交叉口信号控制是城市交通管理的重要手段,解决城市拥堵问题需考虑交叉口的信号优化控制策略.鉴于此,针对四相位定周期单交叉口,采用存储转发方法建模,以排队长度均衡为性能指标,基于多参数规划方法离线地给出交叉口信号的优化配时策略.该策略根据交叉口车辆到达率,实时地调整各相位绿灯时间,以实现整个信号周期内绿灯时间的充分利用.通过PARAMICS平台进行的仿真实验表明了所提出控制策略的有效性.

@@@@Intersection signal control is one of the essential approaches to urban transport management. The optimal signal timing strategy of intersection should be considered in order to solve the traffic congestion. A signalized intersection with four phases is investigated by the store-and-forward modeling, and a performance index based on queuing length balancing is proposed. The signal timing strategy is solved off-line via multi-parametric programming. According to the vehicle arrival rate, the green time of each phase is adjusted on-line based on the strategy to efficiently utilize passing time in whole cycle. The simulation on PARAMICS platform shows the effectiveness of the proposed strategy.
