An approach to establishment of cars to road management system

Traffic accidents have recently become a significant terror for all members of the community, their contribution to the cause of death and huge economic losses have become very large, this is due to the violation of the traffic rules and exceeding the speed limit for the road by the drivers. The main objective of this study is to improve the traffic flow to overcome these problems. The methodology used in this study is to design a communication system between the road and the car to alert and control the speed of the car wirelessly via XBEE; it consists of a two transceiver module. The device is fixed at Pre-determined position send the speed limit and gives notes about general facilities of the road like the word “emergency” to inform the drivers that there is an ambulance, this alert appear in a form of messages which displayed on the Liquid Crystal Display LCD. The other device is fixed on the car that received these messages wirelessly, and then displays it on the LCD. The result obtained from this study is by calculating the number of Revolution Per Minute (RPM) for a motor is 460 rpm, therefore the maximum speed of the car is 450 kilometers per hour for cars with the wheel radius of 26 cm. The programs used for simulation are Proteus, arduino software and visual basic.
