Minnesota’s next round of transportation research projects will explore using traffic signal data to predict crashes, evaluate various impacts of bicycling on the state and address a range of other transportation issues.
The state’s two transportation research governing boards have authorized funding for a total of 24 new research projects. MnDOT’s Transportation Research Innovation Group (TRIG) and the Local Road Research Board announced their Fiscal Year 2015 funding awards this week after hearing proposals from researchers in several states. MnDOT Research Management Engineer Hafiz Munir said the projects, which are listed below, reflect the needs of state and local practitioners.
“Many of the projects fall under the ‘traffic and safety’ or ‘materials and construction’ categories, which I think reflects MnDOT and local agency priorities,” Munir said. “Ultimately, all of these research projects address business needs of the people who build and maintain our roads.”
Links are provided to brief descriptions of each project (as provided by the researchers who submitted the proposals).
