System uses smartphone app to warn drivers of high-risk curves

MnDOT2018-12Lane-departure crashes on curves make up a significant portion of fatal crashes on rural Minnesota roads. To improve safety, solutions are needed to help drivers identify upcoming curves and inform them of a safe speed for navigating the curve.

“Traditionally there are two ways to do this: with either static signage or with dynamic warning signs,” says Brian Davis, a research fellow in the Department of Mechanical Engineering. “However, while signing curves can help, static signage is often disregarded by drivers, and it is not required for roads with low average daily traffic. Dynamic speed signs are very costly, which can be difficult to justify, especially for rural roads with low traffic volumes.”

In a recent project led by Davis, researchers developed a method of achieving dynamic curve warnings while avoiding costly infrastructure-based solutions. To do so, they used in-vehicle technology to display dynamic curve-speed warnings to the driver based on the driver’s real-time behavior and position relative to the curve.

RCP selects Scott and Ramsey Counties as next community partners

The University of Minnesota’s Resilient Communities Project (RCP) recently announced that Ramsey County and Scott County will be its community partners for the 2018–2019 academic year. It’s the first time in the six-year history of the program that it will assist two partners in the same year.

RCP, housed within the U of M’s Center for Urban and Regional Affairs, seeks to connect students’ innovation, ingenuity, and fresh perspectives with local government agencies to learn about their needs, conduct research, and develop solutions. In the coming months, staff will define the scope and purpose of individual projects before matching them with courses offered at the University in fall 2018 and spring 2019.

Ramsey County’s proposal identified up to 18 potential projects, including removing transportation barriers to employment and exploring innovative stormwater management practices. Scott County’s proposal identified 14 potential projects, including planning for autonomous vehicles and promoting active living.

Women in aviation take flight

mcoa-minnesotaairportsconference2018-0272-300ppi-6016x4016At this year’s Minnesota Airports Conference, held April 18-20 in Duluth, three successful women shared their experiences breaking down barriers in the aviation industry. Despite different backgrounds and career paths, these women shared the belief that they could do whatever men could do—and had the drive to push through when they were told otherwise.

In a panel discussion at the conference, the women talked about how they got started, where they found support, and what unique challenges they faced in a male-dominated field.

Social media can be effective part of public engagement plans

shutterstock_662208199Social media can be effective as a strategic and select part of public engagement plans, according to findings of a U of M study. Co-principal investigators were Professor Ingrid Schneider of the Department of Forest Resources and Associate Professor Kathryn Quick of the Humphrey School of Public Affairs. “Public engagement for transportation planning and programs is not only required, it’s a crucial component in policy and project success,” Schneider says. “Since 2000, advances in technology and communications provide opportunities to engage with more people in new ways.”

The multipronged, multiyear project investigated current knowledge about public engagement through social media nationwide and in Minnesota. It also developed guidance about how social media may be used to reach and engage diverse populations in the state about transportation planning and projects.

Otter Plow Cushion absorbs shock of rough roads

Snowplow truck with Otter Plow Cushion Winter roads, especially late in the season, can be especially rough, causing more stress on snowplow lift chains and plow lift parts as the heavy plow assembly bounces more. Broken plow lift chains are a common result and can take maintenance vehicles and personnel out of service for hours.

Industrious maintenance personnel with the Otter Tail County Highway Department created the Otter Plow Cushion with spare parts during downtime on a cold winter day. The device absorbs the shock of rough roads on the plow assembly and lift chains, improving ride quality and reducing the failure of the plow lift chains and parts.

The Otter Tail County Highway Department received a grant through the Local Operational Research Assistance (OPERA) Program to produce more Otter Plow Cushions.

U of M researchers to begin new roadway safety projects

U of M researchers have received funding from the Roadway Safety Institute for nine new projects focused on advancing roadway safety. Topics range from developing a course on automated vehicle technologies to improving EMS response on American Indian reservations.

The newly funded projects are specifically focused on moving current Institute research toward implementation, positioning its researchers for future opportunities, or developing educational initiatives. Projects were required to fall under the Institute’s research focus areas of rail-crossing safety, safety on tribal lands, bicycle and pedestrian safety, connected vehicles, or safety policy.

U of M hosts autonomous bus demo on Washington Avenue Bridge

autonomousbusdemo2018-0764-300ppi-3008x2008On Monday, April 30, an innovative demonstration of a self-driving EZ10 All Electric Autonomous Bus offered free rides to students, staff, faculty, and the public across the Washington Avenue Bridge.

More than 450 people took a three-minute ride across the bridge during the demo, which was organized by the U of M’s Parking & Transportation Services, CTS, the Humphrey School’s State and Local Policy Program, the University Office of Sustainability, and First Transit, Inc.
