Alternate Thinking: A New Order in Detection Networks

This article provides a rundown of current Advanced Traffic Management Systems (ATMS) and their data needs in the context of a new detection technology that could be more feasible under some conditions than loop detectors, which are currently the most frequently used technology. Among the applications served by detection systems are traveler information systems, adaptive signal control, and corridor management. While radar and video technologies have been developed to address the shortcomings of inductive loops, which are subject to damage and resulting unreliability, these systems have difficulty providing accurate data that can support a densely traveled corridor. They are also costly to maintain and operate properly. A new wireless magnetometer vehicle-detection system uses small plastic units that are installed in the center of the lane, thereby avoiding much of the wear and tear suffered by loops, and send their data in real-time via wireless communications. They are powered by batteries that have a working life of at least 10 years, and the units do not require trenching to be installed.
