Sharing the road: How separated bikeways are setting the standard for safety

By Mary Ebeling As more cities and states strive to achieve goals for sustainability, pollution reduction, safety, and livability supporting active transportation has emerged as a key activity. In order to encourage bicycling, cities have been constructing new infrastructure that physically

New study reaffirms the child safety benefits of red light cameras

By Bill Holloway A study presented at the American Academy of Pediatrics national conference last month linked higher child death rates from motor vehicle crashes to several primary factors, including low rates of child seat belt/car seat use and a lack of red light cameras. While the full text

More evidence that wider roads encourage speeding

By Chris McCahill Wider lanes and shoulders encourage faster driving, according to a new study published in the Journal of Transportation Engineering. Researchers from Texas A&M studied uncongested freeways in Dallas, Houston, and San Antonio. Based on more than 650,000 observations, they

Are higher highway speed limits worth it?

By Bill Holloway A recent study indicates that raising speed limits on non-limited access highways from 55 to 65 miles per hour is likely to have a negative benefit-cost ratio when crash injury and fatality costs are fully accounted for. The analysis, which focused on non-limited access highways

Motor vehicle dependence is making us sick: How transportation and urban planners are part of the solution

By Mary Ebeling A recent study published in the medical journal The Lancet focuses on prevention strategies for the global epidemic of non-communicable diseases (NCDs) stemming from an unsustainable reliance on a transportation system reliant on fossil fuels. Such diseases include such as traffic
