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.
Signal control of intersection is an important means of urban traffic management, and urban signal congestion control needs to consider the signal optimization control strategy of the intersection.In view of this, for the four-phase fixed cycle single-intersection, using the store-and-forward method modeling, Performance index, a strategy based on multi-parameter programming is proposed.According to the arrival rate of intersection, the strategy adjusts the green time of each phase in real time in order to make full use of green time in the whole signal cycle. The simulation experiments on the PARAMICS platform show the effectiveness of the proposed control strategy.
