JUTAI Loop Detector are the most commonly used vehicle detector for freeway management

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 ...

LD-102 Parking Loop Sensor Vehicle Fast Speed Detector Gate Openner Detailed Product Description JUTAI vehicle loop detector operates on the principle of inductance. the jutai loop detector drives energy through the detection loop at a frequency between 20 to 2000 uH, to creat an electro magentic field. JUTAI vehicle loop detector suitable for parking, Highway Toll Station and traffic signal control, etc. The detector is a single channel detector, which only can simultaneously monitor an inductance coil. It has two relay to output signals, so the user can choose different output signal to control the mechanical drive, the card device or vehicles counting. Technical Parameter for single channel vehicle detector Technical Parameter for single channel vehicle detector Self-turning range 20-2000uH Response Times 10-90MS Sensitivity 16 way selectable levels Visual Indications Power LED-Red, Channel LED-Green Frequency Four step switch, selectable 20-80KHz Relay time 0,2,4,8,...

Vehicle detection loops: automatic your access control point

图片
Vehicle detection loops: automatic your access control point  Detection loops are typically installed in roadways with security barriers or traffic gate to detect the presence of a vehicle to provide an indication as to a vehicle's presence within the barrier area. This indication is to help prevent the barrier or gate from closing while a vehicle is present. Some loops also provide i nformation to control the barrier's movement. The type of barrier ( barrier gate, bollards, rising beam, drop arms, swing gates, sliding or track gates, traffic arms) and its intended use, should determine which loop function should be used and where they should be located. All loop functions should be a part of an overall traffic flow theory of operation for the particular access point, to ensure proper operations.
