The invention discloses an urban traffic situation awareness method and an early warning system based on big data. The system mainly comprises a detection unit, an alarm unit, a control unit, a cloudservice platform, an information transmission unit, a Beidou positioning service unit, a data storage unit, and a calculation unit. The detection unit is suitable for carrying out real-time, comprehensive and systematic detection and perception on the condition of each road line of a city through a plurality of detection modules. According to the urban traffic situation awareness method and earlywarning system based on big data, through the cooperation of the arranged cloud service platform and the detection unit, the detection unit collects data of parking spaces, smoke, vehicle flow, pedestrian flow, fleet length, vehicle speed, lane occupation, vehicle distance and driving time which influence urban road traffic through big data, and performs weighted averaging in combination with basic conditions of roads to obtain a traffic situation of a current urban whole road section. In this way, the overall situation of urban traffic can be accurately reflected.

    本发明公开了一种基于大数据的城市交通态势感知方法及预警系统,预警系统主要包括探测单元、报警单元、控制单元、云服务平台、信息传输单元、北斗定位服务单元、数据储存单元和计算单元,探测单元适于通过多个探测模块对城市的各个道路线路的情况进行实时、全面和系统化探测和感知。一种基于大数据的城市交通态势感知方法及预警系统,通过设置的云服务平台和探测单元配合使用,探测单元通过大数据对影响城市道路交通的车位、烟雾、车流量、行人流量、车队长度、车速、车道占用、车距和行车时间多种因素的数据进行采集,并结合道路的基本情况进行加权平均得出当前城市整体路段的交通态势,这样可较为准确的反映出城市交通的整体态势。
