University of Minnesota develops warning system

Traffic Technology Today, October 18, 2013

To help drivers pay more attention in work zones, researchers from the University of Minnesota developed the Intelligent Drum Line (IDL) system prototype. The portable, dynamic warning system project was led by John Hourdos, director of the U of M’s Minnesota Traffic Observatory, and sponsored by the Minnesota Department of Transportation (MnDOT).

Experts say more I-94 lanes from Twin Cities to St. Cloud not best fix for congestion headache

StarTribune, October 13, 2013

Solving chronic traffic congestion on Interstate 94 between the Twin Cities and St. Cloud is not likely to be as simple as adding additional lanes. Some political leaders have supported that approach as a solution to chronic backups, particularly in stretches closer to the Twin Cities. But the St. Cloud Times reported Sunday that engineers and traffic experts say it’s not that simple, and could even end up making bottlenecks worse.

No quick fix for busy I-94 through Central Minnesota

St. Cloud Times, October 13, 2013

Is solution to congestion more lanes, user fees or improved transit? Adding another lane to Interstate Highway 94 between St. Cloud and the Twin Cities may seem like an obvious solution to the traffic backups that often frustrate motorists. But engineers and transportation experts say it isn’t that simple to ease the flow of vehicles in one area without causing problems somewhere else. Adding another lane is not only expensive, it wouldn’t solve the congestion and could even make the bottleneck near the Twin Cities worse.

MnDOT deploys iMonitor software

Traffic Technology Today.com, August 1, 2013
SMART Signal Technologies has installed its new iMonitor software system on 52 intersections for the Minnesota Department of Transportation (MnDOT), which is intended to improve traffic signal performance along the Twin Cities (Minneapolis-Saint Paul) congested signalized arterial corridors. Using patented technology licensed from the University of Minnesota, the iMonitor system is less expensive than the cost of installing new controller cabinets, which are used to regulate phase changes at signalized intersections.

New warning system may make rural intersections safer

WDIO-TV News, July 30, 2013
A team in Duluth is testing a new warning system that could make some rural intersections safer. It’s a wireless, solar-powered system that will alert cars if there are other vehicles approaching the intersection. It’s the first of its kind in Saint Louis County. Researchers also sent out about 200 surveys to people who live close to the intersection. UMD Research Assistant Husam Ismail said 90 percent of the feedback was positive.Continue reading


GPS devices may not be all that accurate

StarTribune, July 27, 2013
Turns out the digital era hasn’t saved the directionally challenged. Despite high-tech GPS devices, we still get lost. Max Donath, director of the University of Minnesota’s Intelligent Transportation Systems Institute, has devised his own solution: “I carry four or five GPS apps on my phone. I switch from one to the other if one of them gives me grief.”
