Vehicle traffic control is recognized as an effective way to relieve mounting traffic congestion in large urban areas across the country. The most common method of vehicle detection is in sensing a change in inductance through the use of wire loops buried beneath the road surface. DVP, Inc. has just completed the development of an advanced digital instrument specifically designed for IL detection, testing and characterization. The advantage of a digital instrument is that a series of precise measurements can be made with a single data acquisition and processing system. Digital technology enables implementation of clearer display formats, storage and hardcopy of measurement data, remote control interfaces, etc.
