Queue Detect

Download product sheet

The pioneering low power Queue Detect System has been developed to help ease congestion on roads and highways.

It uses state-of-the-art Frequency Modulated Continuous Wave Radar to detect slow moving traffic which is notified to Bartco UK’s central server and activates the display of information on single or multiple mobile variable messaging signs (VMS). The message is cleared once traffic returns to the desired speed.

Flexible and effective, traffic management agencies set the content of the VMS and the speeds at which traffic triggers and clears their display.

This product can be used in conjunction with both our highly portable VMS-A and VMS-C products. Email info@bartco-uk.com to find out more.
