The accumulation of chloride in our waters has become a widespread concern. In a recent U of M study, researchers measured the transport and accumulation of chloride from road deicers in a metro-area watershed. The findings revealed a greater infiltration of chlorides into soil and subsurface waters than was previously assumed. The research will help investigators and policymakers explore ways to capture chlorides and mitigate their damaging environmental effects.
A new study from U of M researchers found that long-term transportation investments contribute significantly to employment in Minnesota counties, particularly rural ones. The study compiled a dataset about county business patterns in Minnesota during 1995–2010. According to the findings, the overall relationship (across all counties) is that the employment rate increases with trunk highway and local road spending. However, different areas are affected differently by investments.
For parents in low-income countries, getting their infants vaccinated on time can be difficult-to-impossible due to many issues—including a lack of transportation to clinics. To increase vaccination timeliness for infants, a U of M team is testing a new strategy in Uganda that may offer residents living in high-density urban areas cheap, reliable transportation to clinics through transportation network companies such as Uber and Safeboda.
A series of research projects under way since the early 2000s have culminated in a pavement design package that allows for the improved use of geogrid. This work—which will ultimately enable cities, counties, and the state to build more financially effective roadways—was honored with this year’s CTS Research Partnership Award.
