The invention provides a traffic detection system, which comprises: a plurality of piezoelectric sensors which are buried in a lane and used for generating piezoelectric pulse signals when being rolled by wheels; a traffic light connecting unit, which is electrically connected to a control unit and an external traffic light and is used for acquiring the working state of the external traffic light; and the control unit, which is used for receiving the piezoelectric pulse signals generated by the plurality of piezoelectric sensors, judging whether a road section is congested or not according to the piezoelectric pulse signals and the working state of the external traffic light, and sending a judgment result to a user, so that the judgment accuracy of the traffic flow is improved, and whether the current road section is congested or not is quickly determined.

    一种交通检测系统,包括:复数个压电传感器,埋设在车道上,用于当受到车轮碾压时产生压电脉冲信号;交通灯连接单元,电连接于所述控制单元及外部交通灯,用于获取外部交通灯的工作状态;控制单元,用于接收所述复数个压电传感器产生的压电脉冲信号,并根据所述压电脉冲信号及所述外部交通灯的工作状态判断路段是否拥堵,还用于将判断结果发送给用户,从而提高了对车流量的判断准确度,快速确定当前路段是否拥堵。
