The invention discloses a road traffic jam early warning system and method. The road traffic jam early warning system comprises a vehicle analysis module and a vehicle speed measurement module, wherein the vehicle analysis module comprises a vehicle counting module and a vehicle model identification module; the vehicle counting module and the vehicle model identification module control a laser generator to emit laser and a laser receiver to receive laser; and output ends of the vehicle counting module and the vehicle model identification module are connected with a signal transmission module,the signal transmission module is connected with a processor, the processor is connected with a data analysis module, the output end of the processor is connected with a wireless network transmissionmodule, and the wireless network transmission module is connected with a vehicle-mounted signal receiving module through a mobile network. Reliable congestion early warning information is obtained byanalyzing the vehicle speed, the vehicle model and the number of different vehicle models, and the technical defects that a road congestion early warning platform mostly uses a single sensing device as a data acquisition source, and the acquired data is incomplete are overcome.

    本发明公开了一种道路交通拥堵预警系统及方法,该系统包括车辆分析模块和车速测量模块,该车辆分析模块包括车辆计数模块和车辆型号识别模块;车辆计数模块和车辆型号识别模块控制激光发生器进行激光发射和激光接收器进行激光接收;车辆计数模块和车辆型号识别模块的输出端连接有信号传输模块,信号传输模块上连接有处理器,处理器上连接有数据分析模块,处理器的输出端上连接有无线网络传输模块,无线网络传输模块通过移动网络连接有车载信号接收模块。本发明通过对车速、车的型号以及不同车型的数量进行分析,得到了可靠的拥堵预警信息,克服了道路拥堵预警平台多以单一传感设备作为数据采集来源,采集的数据不完善的技术缺陷。
