MVIS’ new low power Queue Detect system uses a state of the art Frequency Modulated Continuous Wave Radar to monitor the road for slow moving traffic. Once slow moving traffic is detected the system communicates via the GPRS network with MVIS’ server, which in turn activates your desired message on any number of portable variable message signs (VMS). It can be used with both MVIS’ VMS-A and VMS-C products.
The speed at which the traffic triggers the message can be set remotely, as can the speed at which the message is cleared. The radar itself can either be mounted on an MVIS portable VMS, a Solar IP trailer or for long term deployment it can be mounted onto an existing column along with a small solar panel and battery.
