Electric scooters let riders move quickly between the roadway and the sidewalk, but these sometimes-unpredictable travel patterns can pose risk for riders and the people around them. Making scooters smarter is the goal of a new U of M research project funded by the National Science Foundation (NSF). Under the $1.2 million Cyber-Physical Systems grant, a cross-disciplinary team will study smart tracking systems on scooters for ensuring safe and smooth interaction with other vehicles and pedestrians.

More than five years ago, U of M researchers studied a group of new teen drivers to gauge the effects of real-time, in-vehicle coaching with their innovative Teen Driver Support System (TDSS) smartphone application. Now, a follow-up study offers new understanding about the system’s long-term effectiveness in reducing risky driving behavior.

By connecting measures of happiness to transportation, researchers are developing new metrics that can help cities prioritize infrastructure investments. In a new study, a research team that included Humphrey School of Public Affairs professor Yingling Fan found that air quality appears to be linked with a variety of emotional well-being (EWB) outcomes.
A new research study has shown that few landowners know about MnDOT’s snow fence program, its benefits to community safety and mobility, and incentives to install snow fences. Following community meetings and surveys in four regions of Minnesota, researchers identified promising promotional methods for the snow fence program, the constraints landowners face in adopting snow fences, and incentives and assistance to improve snow fence adoption. Project results will guide MnDOT’s efforts to expand the use of snow fences around the state
A new study sponsored by the Minnesota Local Road Research Board has identified 1,000 feet as an optimal sight distance for allowing drivers to make better crossing decisions at rural intersections. Researchers used a state-of the-art driving simulator to examine drivers’ ability to judge traffic speed and gaps between cars at unsignalized intersections with varying sight distances.
Using an existing county road
project as context, researchers examined the digital technologies and processes
associated with civil integrated management (CIM). A comparison of CIM with the
traditional methods used in the proposed county project demonstrated the advantages
of CIM.
A new MnDOT-funded research study has found that most agencies in states with weather similar to Minnesota’s use debonded strands in prestressed concrete bridge beams. MnDOT may begin piloting debonding as an alternative to draping, which manufacturers claim is time-consuming, challenging to worker safety and expensive.
Turtles and other wildlife are at risk along Minnesota roadways.
MnDOT is collaborating with the Minnesota Zoo on a new research
project installing small animal exclusion fencing. The fencing is
intended to redirect turtles (and other small animals) to culverts and bridges
where they can cross the road safely.
Researchers ran a sophisticated low-temperature asphalt cracking performance test at multiple labs to study the test, its variability and repeatability, and its additional promise in studying reflective cracking susceptibility of overlays. Results put MnDOT closer to implementing test specifications for low-temperature cracking test for pavement mixes.
