The risk of dying or being seriously injured in a car crash varies with age; teens and older drivers are the two highest-risk populations on the road. To help address teen driving dangers, HumanFIRST Laboratory researchers at the U of M developed smartphone technology that improves safety by monitoring risky behaviors such as speeding, stop sign violations, aggressive driving maneuvers, and seat belt use and notifying a parent about them. In a new study, the researchers explored adapting this system to meet the needs and limitations of aging drivers.
Fleets of shared autonomous vehicles will be on our roads within a decade as part of mobility services offered by both car and technology companies, says Professor Tom Fisher, director of the Minnesota Design Center at the U of M. This transportation revolution will have a profound effect on our infrastructure and land use as well as on employment, the environment, and the economy. Fisher provides insights for community leaders and planners to prepare for these changes.
University of Minnesota Duluth researchers are identifying new ways for transportation agencies to meet regulatory requirements for stormwater runoff. The team evaluated the use of peat and muck excavated from construction activities, taconite tailings from mining operations, and other stormwater filter media for use in bioswales and bioslopes along northeastern Minnesota highways. Their results could reduce costs for the Minnesota Department of Transportation and Minnesota local agencies.
In a study with implications for both trucking companies and policymakers, researchers at the University of Minnesota Morris have found that non-adherence with employer-mandated sleep apnea treatment increases the risk of serious truck crashes. The study examined the first-ever employer-mandated program for diagnosing and treating this disease among drivers and found a large and statistically significant association between non-adherence with treatment and preventable tractor-trailer crashes.
