Uncovering manufacturers’ perspectives on the transportation system

It’s no secret that manufacturing plays a key role in driving economic growth, or that transportation is essential for the success of any manufacturing operation.

While the relationships among manufacturing, transportation, and economic growth have been studied on a large scale, there is often little dialogue between transportation organizations and the manufacturers themselves. A recently completed pilot study conducted jointly by the Minnesota Department of Transportation (MnDOT), the University of Minnesota Humphrey School of Public Affairs, and University of Minnesota Extension aims to address this communication gap.

The pilot project focused on 12 counties in southwest Minnesota, where more than 172 regional businesses were contacted for participation and 75 in-person interviews were completed with manufacturers, shippers, and carriers. During the interviews, participants were encouraged to focus their comments on high-value, low-cost improvements that MnDOT can address in the short term without over-promising projects that currently cannot be funded.

Participants identified the need for smooth pavements and wide shoulders, the value of advance warning lights at intersections with traffic signals, the importance of highway safety, and the challenges of maneuvering oversized vehicles through roundabouts, among others.

The research team is compiling the pilot study’s findings into a final report. In the meantime, MnDOT is working to address a number of the challenges and suggestions uncovered through the pilot program.

MnDOT, LRRB announce new research projects

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.”

Previewing MnDOT’s next round of research projects

MnDOT Research Services recently released its 2013 request for proposals. If you have any kind of direct interest in transportation research in Minnesota, chances are you might have known that already. But those with more of a general curiosity might be interested to see the list of research need statements from the RFP, as they provide a nice preview of the next round of potential MnDOT research projects.

As you can see, some are of a highly technical nature. (It’s safe to say that a study on “PCC Pavement Thickness Variation Versus Observed Pavement Distress” would be of interest mainly to engineers.) Others, however, like “The Economic Impact of Bicycling in Minnesota,” might have a broader appeal. In any case, it’s a fascinating glimpse at the myriad of issues that MnDOT is attempting to address through research and innovation.

Here’s the list of research need statements from the 2013 RFP, broken down by category:
