The invention provides a traffic saturation judgment system and device, and relates to the technical field of traffic control. The device comprises a first vehicle detector, a second vehicle detector, a first vehicle passing detector, a second vehicle passing detector and a processor, wherein the first vehicle detector, the second vehicle detector, the first vehicle passing detector and the second vehicle passing detector are wirelessly connected with the processor. A prediction calculation module obtains and receives vehicle number data sent by a first vehicle passing detector, a first vehicle detector, a second vehicle passing detector and a second vehicle detector, and the prediction calculation module firstly calculates the vehicle passing number when a to-be-detected lane is green and the waiting number when the to-be-detected lane is red. Meanwhile, the number of vehicles passing through the downstream lane during green light and the number of vehicles waiting for the downstream lane during red light are calculated, so that the saturation of the to-be-detected vehicles should be the number of the vehicles staying on the to-be-detected vehicles and the vehicles entering the downstream vehicles, and the accuracy of traffic saturation judgment is improved.

    本发明提供一种交通饱和度判定系统及装置,涉及交通控制技术领域。该装置包括一号车辆探测器、二号车辆探测器、一号车辆通过检测器、二号车辆通过检测器与处理器,所述一号车辆探测器、二号车辆探测器、一号车辆通过检测器和二号车辆通过检测器均与处理器通过无线连接。本发明,预测计算模块中获取接收一号车辆通过检测器、一号车辆探测器、二号车辆通过检测器以及二号车辆探测器发送的车辆数量数据,预测计算模块先计算待测车道绿灯时车辆通过数量以及红灯时等待数量,同时计算下游车道绿灯时车辆通过数量以及红灯时等待数量,因此,待测车辆的饱和度应当是待测车辆停留的车辆数量以及下游车辆进入的车辆,从而提高了交通饱和度判定的准确度。
