Traffic counter

Traffic counter

A traffic counter is a device, often electronic in nature, used to count, classify, and/or, measure the speed of vehicular traffic passing along a given roadway. The device is usually deployed in near proximity to the roadway and uses an intrusive medium, such as pneumatic road tubes laid across the roadway, piezo-electric sensors embedded in the roadway, inductive loops cut into the roadway, or a combination of these to detect the passing vehicles. Recently, in the interest of worker safety and ease of installation, non-intrusive technologies have been developed [cite web|url=http://www.dot.state.mn.us/guidestar/nitfinal/part1.htm|title=Field Test of Monitoring of Urban Vehicle Operations Using Non-Intrusive Technologies|accessdate=2006-06-20|format=HTML|publisher=Federal Highway Administration|month=May|year=1997] . These devices generally use some sort of transmitted energy such as radar waves or infrared beams to detect vehicles passing over the roadway.
