Illinois Tollway Ramp Queue Detection

Description

Traffic backing up on an off–ramp and onto the main line is dangerous and reduces capacity. Ramp queue detectors will monitor for traffic backups and allow the agency operating the arterial traffic light to clear the ramp. This is currently in operation on Army Trail Road at I–355, NB Tri–State Tollway at Illinois Route 132, WB I–88 at Farnsworth Avenue, and EB on the Edens Spur. Tollway ramp devices initiate an alarm at the DuPage County Division of Transportation (DDOT) office and activate a pre–installed timing program in the Aries signal controller software, designed to clear ramps of queued traffic prior to having traffic back up onto the through lanes of the expressway. Illinois Tollway uses detection and other signage to support traveler information and awareness. The goal is to implement this capability at all major interchanges.
