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.

In-vehicle warnings show promise for improving work-zone safety

work-zone road signWork zones can be dangerous for both drivers and the work crew—but U of M researchers are working on innovative ways to lessen these risks and lower the rate of work-zone crashes. In a new study funded by MnDOT, researchers investigated the potential advantages and possible disadvantages of vehicle-to-infrastructure in-vehicle messages to communicate to drivers.

“When we started this project, we saw a potential for drivers to become more aware and responsive to hazards within the work-zone by presenting the information directly to them through in-vehicle messaging technologies,” says Nichole Morris, director of the U’s HumanFIRST Laboratory, who led the project. “We also wanted to assess the extent to which this type of messaging could lead to driver distraction, as numerous studies have demonstrated the hazards of distracted driving, particularly from interacting with on-board technologies.”

The researchers began by identifying ideal design guidelines for any in-vehicle messaging system. Then, the team conducted a survey to uncover driver attitudes in Minnesota toward work-zone safety, smartphone use, and the potential for receiving messages through in-vehicle technologies such as smartphones.

New warning systems aim to reduce rear-end crashes on Minnesota freeways

To reduce congestion and improve safety, the Minnesota Department of Transportation (MnDOT) has deployed active traffic management (ATM) technology on two freeways in the Twin Cities. The ATM system incorporates intelligent lane control signals placed over selected lanes at half-mile increments to warn motorists of incidents or hazards ahead.

Using this existing ATM infrastructure, U of M researchers have developed and field-tested two prototypes for queue warning systems in a new MnDOT-funded project. The warning systems specifically focus on preventing rear-end collisions—the most frequent type of crash on freeways.

Policies needed to ensure the promise of self-driving vehicles for those unable to drive

Dashboard of a self-driving vehicleOne of the predicted benefits of self-driving vehicles (SDVs) is improved mobility and access for those unable to drive. The extent to which this happens, however, will depend not just on marketplace competition, but also on public policy decisions that ensure an equitable transportation system.

This is the conclusion of a new analysis by Frank Douma, director of the State and Local Policy Program (SLPP) at the Humphrey School of Public Affairs; Adeel Lari, director of innovative financing at SLPP; and Kory Andersen, graduate student in urban and regional planning. The research was conducted under the Transportation Policy and Economic Competitiveness Program, which is led by SLPP.

New work-zone warning app featured on KARE 11

KARE 11 reporters interviewing researcher Chen-Fu Liao next to a highway work zone.A new app that sends warning messages to drivers as they approach work zones was featured on KARE 11 News on Thursday. The app was developed by U of M researchers in a project sponsored by MnDOT.

The story aired as part of KARE 11’s #eyesUP campaign to end distracted driving.

The app works by pairing with Bluetooth low-energy tags placed in work zones, triggering audio warnings in smartphones that are within their range. This allows drivers to get a warning message without having to look down at their phones—or at warning devices such as changeable message signs outside their vehicles.

U of M researchers join new Freight Mobility Research Institute

Trucks in highway trafficUniversity of Minnesota researchers at the Minnesota Traffic Observatory will work to improve the mobility of people and goods across the nation as part of the new Freight Mobility Research Institute, a Tier 1 University Transportation Center funded in 2016.

Led by Florida Atlantic University (FAU), the Institute will receive $1.4 million per year from the United States Department of Transportation for five years. A combined match from state and private-sector sources will bring the award to more than $10 million in total. In addition to FAU and the U of M, Institute members include the University of Florida, Portland State University, Hampton University, the University of Memphis, and Texas A&M University (College Station).
