Abstract-The proposed design is based on an traffic controlling, which allow high priorities vehicles like ambulance. Each ambulance is configured with zigbee module (placed at a predefined location). In this module PICAT89C52 system-on-chip module uses to read the ZIGBEE module attached to the vehicle. It recognizes the time span of green light of respective path. As the ambulance is heading toward the junction, the green signal will turn ON. The signal will turn ON by communication with the traffic controller which is placed at junction. With the help of Zigbee modules and PICAT89C2051, System on chip wireless communication takes place between ambulance and traffic controller. The module is tested and the experimental results were found is expected.
