NEWS™
NEWS™ (Node Event Warning System) is designed to detect and send warnings of traffic irregularities (stopped traffic, etc.) to drivers by variable message signs, flashers, and other warning signals. Using your specified criteria for up to 16 pre-programmed events, the system monitors up to 8 stations and provides immediate alarm output. Perfect for both permanent and temporary installations, it is fast and easy to deploy and reliable in all weather conditions.
The system performs real-time processing of traffic measurements from multiple RTMS® units and provides alarm output based upon user-defined pre-programmed events. Outputs include contact pair closure (to drive dumb devices) and serial bus messages for VMS display and to alert traffic operation center operators.
Applications
- Queue detection/alarm
- Early warning on pre-programmed safety related events
