Multi Agent Protocol for Cooperative Rear-end Collision Avoidance System

The development of communication between vehicles allows the development of a safety system based on cooperation. Through the cooperation of one vehicle with another vehicle will work together to improve the level of traffic safety. On toll roads, high-speed and sequential vehicles have the potential to experience rear-end collisions and multi-vehicle collision (pileup). Delay in braking from vehicles behind a vehicle that brakes suddenly is the main cause of a multi-vehicle collision. The braking delay is greater if the vehicle is further away from the vehicle which is the cause of a multi-vehicle collision. Through V2V communication, braking by a vehicle can be notified to other vehicles far behind it. This will speed up the braking response so that multi-vehicle collision can be avoided or reduced impact. Devices used to avoid rear-end or multi-vehicle collision in a cooperative manner are recognized as Cooperative Rear-end Collision Avoidance System (CRCAS). The device is part of Advanced Driver Assistance Systems (ADAS) and is a refinement of RCAS. This study discusses the protocol used by vehicles to communicate with each other and cooperate to avoid a rear-end or multi-vehicle collision.
