LOOP DETECTORS | Loop detectors are coils of wire embedded in the pavement and covered by an epoxy. When a bike or car drives over it, the metal wheel electromagnetically triggers the sensor, alerting the traffic light to turn green.
To get the detector to work properly you need to position your bike over the loop, which are fortunately easy to see. The detector shown here is a bike specific loop where you want to line the bike up over the bike symbol. Many of the loops serve both bikes and motor vehicles. These are commonly circles with a diagonal line running through them. For this style place you bike across the diagonal line at a 45o angle. If it is just a circle…with no diagonal…place your bike across the edge of the loop.
Detector loops are important to signal timing as they improve the flow of traffic. Bike boxes and detectors are often used concurrently.
In areas with consistent traffic in most directions, loops aren’t as important as they are on side streets where one vehicle or bike would often wait longer than necessary.
Long Beach has thousands of loops. Typically when a new intersection is built, roadway repairs are made, or there are street upgrades, new loops are installed.
If you find a loop that is not working please let us know by going to the contact us page and sending an e-mail indicating that the signal is not work for bikes and give the location of the signal. When giving the location please be as specific as possible…for example…Vista at Redondo – East side of intersection.
