Traffic Safety

Improving the safety of transportation networks is a key area of research at the Minnesota Traffic Observatory. The MTO’s ability to gather fine-grained data on traffic dynamics has driven significant research into the causes of vehicle crashes and potential countermeasures. In addition to studying crashes and dangerous traffic conditions, the MTO provides support to researchers seeking to understand how the design and construction of road networks affects safety and mobility.

Featured Project: Effect of Signing and Striping on the Safety of a Two-Lane Roundabout


In this project, MTO researchers examined driving behavior and safety before and after signing and striping changes were applied at a two-lane roundabout in Richfield, Minnesota. Researchers analyzed crash records and examined hundreds of hours of video to compare the crash rates and number of violations committed by drivers before and after the changes.
