Vehicle Loop Detector

JUTAI Loop Detector  are the most commonly used vehicle detector for freeway management JUTAI Loop detectors are the most commonly used vehicle detector for freeway management. A loop detector consists of a physical loop of wire embedded in the pavement connected to a sensor located in a nearby cabinet.  The sensor detects the presence or absence of vehicles over the loop and typically allows a user to manually select the sensitivity level of operation to accommodate for a wide  range of responsiveness from the physical loop. In conventional practice, However, it is difficult to know the physical loop’s responsiveness, which makes selecting the appropriate sensitivity level difficult.  If the sensitivity and responsiveness are poorly matched it will degrade the detector’s data and the performance of applications that use the data, including: traffic management, control, and traveler information. To resolve this often overlooked problem, this paper presents ...

Loop Design Essentials /Loop wire/ Loop detector installation Proper installation of the loops is essential for reliable vehicle detection. Most vehicle detector problems are caused by improper loop installation! „ The geometry (shape and size) of the loop defines the detection zone. See the figures to the follow for typical loop geometries used for access or traffic control. „ Loop sizes may differ and will depend on lane width, traffic patterns, and types of vehicles to be detected. The following guidelines are typically used today with most access control applications: ƒ Large rectangular loops (4’ x 8’, 6’ x 8’, 6’ x 12’ are used to detect larger vehicles and high bed vehicles (trucks). ƒ Small size loops (i.e. 2’ x 5’, 3’ x 6’, 6’ x 6’) are used to detect smaller vehicles, such as motorcycles and automobiles. Important Note: Typical detection height is about 2/3 of the shortest leg of the loop. Adjacent loops operating on separate vehicle detectors may interfere (cross-talk) w...
