摘 要: 分析路段人行横道按钮式信号控制下行人延误、机动车延误和停车率及交叉口车辆延误和停车率。从协调信号控制的角度出发,以提高出行者时间效益和改善交通环境为目的,建立路段人行横道按钮式信号与交叉口信号协调控制优化模型。以协调系统延误和停车率最小为目标函数,以上游交叉口至人行横道的相位差、人行横道行人触动按钮后的等待时间、人行横道机动车相位绿灯时长、上游交叉口周期时长、各相位绿灯时长等作为决策变量,运用遗传算法(genetic algorithm,GA)对控制参数进行共同优化,并结合实例运用Synchro软件验证模型的有效性。
关 键 词: 公路运输;行人按钮式信号灯;干线协调控制;多目标规划

Abstract: The pedestrian delay, motor vehicle delay, vehicle stops at mid-block buttoned signal pedestrian crossing and motor vehicle delay, vehicle stops intersection were analysized. From the point of coordinating signals control and improving traveler time effectiveness and environments, this paper established coordinated control optimization model between mid-block pedestrians crossing buttoned signal and intersection signal. The minimum delay and vehicle stops were taken as objective functions, offsets, pedestrian waiting time, green time and cycles were taken as decision variables, the control parameters were optimized using genetic algorithm (GA). Then, this model was proved to be effective using case analysis combined with Synchro software.
Key words: traffic road; buttoned signal; signal coordinated control; multi-objective programming
