Connected Automated Vehicles (CAV) are part of tomorrow’s transportation future happening today. The evolution of vehicle technology is shifting how drivers interact with the infrastructure around them. Local agencies are beginning to respond and anticipate these changes, while CAV manufacturers request to test their vehicles on local roadways further pushing the urgency on local agencies.Continue reading New Project: Autonomous Vehicles – What Should Local Agencies Expect?
A new guidebook published by the Minnesota Local Road Research Board offers a uniform approach and practical methods for selecting locations and the right treatment for uncontrolled pedestrian crosswalks in Minnesota.
The Minnesota Local Road Research Board has published a new guidebook to help local agencies get started on developing a consolidated asset management system. The guide addresses the particular needs of smaller groups to effectively and optimally manage their roadways, buildings, vehicles, equipment and other assets.Continue reading Asset Management Guide Addresses needs of Local Agencies
In a recently completed project, funded by the Local Road Research Board, researchers developed a reference tool and compiled a literature review that local agencies could use to anticipate the infrastructure needs of connected and automated vehicles. Agencies can use these resources to plan for infrastructure upgrades and maintenance activities.Continue reading Resources Help Local Agencies Plan for CAV Roadway Needs
Many local agencies in Minnesota lack funding to construct and maintain all the bridges in their roadway network. One way to lower costs is to reduce the number of bridges.
In Minnesota, some township bridges are on roads with low usage that have alternative accesses for nearby residents, but local officials are reluctant to remove the bridges.
To identify possible changes to how redundant and low-use bridges are identified and removed in Minnesota, the Local Road Research Board conducted a transportation research synthesis, “Local Bridge Removal Policies and Programs,” that explores how other states make bridge removal decisions.
Fifteen state DOTs responded to a survey about their processes, with varying levels of state oversight identified for bridge removal decisions. Researchers also examined funding and incentives offered by some DOTs to local agencies for bridge removal, as well as criteria for considering bridge removal.
A literature search of bridge design manuals, inspection manuals and bridge programs was also conducted to identify related policies and programs.

Across Minnesota, local agencies need better information about where and how many people are biking and walking to make decisions about infrastructure investments, understand safety risks, and even plan active living initiatives.
To help provide agencies with bicycle and pedestrian traffic data, U of M researchers have been working with MnDOT on the Minnesota Bicycle and Pedestrian Counting Initiative since 2010. The initiative is a collaborative, statewide effort to support bike and pedestrian traffic monitoring by local, regional, and state organizations.
Recently, the project team completed an implementation study—the second of three MnDOT-funded projects related to the initiative—specifically designed to engage local agencies. The goal was to demonstrate the feasibility of using both permanent and portable sensors to collect bicycle and pedestrian traffic data in several Minnesota cities, suburbs, and small towns.
“If we want to institutionalize counting and monitoring across the state, local agencies need to know it’s not something that’s only important for large cities like Minneapolis,” says principal investigator Greg Lindsey, professor at the Humphrey School of Public Affairs and current MnDOT scholar-in-residence. “We have to be on the ground in these places, illustrating that it’s relevant to the decisions they’re making.”
To that end, the team installed commercially available sensors—including inductive loops, passive infrared, pneumatic tubes, and radio beams—to collect traffic counts in several Minnesota cities. Overall findings indicate that all of the sensors produced reasonably accurate measurements—and that participating agencies found value in the collected data.
Findings and case studies from the study have already been incorporated into the draft Bicycle and Pedestrian Data Collection Manual, a new MnDOT guidance document being used in statewide training workshops. Also as a result of the study, MnDOT plans to include commitments to bike and pedestrian traffic monitoring in its forthcoming statewide bicycle and pedestrian plans. In addition, MnDOT is investing in a network of permanent traffic monitoring sites around the state as well as in portable equipment that will be available to local agencies.
