A quick reference guide is now available to help local agency planners and designers select the best bicycling facilities for their system. This guide walks local agencies through the selection and design process, and directs users to specific places within design manuals for details on facility questions.Continue reading Local Guidance for Bicycle Facility Design
In a recent research project, MnDOT sought to validate a smartphone app designed to guide pedestrians who are blind or visually impaired through signalized and unsignalized intersections. The project succeeded in showing the app’s effectiveness in tests at six intersections in Stillwater, Minnesota.Continue reading Smartphone App Gives Crossing Guidance to the Visually Impaired
In collaboration with the Advocacy Council for Tribal Transportation and other tribal members, University of Minnesota researchers monitored 10 roadway sites specified as safety risks for pedestrians on four rural Minnesota reservations. Analysis of videos and group brainstorming produced a shortlist of potential countermeasures that could be incorporated into future highway projects.Continue reading Understanding Rural Pedestrian Travel Behavior and Safety Issues
Due to rising fuel costs and environmental impact, consumers are increasingly aware of fuel efficiency (MPG) in the vehicles they purchase, which is reflected in increasing hybrid and electric vehicle sales. A major source of fuel consumption is acceleration and deceleration cycles caused by stopping at red lights—acceleration from a full stop requires significant power.Continue reading New Project: Cost/Benefit Analysis of Fuel Efficient Speed Control Using Signal Phasing and Timing Data
Complete streets is an approach to road planning and design that considers and balances the needs of all transportation users.
Richfield, Minnesota, located south of Minneapolis, began a Complete Streets redesign in 2013. So how did it turn out? A retrospective study has found that while construction impacts remain on the minds of business owners and residents, Richfield’s program has improved community life and traffic times citywide. Safety and multimodal use are expected to improve.Continue reading Richfield “Sweet Streets” Improve Quality of Life, Traffic Times Citywide
Roundabouts reduce the severity of crashes at intersections, but transportation agencies have received some feedback from pedestrians indicating that roundabouts, especially larger multi-lane roundabouts, can be difficult to navigate.Continue reading New Project: Pedestrian User Experience at Roundabouts
How well do the stop lines at stop-controlled intersections actually work as a safety feature? Through an extensive safety study and a before-after field observation, a recent Minnesota Local Road Research Board study showed that the assumed safety effects of stop lines as a means of influencing driver behavior are not well supported by the evidence.Continue reading How Well Do Stop Lines Work as a Safety Feature?

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.Continue reading Smartphone-Based Coaching for New Teen Drivers May Offer Long-Term Benefits
A northern Minnesota mining byproduct could provide a more affordable option for a highly effective, but expensive pavement safety treatment called High Friction Surface Treatment (HFST), and help expand its usage across the state.Continue reading New Project: Taconite as a Lower Cost Alternative High Friction Surface Treatment for Low-Volume Roads in Minnesota
With increasing traffic volumes and greater restrictions on placing road tubes to perform vehicle classification counts, it is necessary to find innovative ways to collect vehicle class data on roadways.Continue reading New Project: Refining Inductive Loop Signature Technology for Statewide Vehicle Classification Counts
