Weather Taking Its Toll On Vehicle Detection Equipment
01-07-2011
A vehicle detection loop at the intersection of Xenia Ave and Golden Hills Dr is malfunctioning and causing added delays for drivers on Xenia Ave. Maintenance crews have been notified of the problem and will be out to fix it.
Vehicle detection loops are used for more effect traffic signal operation. The detectors send a signal to the signal controller when a vehicle passes over them. Once the signal is received, the traffic signal either gives the vehicle more green light time or starts the process of changing the light from red to green.
Detection wires are installed by making cuts into existing pavement. These cuts are sealed, but water can still leak in. When water seeps into the cuts and freezes, it can damage the wires. The rainstorm the last week of December, followed by the cold temperatures in January, created prime conditions for damage to detection loops. Currently, only the Xenia Ave /Golden Hills Dr intersection has been observed to have a detection loop problem.
