基于三层路网优化策略模型的关联交叉口序列研究

Researches on Sequence Associated with Intersection Based on Three-tier Road Network's Optimal Control Model

以若干个连续交叉口构成的关联交叉口序列为单位,对平面信号交叉口相位的禁/放行状态进行优化建模;建立以减少延误时间和平均排队长度为目标,同时考虑驾驶员的主观心理-生理因素,寻求平面信号最优控制交叉口配时参数为最终目标的三层路网优化控制模型;最后构造出与驾驶加速度紧密关联的、三层模型架构下的目标策略函数。

Several intersections associated with each other compose a sequence as a unit, which optimally control the status of forbidding or releasing; Signal control so as to reduce delayed time and average queue length, at the same time consider to combine the driver＇s subjective mental-physical factors, and to find the optimal control plane signals when the timing parameters of intersection that belongs to three-layer road network＇s optimal control nmdel and establish the target control function based on the framework of model closely related to the driving acceleration.
