Abstract
Hilly areas with winding and curved roads pose significant challenges for vehicle navigation, particularly in situations where visibility is limited. The problem becomes more pronounced at night or during adverse weather conditions. To address this issue, we propose an innovative solution using visible light communication (VLC) for collision avoidance. VLC technology can provide real-time communication between vehicles and infrastructure such as traffic lights, road signs, and roadside beacons, which improves situational awareness and enhances road safety. This paper discusses the design, implementation, and evaluation of a VLC-based collision avoidance system for vehicles navigating curved roads in hilly terrains. With a transmission power of 0.5 W, the system achieves an acceptable BER of less than 10−9 up to 32 m, ensuring reliable short-range collision avoidance. Increasing the transmission power to 1 W extends the communication range to 38 m, maintaining the same BER. We demonstrate how VLC can effectively mitigate the risks of accidents due to limited visibility, providing a safer driving experience for motorists in challenging environments.
