MnDOT and the Local Road Research Board research proposals have been selected for funding in FY2020 by the Minnesota Department of Transportation Research and Innovation Group (TRIG) and/or the Minnesota Local Road Research Board (LRRB). View the list of selected projects. (Posted 12/19/2018)
Research At-A-Glances serve as quick-reference guides to our MnDOT and Local Road Research Board research programs and list projects active in the last fiscal year. They include project highlights, an overview of the research process and information about our Transportation Research Synthesis program. (Posted 1/30/2018)
Typically used for parking lots and sidewalks, porous paving material allows stormwater to filter through the pavement and an aggregate base into the soil rather than run off the pavement and drain into storm sewers. Shoreview bucked convention by using pervious concrete in a traffic application — low-volume, low-speed roads in the Woodbridge neighborhood near Lake Owasso. (Posted 9/21/2018)
Dynamic warning signs provide real-time traffic information to motorists at non-signalized intersections. However, a number of sign-related complaints have been received from local road users. Researchers identified an alternative sign design for future field tests that may demonstrate comparable safety benefits to the original sign with fewer potential risks. (Posted 9/21/2018)
Researchers use detailed and specific data sets as tools to investigate freight truck mobility, reliability and extent of congestion delays on Twin Cities metropolitan area corridors. Precise locations and times of recurrent delays will help to mitigate future traffic bottlenecks. (Posted 9/21/2018)
Minnesota has many miles of low-volume roads, most marked with yellow centerline and white edge lines. Applying and maintaining these markings is a significant financial investment for local agencies, which typically work within very constrained budgets. Researchers developed a prioritization approach and a decision-making tool that incorporated both past research and the local state of the practice. (Posted 9/21/2018).
