We currently maintain over 400 intersections throughout San Diego County for 8 different Public Agencies. Our signal technicians are on call 24 hours a day to keep the signals functioning properly. We perform everything from preventative maintenance to installation of complete intersections.
A traffic loop detector is a sensor found at intersection, parking lots, driveways, in which a circular cut is made with a saw in the roads surface, wire is wrapped around the loop cut, back to its source and sealed. As a car approaches a traffic signal It senses the cars magnetic field and tells the intersection controller there are cars waiting to go.
