1- and 2-axis magnetic sensors
ABSTRACT
In this paper “innovative new research topics” proposal was to investigate the potential of a vehicle detection system that combines an acousticor magnetic sensor, a microprocessor, a radio, and a battery. If such a system is feasible, it would be a low-cost, flexible alternative to loop detection systems. The wireless sensor system could be installed in a few minutes, without the expensive loop installation that requires cutting the pavement, power and loop cabling, and extended traffic disruption. Four tasks were proposed: (1) detecting a stationary vehicle, (2) detecting a moving vehicle, (3) detecting a string of vehicles, and (4) developing a networking protocol. Successful completion of these tasks would constitute evidence that the concept is worthy of further research and development effort.
