The invention relates to the technical field of intelligent traffic, in particular to a dynamic identification method for a risk level of a special road section in an intelligent network connection environment. Multi-source and multi-scale traffic data of a special road section are obtained, then abnormal operation state characteristics are extracted according to the multi-source and multi-scale traffic data, macroscopic risk analysis of lane congestion and microscopic risk analysis of collision between vehicles are carried out on the special road section according to the abnormal operation state characteristics, and then the risk level of the special road section is obtained. Therefore, the dynamic identification of the risk level of the special road section is realized, a vehicle driver is helped to obtain the risk level of the special road section in advance, the vigilance of the special road section is improved, more careful and reasonable driving operation is adopted to pass through the special road section, the traffic accident occurrence probability of the special road section is effectively reduced, and the driving safety is improved. And the driving risk of a special road section is reduced.
本发明涉及智能交通技术领域,具体涉及一种智能网联环境下的特殊路段风险等级的动态识别方法。通过获取特殊路段的多源多尺度交通数据,然后根据多源多尺度交通数据提取出异常运行状态特征,根据异常运行状态特征对特殊路段进行车道拥堵的宏观风险分析,以及车辆间碰撞的微观风险分析,进而获取特殊路段的风险等级,从而实现对特殊路段的风险等级的动态识别,以帮助车辆驾驶员提前获取特殊路段的风险等级,从而提高对特殊路段的警惕心,采用更加谨慎合理的驾驶操作来通过特殊路段,有效地降低了特殊路段的交通事故发生概率,降低了特殊路段的行车风险。
