The objective of this paper is to provide a brief description on the proposed technologies to predict the collision between vehicles before the collision. The spectacular increase in traffic increases the demand for innovative technologies that can improve the safety and efficiency of transport systems. Road safety can be significantly improved by the use of wireless communication technologies for vehicle networks, which allows new services such as collision detection traffic management and other communication devices between moving vehicles. This paper presents an implementation of the complete vehicle-vehicle communication based on Li-Fi technology and DSRC technology based on Wi-Fi. The proposed system solves many of the problems faced by existing systems by using a GPS module instead of the conventional speedometer and also uses sensors that are reliable in areas where human intervention is involuntary or life-threatening in danger of extinction. The problems of congestion in the urban arteries increase day by day, and it is very difficult to deal with them in emergencies. Therefore, within the system, a communication unit is developed that interacts with other vehicles to free the lanes. This system aims to communicate with the vehicle in its environment using its location (i.e., using latitude and longitude) to indicate proximity. If these vehicles are in the immediate vicinity, drivers are notified by a message. In this way, drivers can communicate with each other and act according to the situation.
