The embodiment of the invention discloses a safe vehicle distance prompting system and method for an expressway, and the system comprises a speed sensor array which is used for collecting the driving speed V < front > of a front vehicle and the driving speed V < rear > of a rear vehicle on a traffic lane; the signal controller is used for determining the safety distance L between the rear vehicle and the front vehicle according to the driving speed V < front > of the front vehicle and the driving speed V < rear > of the rear vehicle; and the signal controller is also used for controlling the ground signal lamp between the rear vehicle and the front vehicle in the ground signal lamp array to emit a corresponding indication light signal according to the safety distance L and the actual distance S between the rear vehicle and the front vehicle. By implementing the embodiment of the invention, the different indication light signals can be sent out through the ground signal lamp to indicate the rear vehicle, so that the rear vehicle can timely discover abnormity and make speed adjustment, thereby being beneficial to improving the driving safety and reducing the traffic accident rate.

    本申请实施例公开了一种用于高速公路的安全车距提示系统及方法,其中,该系统包括:速度传感器阵列,用于采集行车道上的前车的行驶速度V前和后车的行驶速度V后;信号控制器,用于根据前车的行驶速度V前和后车的行驶速度V后,确定后车与前车之间的安全距离L;信号控制器,还用于根据安全距离L以及后车与前车之间的实际距离S,控制地面信号灯阵列中位于后车与前车之间的地面信号灯发出相应的指示光信号。实施本申请实施例,能够通过地面信号灯发出不同的指示光信号来指示后车,以使后车及时发现异常并做出速度调整,从而有利于提高行车安全性,降低交通事故发生率。
