The invention discloses an intersection pedestrian crossing risk early warning method and system in an intelligent network connection environment, and the method comprises the steps: collecting the data of pedestrians and vehicles entering an intersection detection range in real time, extracting variable data representing the intersection traffic condition, environment characteristics and pedestrian motion characteristics based on different traffic individual trajectory data, and carrying out the early warning of the intersection pedestrian crossing risk. A pedestrian-vehicle conflict risk is calibrated based on a substitutive safety index PET, a pedestrian crossing risk prediction model of an intersection is constructed to carry out real-time risk discrimination and carry out risk early warning on pedestrians, and the crossing risk is reduced. According to the invention, on the basis of the intelligent network connection technology, the crossing risk of pedestrians at the intersection is discriminated in real time and early warned, so that the crossing risk is reduced.
本发明公开了一种智能网联环境下的交叉口行人过街风险预警方法及系统,实时采集进入交叉口检测范围内行人及车辆数据,基于不同交通个体轨迹数据,提取出表征交叉口交通状况、环境特征及行人自身运动特性的变量数据,基于替代性安全指标PET对人车冲突风险进行标定,构建交叉口的行人过街风险预测模型进行实时风险判别并对行人进行风险预警,降低过街风险。本发明依托智能网联技术,对交叉口行人过街风险进行实时判别并预警,降低了过街风险。
