Road intersections represent one of the most complex configurations encountered when traversing road networks. A high percentage of accidents occur at these locations. In- addition increasing number of vehicles makes the number of accidents and collisions increase in a dangerous way specially in high way roads, many researches on that topic has been made on the recent technologies to reduce the number of accidents, if we come up with a way that enables cars to communicate with each other, and each car sends data about it, such as its location, speed and direction in which it will travel, this will facilitate movement and reduce collisions. In this research paper, we will propose to present communication protocols between cars and each other through intersections, as well as between cars and the surrounding environment, through short-range wireless communications that coordinate movement between cars and prevent collisions.
