Collision Avoidance system in vehicular adhoc network utilizing dichotomized headway model

In vehicular adhoc network (VANET), the collision Avoidance (CA) system is an emerging technology among scholars and vehicular industries in recent years. The wireless CA system is transfer emergency message to drivers before they reach accident zone on the highway. Use dichotomized headway model, the braking model, and greenberg's logarithmic model to make vehicular mobility traces. In this paper proposed an analytical model for warning message through Collision Avoidance system. The main concern is using minimum Roadside Units (RSUs) reduce the delay while transfering the warning message from one vehicle to another vehicle. Greenberg's logarithmic model presented vehicular mobility traces and vehicle speed density. CA system transfer periodic messages to driver frequently and our model useful for future Intelligent Transportation System (ITS).
