The invention provides a traffic intersection vehicle congestion detection method, which comprises the following steps: acquiring a road network diagram of a to-be-detected intersection, determining characteristics of flow data of vehicles passing through the to-be-detected intersection based on the road network diagram, and accessing traffic lights and environmental data of the to-be-detected intersection; determining a plurality of road sections of the to-be-detected intersection directly associated with the road network map based on the road network map, and collecting traffic parameters of the vehicle running on the plurality of road sections; according to the acquired vehicle flow data, the condition of the traffic signal lamp and the traffic parameters of the plurality of road sections, the traffic congestion degree is preliminarily judged, and congestion levels are divided according to the severity degree of the traffic congestion degree; and performing image judgment and analysis by using a video monitoring device according to the preliminarily judged traffic congestion degree. According to the traffic intersection vehicle congestion detection method, the traffic condition can be efficiently monitored and responded, support is provided for urban traffic management, and through real-time analysis and processing of the video data, the traffic congestion can be rapidly and accurately detected, and related departments and the public can be timely notified.

    本发明提供了一种交通路口车辆拥堵检测方法,获取待测路口的路网图,基于路网图确定经过待测路口的车辆流量数据的特征,并接入待测路口的交通信号灯和环境数据;基于路网图确定与之直接关联的待测路口的多个路段,并收集车辆行驶在多个路段的交通参数;根据获取的车辆流量数据、交通信号灯的情况以及多个路段的交通参数,初判交通拥堵程度并根据其严重程度划分拥堵级别;根据初判的交通拥堵程度,利用视频监控装置进行图像判断分析。本发明的交通路口车辆拥堵检测方法能够高效地监测和响应交通状况,为城市交通管理提供支持,通过对视频数据的实时分析和处理,本发明能够快速准确地检测出交通拥堵,并及时通知相关部门和公众。
