DESIGN AND DEVELOPMENT OF THE WIRELESS SENSOR NODE FOR TRAFFIC FLOW SURVEILLANCE
ABSTRACT
Wireless sensor network is expected to be deployed in intersection to monitor the traffic flow continuously, and the monitoring data can be used as the foundation of traffic light control.
In this paper, a traffic information and transmission system based on Zigbee and wireless sensor network is built, and the sensor nodes used in traffic flow surveillance are developed. Structure, hardware and work flow of WSN nodes are designed.
The stability experiment and the actual environment experiment are carried out in the last of the paper. The results of experiments show that WSN has the ability to collect traffic flow information quickly and transmit the datum to the processing center in real time.
