The invention provides an indicating device and method for directing a vehicle to pass through an expressway ETC access area at a controlled speed. The indicating device comprises a shell, and a controller, a data acquisition module and a projection mechanism are installed in the shell; the controller is connected with the projection mechanism and the data acquisition module; the data acquisition module is used for acquiring vehicle information and transmitting the acquired vehicle information to the controller; the controller is used for outputting an instruction signal to the projection mechanism, and the projection mechanism is used for outputting a projection area for directing a vehicle to pass through a highway ETC access area in a speed control manner so as to direct the vehicle to enter an ETC identification area; the projection mechanism has a plurality of projection angles and directions, the strong point light source is projected into various words after being converged through the arc-shaped reflector, passing vehicles are directed to control the vehicle speed and pass through an ETC recognition area within the limited vehicle speed range, and the situation that overspeed causes blocking of an entrance and exit of a highway and potential safety hazards are avoided.

    本公开提供了一种引导车辆控速通过高速公路ETC出入区域的指示装置及方法,包括壳体,壳体内安装控制器、数据采集模块和投影机构;控制器与投影机构和数据采集模块相连;所述数据采集模块用于采集车辆信息,并将采集的车辆信息传输至控制器;所述控制器用于输出指令信号至投影机构,所述投影机构用于输出引导车辆控速通过高速公路ETC出入区域的投影区域,以对车辆进入ETC识别区域进行引导;投影机构具有若干个投影角度和方向,强点光源通过弧形反光镜汇聚光源之后投影为多种字样,引导过往车辆控制车速,在限定车速范围内通过ETC识别区域,避免超速从而导致高速出入口堵塞,造成安全隐患。
