的实施效果与匝道出入口问距离、匝道出口和下游交叉口间距离的关系为重点,最终通过仿真得出采用综合信号控制策略后有利于提升整个快速路道路通行能力的结论。
The rapid growth of motor vehicles has led to increasing trattic congestion,especially during peak hours m the morning and in the evening,congestions at urban expressway entrances have become pain points and difficulties of the traffic management department,simple signal control strategies can no longer meet the needs of the current urban development. Taking Beijing Expressway as the research object,the paper,through the study of the detector layout scheme of the adaptive and coordinated control system and the cooperative control strategy and based on the proportion of different types of entrances and exits of ramps in the entire ring road,focuses the study on the relationship between the effect of signal control strategy and the distance between ramp entrances as well as the distance between ramp exits and downstream intersection,and finally come to a conclusion through the simulation that the traffic capacity of the whole expressway can be improved if a comprehensive signal control strategy is adopted.
