The Minnesota Traffic Observatory (MTO) is a transportation laboratory focusing on the testing and evaluation of new transportation management and operational strategies and traveler information technologies. The MTO is a facility of the University of Minnesota's Department of Civil, Environmental, and Geo- Engineering. It is also affiliated with the Roadway Safety Institute, the Region 5 University Transportation Center.

CTS: Celebrating 30 years of innovation
In celebrating its first 30 years, the Center for Transportation Studies is looking back at research, education, and engagement highlights to illustrate the innovation that makes transportation better. Traffic operations is a great example of how U of M research meets practical needs. Autoscope® technology, invented at the U of M, was commercialized in 1991. Current research at the Minnesota Traffic Observatory builds on this legacy. A short video celebrates three decades of innovation in traffic operations.

Move over one: Determining the effectiveness of ILCS in Minneapolis
Minnesota’s Smart Lanes is the brand name of the active traffic management (ATM) system implemented on I-35W and I-94, the two busiest freeways in the Twin Cities of Minneapolis and Saint Paul. The centerpiece of this system, and a novel idea at the time of its installation since no other U.S. city has anything similar, is the implementation of Intelligent Lane Control Signs (ILCS). Minnesota Traffic Observatory director John Hourdos explains.

Deadly crash highlights danger of left turns
Research shows left-turning vehicles are more likely to be involved in a collision, because the vehicle must cross in front of oncoming traffic.... Experts say that while there are some steps that can be taken to reduce the hazards, such as better road design and alert drivers, turning left is just inherently more risky. "They are the most dangerous because they are direct conflicts between different movements," said John Hourdos, director of the Minnesota Traffic Observatory and an adjunct assistant civil engineering professor at the University of Minnesota.
