Image Sensing systems reduces Wisconsin travel times

April 14, 2023

Image Sensing Systems will be highlighting how its RTMS Echo is part of the technology used in the Wisconsin Department of Transportation’s first flex lane on the Madison Beltline in Dane County. The flex lane is an innovative solution to ease backups during the busiest times and provide reliability for motorists. The Echo monitors the traffic volume on the highway's mainline lanes. When traffic levels hit a certain volume threshold, a notification is sent, and the system automatically opens the median shoulder lane to allow vehicles to start using the lane. The additional lane is typically used during weekday morning and afternoon rush hours. Since the Flex Lane has been in use, travel times have reduced on average by 45% and drivers have noticed less congestion and traffic backups on the Beltline.

Intersection collision avoidance system trial

Although much of the emphasis of research into intersection management has tended to concentrate on the needs of urban locations, there remain specific issues pertaining to rural intersections which need to be addressed. Here, Rebecca Szymkowski and Greg Helgeson, Wisconsin DOT, Todd Szymkowski, University of Wisconsin-Madison, and Craig Shankwitz and Arvind Menon, University of Minnesota detail progress on an intersection collision avoidance system for more remote locations.

Mounting benefits of dynamic tolling project

Wisconsin's four-year HOT lanes pilot project, launched in May 2008, cost US$18.8 million to construct. Halfway into the project, which uses variably priced, or dynamic, tolling to improve highway efficiency, the benefits are mounting. The problem was obvious, and frustrating, to anyone who ever sat in bumper-to-bumper traffic on State Route 167 and watched a lone car whiz by every 20 seconds or so in the carpool lane. But for planners at the Washington State Department of Transportation, the conundrum was
