Low cost and power efficient automated traffic control system using IEEE 802.15.4

The paper discusses a proposed model for automated traffic signal control system using short range wireless technology standard IEEE 802.15.4 (ZigBee). The proposed model is expected to be low cost and power efficient which is well suited for Transportation and Surveillance Systems in developing countries. Several experiments were performed to gauge the efficiency of ZigBee technology in open environment like roads where various hurdles can affect the communication; however, results were very encouraging and showed that although ZigBee is a short range wireless technology but it is well suited for transportation systems using multi-hop communication. This paper specifically deals with the wireless communication between various ZigBee modules and studies the effect of various factors on ZigBee communication in open environment.
