TMS-QD
The TMS-QD detects the formation of slowdowns and the return to regular traffic flow, based on the number of vehicles and their average speed.
Easy to install, it is particularly suitable for motorway exit ramps. It is connected to a warning panel to initiate a “queue in formation” alert message or indicate a load-shedding route.
Operation and stengths
This Doppler radar has a relay output and can be configured via an RS-232 serial link.
The radar has a “traffic jam” counter and a “fluid” counter. Each counter is associated with a threshold, a speed and a timer.
When a number of vehicles greater than the value determined for the “traffic jam” counter and running at a speed below the determined threshold has been measured during the selected interval, the “traffic jam” relay is activated. When the “fluid” values are reached, the relay is released.
The radar is non-intrusive. Simple and quick to install, it works in all weather and light conditions.
