Road Tubes: More Than Just A Number These pneumatic road tubes are primarily used for traffic counting, although they serve many more purposes than just counting.3.
These unassuming devices are multi-dimensional data collectors that are essential to improving our road system and maintaining efficient traffic flow.
The working details of these tubes are clarified by the U.S. Department of Transportation. An air pressure burst is produced when a car’s tires pass over the rubber tube;
This closes an air switch and sends an electrical signal to a counter device. Each of these tubes has a different function and may be installed either permanently or temporarily.
While permanent configurations enable constant, in-depth monitoring, temporary configurations, which sometimes last just a day or two, give brief views into traffic dynamics.
These black wires are placed by transportation authorities in low-interference locations, primarily on straight sections of road to maximize data collecting. Agencies are able to measure
