Hit-and-run crashes are on the rise

By Michael Brenneis Hit-and–run fatal crashes are increasing in the United States. Why? The short answer is that we don’t entirely know. Studies are limited, and data regarding the characteristics of drivers and victims is not extensive. Many hit-and-run drivers get away. Witnesses may not be

Research finds R1-6 gateway treatment can rival RFFB and PHB lights at pedestrian crossings

By Robbie Webber Research in Michigan has shown that in-street, yield-to-pedestrian signs can affect both yielding behavior and driver speeds approaching crosswalks to the same degree as installation of a Rectangular Rapid Flashing Beacon (RFFB) or Pedestrian Hybrid Beacon (PHB.) This is good

Study of bicycling and driving behavior reveals areas for improvement

By Robbie Webber A new report based on research by the USF Center for Urban Transportation Research and sponsored by Florida DOT details new methods for studying bicycling safety by mounting cameras and sensors on bikes ridden in naturalistic settings. The research gives us insight into the

Where people walk: Two new studies improve “walkability” measurement

By Chris McCahill In planning and designing for pedestrians, sidewalks are often a good start but rarely make a place walkable on their own. Measuring pedestrian accessibility (the topic of a recent SSTI webinar) depends on two important pieces of information: 1) where destinations are located,

What is ride-hailing doing to our transportation system?

By Robbie Webber A new study from the Institute of Transportation Studies at University of California–Davis delves into the effects of ride-hailing (Uber and Lyft) use on other parts of our transportation system. What they find confirms some assumptions and disproves others. Interrelationships

CAFE standards may be easier to meet than previously thought

By Sam Sklar Consumers might favor vehicles that accelerate a little slower, if the vehicles are also much more fuel conscious and greenhouse gas friendly. That is the conclusion of a study published in Environmental Science & Technology by researchers at Carnegie Mellon, UC-Berkeley, and

Alcohol and gasoline prices: Their impact on traffic fatalities and the economy

By Logan Dredske Alcohol and gasoline prices are having unexpected impacts on traffic fatalities, as well as causing damage to economies. A study by Onyumbe Enumbe B. Lukongo, an economics professor at Southern University and A&M College in Louisiana, explored the relationship between per

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
