一类含特殊路段的城市干道协调控制方法研究

在分析特殊路段交通特性及需求的基础上,对一类含特殊路段的城市干道协调控制方法进行了研究,提出基于主动性思维设计控制策略。通过干道协调控制人为调节关联交叉口交通阻抗来影响用户的交通行为选择,从而在某种程度上限制特殊路段交通的过度增长,在保障路段交通安全的基础上充分发挥交通效益。针对南方某城市隧道的实地情况和流量数据,设计出根据流量和排队长度两个参数综合选择实时控制方案的方法,进而说明该控制方法的具体实现及仿真效果。试验证明该方法对一类含特殊路段的城市干道协调控制具有指导意义。

Study on the Coordinate Control for Special Section Contained Road

Based on analyzing traffic trait and demand of the special section,coordinate control for special section contained road is studied and a new way to design the control strategy based on active thought is put forward.The control of excessive traffic volume increment on special section is achieved by adjusting the trunk traffic impedance of associated intersections to effect the travelers' behaviors,thus not only to assure the traffic safety but also to raise transportation efficiency.According to the situation and data of a tunnel in a city of south China,the method of choosing real time control plan synthetically is designed,which based on traffic volume and queue length.The way to realize the strategy and the simulaion effect are presented.The experiment result shows guiding significance for control of special section contained road.
