PARKING VEHICLE DETECTORS AND COUNTERS FROM TAPCO

Vehicle Detectors

Enlarge

A vehicle detection system provides an input for traffic-actuated signal control, traffic control, roadway surveillance, and data collection systems.

The inductive loop detector has become the most popular form of detection system. Inductance is a circuit element, typically a conducting coil, in which electrical current is generated by electro-magnetic flux through the circuit. The principal components of an inductive loop detector system include one or more turn of loop wire wound in a shallow slot sawed in the pavement, a lead-in cable to a gate operator cabinet, and an electronic detector unit housed in the cabinet.

When a vehicle passes over the loop or is stopped within the loop, it decreases the inductance of the loop. This decrease in inductance then actuate the detector output relay (or circuit) which, in turn, sends an impulse to the controller unit signifying that it has detected the passage or presence of a vehicle.

Contrary to popular belief, inductive loop detectors sense metal surfaces, not necessarily metal mass. Actually, the heavy metal engine in the loop area increases the inductance (because of the phenomenon known as the ferromagnetic effect). The peripheral metal - the large, flat horizontal plane of the vehicle - has the opposite effect and more than offsets the increase from the ferrous mass of the engine, and the net effect is an overall reduction in inductance.

Portable Traffic Counter/Classifier and Road Tube

Enlarge

The portable counter/classifier provides ease of use and optimal functionality to monitor inputs using loops, piezos or contact closures. With pre- programmed quick setup features, field personnel need only press one or two keys to select recording operation. The type, configuration and format of data to be collected can be custom programmed or selected from menu driven choices. Available data types include one or more combinations of per-vehicle records, per lane data, binned vehicle classification by axle, speed, length, gap, or headway.

Features

2 MB onboard memory, additional storage memory card available
Solar power option
Water-barrier airswitches and weatherproof housing

Portable Traffic Counter/Classifier and Road Tube
