UConn research center sets new standard with crash data and analysis tool

By Mary Ebeling Access to current and comprehensive crash data provides essential information for anyone seeking to improve the safety of road users. At the state and local level this type of data tool is not widely available to transportation safety engineers, law enforcement, local and regional

We all break traffic laws. Why are bicyclists different?

By Robbie Webber Bicyclists break traffic laws, but they do so at a lower rate than either drivers or pedestrians. It would be safe to say that almost 100 percent of roadway users break traffic laws. Yet the general public’s perception of lawbreaking behavior by drivers and bicyclists is vastly

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

Study: One-way car-sharing reduces VMT, GHG emissions, and vehicle ownership

By Robbie Webber A recent study done by researchers at University of California-Berkeley has answered several questions many have had since car-sharing began: Does car sharing increase or decrease driving? What is the effect on overall VMT, vehicle ownership, and GHG emissions among car-sharing

Report summarizes Wisconsin bicycle and pedestrian crash circumstances

By Robbie Webber A report released by University of Wisconsin-Milwaukee researcher Robert Schneider looks at crashes involving pedestrians and bicyclists throughout Wisconsin from 2011-2013 to determine the conditions behind the most serious crashes, those resulting in fatalities and serious

Canadian study links moving to walkable neighborhood with lower BMI in men

By Robbie Webber Research in the last ten years has linked walkability, improved pedestrian environments, mixed-use development, and even older housing stock—a proxy for neighborhoods built for walking as opposed to driving—with improved public health measures related to weight. A new

TDM study suggests we are overestimating vehicle trip generation rates

By Robbie Webber In a recent study done in Melbourne, Australia, researchers compared transportation demand management plans (called “travel plans” in Australia) at four new residential developments with control sites with similar characteristics. The study targeted new developments because

Parking drastically oversupplied across the country

By Chris McCahill On average, the amount of parking provided at mixed-use centers is 65 percent higher than necessary, according to a study just published in the Transportation Research Record. That finding challenges the perceived need for additional parking in many of those places. Meanwhile,

Does urban sprawl inhibit upward mobility?

By Robbie Webber A study by Reid Ewing, Shima Hamidi, et al. published in the journal Landscape and Urban Planning lends more support to the idea that sprawl can be a deterrent to upward mobility, making it difficult for low-income residents to improve their economic circumstances. Compact metro

New research on the benefits of ignition interlock devices

By Mary Ebeling New research from the University of Pennsylvania finds that states that have passed laws requiring ignition-interlock devices (IIDs) for all drivers convicted of drunk driving have seen a collective 15 percent drop in deaths from drunk-driving crashes compared with rates in states
