MORE STRAIGHT TALK ABOUT WIRELESS-WIRELESS ON/OFF MONITORING AND CONTROL BASICS FOR TRAFFIC APPLICATIONS

This article presents an overview of wireless on/off monitoring and control technology, also known as wireless contact closure. The basics of the technology are first discussed. Some of the benefits of wireless communications technology, in comparison to hardwire communications, are then identified. These include: reduced deployment costs; ease of installation; no disruption to traffic; no need for permits, inspections, or environmental studies; no problems with damaged cables or signal degradation; and, flexibility in locating system components. The article then identifies the types of traffic devices that can be enabled with wireless on/off monitoring and control. These include: detectors, controllers, pushbutton switches, flashers, and signal lights. These devices in turn can be used in applications such as traffic detectors, ramp metering systems, advanced traffic management systems (ATMS), advanced traveler information systems (ATIS), school zone and work zone flasher activation systems, and signal light preemption.
