Wisconsin award-winning project deploys RTMS G4 

The new-generation RTMS G4 radar detector, being exhibited by ISS (Booth 929) used on the huge Marquette Interchange Project in Milwaukee, Wisconsin for queue detection, ramp metering and mainline vehicle detection. The $810 million project involves completing 28 ramps and 21 miles of roadway.

The project went live last May; the detectors monitor traffic flow, handle ramp metering and feed information into the area's travel time prediction system.

A major advantage of using the RTMS sensors, said Mike Ouellette, ISS's vice-president sales, North America, is that they use existing infrastructure, such as roadside poles and sign structures, with no need to cut loops: "It's a non-intrusive way to acquire traffic data."

Brian Scharles, manager of technical services for TAPCO, the company responsible for deploying the sensors, commented: "The new RTMS G4 detectors were extremely easy to deploy and we were able to place the sensors at locations where other model detectors would not operate."

This is the first time that RTMS products and Autoscope products have been exhibited together since ISS acquired EIS in December 2007.
