| 摘要: |
| 为进一步提升信号交叉口控制方案的控制效率,提出一种考虑流线搭接的最优信号控制方案算法. 算法首先分析和细化流线相容关系,确定相位流线组合；然后将相位流线组合采用数组表示并随机抽样排列,根据信号控制方案相位流线的设置要求,充分考虑流线搭接,选取满足条件的相位组合方案作为交叉口可行相位组合方案；最后结合已有的配时模型,计算信号相位配时及车辆平均延误,通过对比车辆平均延误,选取最小延误对应的控制方案作为交叉口最优控制方案. 结果表明:算法所确定方案的车辆平均延误相比环栅结构相位组合方案减少0.3 s/pcu,分流式相位组合方案减少0.5 s/pcu,组合式相位组合方案减少4.5 s/pcu,由此说明此方法可行. |

| Abstract: |
| To improve the control efficiency of the signalized intersection control scheme, the algorithm for optimal intersection signalization scheme was proposed by considering movement lapping. Firstly, the movement compatibility relation in intersections were analyzed and refined, and the phase movements’ combination was determined. Then, the phase movements’ combination was represented and the random samplings were re-arranged. According to the phase setting requirements of intersection signal control scheme, the feasible phase combination (FPC) schemes for intersections were obtained by selecting the phase combination schemes satisfying the condition and consideration of the movement lapping. Finally, the signal phase timing and average vehicle delay were calculated by combining the existing timing model, and the control scheme corresponding to the minimum average delay was selected as the optimal control scheme of the intersection by comparing the average vehicle delay. Analysis results showed that the average delay of movement vehicles under the proposed scheme was reduced by 0.3 s/pcu compared with the ring barrier controller structure phase combination scheme (RBS), 0.5 s/pcu compared with the diffluence phase combination scheme (DS), and 4.5 s/pcu compared with the combination phase combination scheme (CS). Therefore, it showed that the proposed method is feasible. |
