When drivers approach a roadway work zone at high speeds, they put the lives of work-zone flaggers at risk. To keep flaggers safe on the job, U of M researchers are looking for better ways to capture drivers’ attention—and compel them to slow down—as they approach flagger-controlled work zones.
Kathleen Harder, director of the Center for Design in Health, and John Hourdos, director of the Minnesota Traffic Observatory, identified and tested new work-zone warning elements to more effectively capture and sustain driver attention. The project was funded by the Minnesota Department of Transportation and the Minnesota Local Road Research Board.
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.
In the United States, speeding is by far the leading factor in fatal crashes—equivalent to the use of drugs, alcohol, medication, and distracted driving combined. But although automated speed enforcement (ASE) is a promising countermeasure shown to reduce speeding and crashes, the idea remains contentious.
“Despite the demonstrated safety benefits of ASE, we’ve seen its deployment continue to be a highly controversial issue,” says Frank Douma, director of the State and Local Policy Program at the Humphrey School of Public Affairs. “Several states have enacted restrictions or even banned the use of ASE systems, and ASE has been rejected in a number of public referendums.”
To chart a possible path to ASE deployment, U of M researchers have completed a new study focusing on ASE in Minnesota. The research team included Douma, graduate research assistant Colleen Peterson with the Humphrey School, and Nichole Morris, principal researcher with the HumanFIRST Lab. The project was funded by the Roadway Safety Institute.
In observance of National Bike Month and Bike to Work Week 2017, Brendan Murphy of the U of M’s Accessibility Observatory shares his work on bicyclist safety in Minneapolis in this guest post.
More people are biking or walking to work in North American cities each year, including here in the Twin Cities. With increased biking and walking, more opportunities for conflict with cars exist, and the safety of our more vulnerable road users becomes an increasingly important consideration.
The goal of this study, funded by the Roadway Safety Institute, was to attempt to predict crash rates between cars and bicycles at street intersections in Minneapolis—based on car and bike traffic levels—and then assess whether areas of the city exist that have much higher per-bicyclist crash rates.
Imagine that you’re driving to work as usual when your smartphone announces, “Caution, you are approaching an active work zone.” You slow down and soon spot orange barrels and highway workers on the road shoulder. Thanks to a new app being developed by University of Minnesota researchers, this scenario is on its way to becoming reality.
“Drivers often rely on signs along the roadway to be cautious and slow down as they approach a work zone. However, most work-zone crashes are caused by drivers not paying attention,” says Chen-Fu Liao, senior systems engineer at the U’s Minnesota Traffic Observatory. “That’s why we are working to design and test an in-vehicle work-zone alert system that announces additional messages through the driver’s smartphone or the vehicle’s infotainment system.”
As part of the project, sponsored by the Minnesota Department of Transportation, Liao and his team investigated the use of inexpensive Bluetooth low-energy (BLE) tags to provide in-vehicle warning messages. The BLE tags were programmed to trigger spoken messages in smartphones within range of the tags, which were placed on construction barrels or lampposts ahead of a work zone.
April is National Distracted Driving Awareness Month—a perfect time to remind all drivers to put safety first, put down their devices, and focus on driving.
According to the National Highway Traffic Safety Administration, distracted driving claimed nearly 3,500 lives and injured approximately 391,000 people across the country in 2015. Teens were the largest age group reported as distracted at the time of fatal crashes.
At the University of Minnesota, efforts to reduce distracted driving range from research projects to education initiatives.
It’s National Work-Zone Awareness Week (NWZAW), and this year’s campaign urges drivers to recognize that work-zone safety is in their hands. NWZAW is held each year in the spring to bring national attention to motorist and worker safety and mobility issues in work zones.
University of Minnesota researchers are always working on new solutions to help improve work-zone safety. Read the full post for examples of recent and ongoing projects.
