In this paper, an innovative and smart Visible Light Communication (VLC)-based Intelligent Transportation System (ITS) is designed. The proposed system uses vehicle LED headlamps as a remote controller. Differential Pulse Position Modulation (DPPM) is utilized for the sake of its asynchronicity. The system features an innovative optical interference cancellation mechanism to address the unwanted variable DC component and AC line noise in the received signal. The feasibility of the proposed system is demonstrated experimentally in day and night conditions using an off-the-shelf LED headlights. The Bit Error Rate (BER) performance of the system in terms of angular position of the vehicle with respect to the VLC receiver at different link ranges is evaluated. The prototype successfully demonstrates the smart control over the barrier gate using the ATmega microcontrollers family for the outdoor environment. BER of lower than ${10}^{-3}$ is achieved for a maximum link range of $4.4$ meters.

本文设计了一种创新的，基于智能可见光通信（VLC）的智能交通系统（ITS）。拟议的系统使用车辆LED大灯作为遥控器。由于其异步性，使用了差分脉冲位置调制（DPPM）。该系统具有创新的光学干扰消除机制，可解决接收信号中不需要的可变直流分量和交流线路噪声。使用现成的LED前灯在白天和晚上的条件下通过实验证明了该系统的可行性。评估了系统在不同链路范围内相对于VLC接收器的车辆角位置方面的系统误码率（BER）性能。该原型成功演示了使用ATmega微控制器系列在室外环境中对障碍门的智能控制。BER低于${10}^{--3}$ 达到最大链接范围为 $4.4$ 米。
