The IntelliZone AdvanceWarn System incorporates traffic monitoring sensors, weather sensors, and pavement condition sensors, to update motorists using Highway Advisory Radios (HARs) and portable message signs. The result is a completely integrated advanced warning system that monitors current conditions and informs motorists of hazardous weather and traffic problems.

The AdvanceWarn system collects data from the traffic sensors, pavement sensors and atmospheric weather sensors. The system analyzes real-time data and, when conditions warrant, updates messages on the HARs and portable message signs along the roadway. These updates are in real time, to provide time critical hazardous weather and traffic conditions to motorists.

The IntelliZone Dynamic Detour Alert System is designed to inform motorists when they should use an alternate route, providing information about expected delays and travel times. This system utilizes traffic sensors, dynamic message signs, HARs and flashing beacon systems.

The system retrieves data from traffic sensors, calculates the travel time delay, and updates the dynamic message signs, HARs, and flashing beacons to reflect the current conditions. If the travel delay exceeds a user-defined limit, motorists traveling in either direction are informed of the delay and detour information is provided.

The IntelliZone Active Warning System (AWS) incorporates data from a non-invasive pavement sensor to activate flashing LED border signs. The IntelliZone AWS monitors the data outputs from the Lufft NIRS31 non-invasive pavement sensor every 60 seconds and when conditions warrant automatically updates the flashing LED border signs. The result is a completely integrated active warning system that monitors current roadway friction conditions and informs motorists via flashing LED border signs of hazardous surface conditions.

The IntelliZone Bridge Deck Warning System (BDWS) incorporates a combination of atmospheric RWIS data and pavement sensor data to activate flashing beacons and/or flashing LED border signs. The IntelliZone BDWS analyzes multiple data inputs including air temperature, dew point temperature, bridge deck temperature, freezing point, surface status, precipitation type/rate and surface friction to determine whether to activate the flashing beacons and/or flashing LED border signs.

The result is a completely integrated bridge deck warning system that monitors current atmospheric and roadway conditions and informs motorists via
flashing LED border signs of hazardous travel conditions.
