Abstract: This paper focuses on the development of a portable roadside magnetic sensor system for vehicle counting, classification, and speed measurement. This paper describes a portable sensing system that can be placed adjacent to a road and can be used for vehicle counting, vehicle classification, and vehicle speed measurements. The proposed system can make these traffic measurements reliably for traffic in the lane adjacent to the sensors. The developed signal processing algorithms enable the sensor to be robust to the presence of traffic in other lanes of the road. Project proposed to add RFID device for vehicle classification.
