The invention discloses an intersection driving risk assessment method and system and a storage medium, and relates to the field of intelligent traffic, and the method comprises the following steps: determining a vehicle conflict relation based on an expected driving track of a vehicle in an intersection; projecting the vehicles to a virtual lane to form a virtual motorcade; based on the vehicle conflict relationship, calculating the minimum safe distance between the own vehicle and the conflicting vehicle on the virtual lane; calculating the comprehensive driving risk of the vehicle based on the minimum safe distance and the actual distance between the vehicle and other vehicles; and designing a relative risk index based on the comprehensive driving risk, and outputting a driving risk level evaluation result. The driving risk in the intersection is measured by using the minimum safe distance on the virtual lane, and the potential risk can be sensed before the vehicle enters the intersection meeting area; the comprehensive driving risk is evaluated by using the minimum safe distance and the actual driving distance on the virtual lane, the driving risk level sensing sensitivity in the intersection is high, and the traffic safety of the intersection is improved.
本发明公开了交叉口行车风险评估方法、系统及存储介质,涉及智能交通领域,包括以下步骤:基于车辆在交叉口内的预期行驶轨迹,确定车辆冲突关系;将车辆投影到虚拟车道中排成虚拟车队;基于车辆冲突关系,计算自车与冲突车辆在虚拟车道上的最小安全距离;基于自车与其他车辆间的最小安全距离和实际距离,计算自车的综合行车风险;基于综合行车风险设计相对风险指数,输出行车风险水平评价结果。利用虚拟车道上的最小安全距离衡量交叉口内的行车风险,能够在车辆进入交叉口会车区域前感知潜在风险;利用虚拟车道上的最小安全距离和实际行车距离评价综合行车风险,对交叉口内的行车风险水平感知灵敏度高,提升交叉口车辆通行安全性。
