Driving on roads nowadays has a lot of limitations. Traffic congestion is increasingly happening especially at the urban areas because of the increasing population & urbanization. Accordingly, the traffic flow is not being run properly (vehicles delay & traffic congestion) and reduces the throughput at the intersections. In this paper, We suggest a system architecture serving as Intelligent Transportation Systems (ITS) to overcome the road limitation resultants. The proposed system design, Initially, has five main devices which would co-operate together to provide safety, assistance, and comfort for the drivers. By applying this system on roads, researcher would have an opportunity to create more protocols and algorithms improving traffic flow, safety, and comfort of driving. A chosen application (Improving intersection traffic flow) 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. © 2011 IEEE.
