Paper Title
Controlling Of Traffic Signals And Vehicles At Road Junction Using Zigbee

Traffic congestion is the biggest problem faced by densely populated countries like India, China, etc. So our project focuses on three areas- Traffic density control, making path to emergency vehicles (like ambulance, patrol vehicles, etc.) and making the vehicles to stop at stop line. ZigBee based traffic control will be provided for traffic signals and vehicles. ZigBee are used to provide dynamic traffic control and thus increasing the duration of the Green light of the lane in which traffic density is high. Hence the traffic density is regulated. Thus the ZigBee communicates with the microcontroller in each vehicle crossing the lane while it was in red signal. The emergency vehicles have more priority in signal changes to creating path in that particular lane. Keywords- AT Mega 8, RF (radio frequency), ZigBee.
