Traffic detection events are signalled from VDS to the TS2 controller in conformance with the NEMA TS2-2003 specification and using FlexConnect and eliminates the need for interface cards without requiring available slots in traffic signal cabinets. The unit supports 64 channels arranged as four racks of 16 channels each (the status of each channel can be displayed on an LED screen on the front panel) and the compact unit can be mounted anywhere in a traffic signal cabinet.
FlexConnect includes a mode that monitors the signal phase data that can be fused with the vehicle detection data to generate 24×7 intersection performance measures which can be used to optimise signal timing, reduce arterial congestion and improve intersection safety.
