Development of Portable Wireless Sensor Network System for Real-Time Traffic Surveillance

摘要

Wireless sensor network (WSN) technology is rapidly maturing and gaining momentum as an enabling technology for Internet-of-things, and Intelligent Transportation Systems (ITSs). This paper introduces the design of a novel, cost-effective intelligent vehicle counting and classification sensor system. Distinctive algorithms for vehicles detection, counting, and signature re-identification were developed and integrated. The system's integration of wireless communication, smart sensors, and intelligent algorithms is discussed in detail. Various experimental analysis scenarios are reported. A preliminary experimental study resulted in 98% accuracy for counting and detection. After system improvement in detecting class 9 vehicles by analyzing the inter-arrival time, detection accuracy reached 100%. Estimated cost of the proposed system is less than $40.
