A novel battery-less wireless traffic sensor has been developed that can provide both real-time measurements of traffic flow and weigh-in-motion measurements.
The sensor consists of a thin, beam-like device embedded in the road pavement and a remote transceiver that receives wireless signals from the embedded device. The embedded device is inexpensive, requires no wiring, and consumes zero energy. It operates by harvesting energy from the vibrations induced by the passing of a vehicle over the sensor location.
This seminar presents the design of the sensor, development of associated control algorithms and electronics, and experimental results from vehicle tests.
Rajesh Rajamani is a professor of mechanical engineering at the University of Minnesota. His research interests include vehicle dynamics and control, intelligent transportation systems, microsensors, and control system design. In addition to development of battery-less wireless traffic sensors, his current research activities in transportation include the development of a novel narrow tilt-controlled commuter vehicle, development of systems for real-time estimation of tire-road friction coefficient on highway vehicles, and development of electronic stability control systems.
