Traffic counter (UTMC-compliant)

Combine with inductive loops or other detectors to create a UTMC-compliant counting solution for car parks or on the highway

Product Overview

IDT's fully UTMC-compliant car park counter will collect data from inductive loops cut into the entrances and exits of car parks and send that data to a UTMC-compliant Common Database.

If inductive loops are not available then the counter's opto-isolated inputs will accept inputs from other vehicle detectors such as TrafiCam® or Heimdall® detectors.

Car parks with multiple entrances/exits are supported using either secondary counters or remote loops connected via meshI/O. Our counters have been deployed with all available UTMC Common Databases - please contact us for further information.

Features and benefits

IDT's car park counter presents data via its ethernet (RJ45) port on the front. This means it can use any available IP communications link such as a corporate LAN, a nearby iMesh link or i3G router (for example, if you have a UG405-compliant UTC junction in the vicinity).

A typical solution using IDT's car park occupancy counter is shown below. This drawing shows a UTC instation communicating with a car park counter (bottom right) which is counting cvehicle movements via two inductive loops.  The car park counter is in a cabinet together with one of IDT's GPRS routers. The UTMC common database requests data periodically from the counter (the interval is set by the system operator at the instation).

The instation processes the count data along with information obtained from other datasources in the UTMC system such as air quality monitors and UTC. By following strategies at the instation (such as car park fill rates, congestion at specified junctions), system managers can set messages on the variable message signs (shown top right).

Because the system is fully UTMC-compliant it can use our counters along with VMSs from several suppliers - all inter-connected with a communications network independent of the end devices. In the example above the sign has a GPRS router but it could equally use an iMesh router to connect to a nearby traffic signal controller without any changes required to the sign.
