Nowadays the drivers drive vehicles at high speed even in speed limited areas without considering the safety of the public. Many accidents are taking place frequently due to the small mistakes while driving in school zone, hospitals, hills area, and highways result in loss of many lives. Therefore, in order to avoid the accidents and to alert the drivers for controlling the speed of the vehicle, ZigBee based Tree Routing algorithm is proposed. ZigBee technology gives the alert signal to the driver about the zones with the help of buffer and limits the speed of vehicle. ZigBee based routing algorithm is established in the form of mesh network for transferring the information between two or more vehicles. Here, GPS circuit is considered for tracking the longitude, latitude, distance travelled, direction of travel and time. Whenever the vehicle is crossing a particular region with a certain speed, the GPS feeds the signal to the processor. When the vehicle speed exceed beyond the limit, the speed sensor is used to control the speed at the specific location automatically. In addition, Alcohol sensor is placed in a vehicle to identify whether the driver taken liquor or not. ZigBee is a wireless communication protocol which has the characteristics of low power consumption, low cost and self organizing features.
