| 摘 要： | 以四相位单交叉口为研究对象,计算推导交叉口的延误计算模型,包括公交优先相位减少的延误以及非公交优先相位增加的延误。模型以减少人总延误最大为控制目标,采用粒子群算法优化求解,从而得到最优的绿信比,并通过仿真算例验证算法的有效性。

| Abstract: | Establishes a delay model for a four-phase single intersection under saturation state.The delay model includes two parts,reduced delay in the bus priority phase and increased delay in other phases.Aimming at minimizing the people total delay of the intersection,it uses the PSO to optimize the delay model to get the optimal green ratio.And uses simulation example to show the effectiveness of the delay model. |
