The invention discloses a pedestrian-vehicle conflict analysis method for a signal-control-free pedestrian crossing under mixed traffic flow. The method comprises the following steps: obtaining a pedestrian-vehicle conflict simulation model parameter corresponding to a to-be-analyzed signal-control-free pedestrian crossing; respectively constructing a pedestrian crossing behavior model, a traditional vehicle behavior model and an automatic driving vehicle behavior model, and constructing a pedestrian-vehicle conflict simulation model based on the pedestrian crossing behavior model, the traditional vehicle behavior model and the automatic driving vehicle behavior model; and adopting a pedestrian-vehicle conflict simulation model to extract the pedestrian-vehicle conflict behavior of the untrusted pedestrian crossing, and evaluating the severity of the extracted pedestrian-vehicle conflict behavior. The method is of great significance to guarantee the traffic safety of pedestrians at the unsignaled crossing after the automatic driving vehicle is deployed.
本发明公开了一种混合交通流下无信控行人过街横道的人车冲突分析方法,包括:获取待分析的无信控行人过街横道对应的人车冲突仿真模型参数;分别构建行人过街行为模型、传统车辆行为模型和自动驾驶车辆行为模型,基于行人过街行为模型、传统车辆行为模型和自动驾驶车辆行为模型构建得到人车冲突仿真模型;采用人车冲突仿真模型对无信控行人过街横道的人车冲突行为进行提取,并对提取的人车冲突行为的严重性进行评价。本发明对保障自动驾驶车辆部署后无信控过街横道处的行人交通安全具有重要意义。
