Traffic Congestion has become a major problem for urban areas. It would occur according to the road limitations and the technologies used on road and intersections. Accordingly, the traffic flow is not being run properly (vehicles delay & traffic congestion) and reduces the throughput at the intersections. We are taking the opportunity of using Intelligent Transportation Systems (ITS) to overcome the road limitation resultants. We are proposing a system design with its protocol and set of algorithms to help balancing the road traffic load and make the driving on highways and urban cities roads more comfort. Initially, the system has five main devices which would co-operate together to provide safety, assistance, and comfort for the drivers. By applying this system on roads, we expect to see an easy traffic flow and more efficient and comfort driving. Chosen application results were obtained from simulation studies, are compared with our system to show the significance or the need for the proposed system and its protocol's control actions and strategies. The paper concludes with a brief discussion of future needs in this important technical area. © 2011 IEEE.
