The invention relates to the technical field of traffic, in particular to a road section pedestrian crossing maximum pressure signal control method considering motorcade discretization. The method comprises the steps of performing regional division on a road section; predicting the traffic density of each region of the road section; establishing a maximum pressure signal control method based on segmentation density; and a signal timing optimization strategy. According to the invention, based on the traffic signal control model of the segmented density maximum pressure, the traffic characteristics of the pedestrian crossing intersection of the road section are fully considered, the density is selected as the weight parameter of the maximum pressure signal control, the traffic demand is accurately described, the actual traffic operation state can be better reflected, and the model precision is effectively improved. According to the method, the difference between the pedestrian traffic characteristics and the motor vehicle traffic characteristics is fully considered, the defect that the maximum pressure signal control model takes the queuing length as the pressure weight is overcome, and the reliability of the model calculation result is higher.
本发明涉及交通技术领域,尤其涉及一种考虑车队离散的路段行人过街最大压信号控制方法。步骤包括对路段进行区域划分;对路段各区域交通密度进行预测;建立基于分段密度的最大压信号控制方法;信号配时优化策略。本发明基于分段密度最大压的交通信号控制模型,充分考虑路段行人过街路口交通特性,选择密度作为最大压信号控制的权重参数,精确描述交通需求,更能反映实际的交通运行状态,有效提高了模型精度。本发明充分考虑了行人交通特性与机动车交通特性之间的差异,克服了最大压信号控制模型以排队长度作为压力权重的考虑不足,模型计算结果可靠性更强。
