More than five years ago, U of M researchers studied a group of new teen drivers to gauge the effects of real-time, in-vehicle coaching with their innovative Teen Driver Support System (TDSS) smartphone application. Now, a follow-up study offers new understanding about the system’s long-term effectiveness in reducing risky driving behavior.

Connected Automated Vehicles (CAV) are part of tomorrow’s transportation future happening today. The evolution of vehicle technology is shifting how drivers interact with the infrastructure around them. Local agencies are beginning to respond and anticipate these changes, while CAV manufacturers request to test their vehicles on local roadways further pushing the urgency on local agencies.

Speeding is one of the top 5 factors in crashes in Minnesota. Prioritizing the most effective methods to encourage safe speeds is critical to maximizing effort and funding to reach zero deaths on our roadways.
In 2019, legislation passed to allow Minnesota cities to establish speed limits for city streets under the city’s jurisdiction without conducting an engineering or traffic investigation.

Flashing yellow arrow indicators have been deployed at many signalized intersections in recent years to control left-turn movements and improve traffic flow.
When illuminated, the flashing yellow arrow allows waiting motorists to make a left-hand turn after yielding to oncoming traffic.
The Federal Highway Administration considers flashing yellow arrows to be a significant safety improvement over traditional yield-on-green indicators, which are believed to be less intuitive. However, motorist complaints and some high-profile crashes indicate that there is still some level of driver confusion.

Many of us would never drive after drinking, but we’re not as hesitant about getting behind the wheel after being awake for too long or not getting enough sleep. It turns out that can be just as dangerous as driving while impaired by alcohol or drugs.

A newly developed system helps traffic engineers quickly spot failing loop detectors, which are used to monitor traffic volumes on Minnesota highways. The software program, developed by the University of Minnesota-Duluth for the Minnesota Department of Transportation, evaluates loop detector data and reports current loop detector health in an easy-to-read graphic format, making it easy to identify loop detectors in need of repair and which loop detectors should be used for the most accurate traffic counts.
