摘要
为实现干线协调下的单点自适应控制,首先将周期内的相位分解为固定部分和可变部分,并设定各相位的可变部分时长之和为定值;随后将协调方向及其相邻相位所在方向的进口道流量模糊化,并用规则集描述流量与相位可变部分的时长之间的关系;最终形成一套干线协调下的单点自适应控制方法。仿真结果表明,新控制方法对时变的交通流适应性更佳。
In this paper, in order to realize the adaptive control of a single signal during trunk line coordination, we first decomposed the phases during a cycle into the fixed part and variable part and set the sum of the duration of the variable part of all phases to be constant; then we turned fuzzy the coordination direction and the inlet flow of the neighboring phases and used rule set to describe the relationship between the traffic flow and the duration of the variable part, which ultimately led to the formation of a single-point adaptive signal comrol method during the process of trunk line coordination and regulation.
