Evaluating Research on Data Linkage to Assess Underreporting of Pedestrian and Bicyclist Injury in Police Crash Data

Traffic safety decisions are based predominantly on information from police collision reports. However, a number of studies suggest that such reports tend to underrepresent bicycle and pedestrian collisions. Underreporting could lead to inaccurate evaluation of crash rates and may under- or overestimate the effects of road safety countermeasures. This review examined ten studies that used data linkage to explore potential underreporting of pedestrian and/or bicyclist injury in police collision reports. Due to variations in definitions of reporting level, periods of study, and study...

Emergency Medical Services (EMS) and the California EMS Information System (CEMSIS) Working Paper

This study examines data from the California EMS Information System (CEMSIS) to identify factors that influence prehospital time for EMS events related to motor vehicle collisions (MVCs). While only 19 percent of the United States population resides in rural areas, over half of all traffic fatalities involve rural motor vehicle collisions. Rural and urban MVCs result in similar injury severities, however relative inaccessibility of trauma centers and prehospital EMS time (activation, response, and transport time) likely contribute to the generally higher mortality rate in rural areas...

Prehospital Response Time and Traumatic Injury—A Review

A significant proportion of fatalities from motor vehicle collisions (MVC) could be prevented through better emergency medical service (EMS) care. Despite a lack of conclusive research, there is a consensus that prehospital time (the time between the MVC and the patient’s arrival at the hospital) must be reduced as much as possible. Many studies use response time (the time between EMS dispatch and arrival at the scene) as an indicator of overall prehospital time and a metric of EMS performance. However, there are other components of prehospital time that may be equally important, including...

Reflections on the 2019 Safe Systems Summit: Redefining Transportation Safety

June 7, 2019

According to the latest data from the National Highway Traffic Safety Administration (NHTSA), there were 37,133 traffic fatalities on U.S. roadways in 2017, a 1.8-percent decrease from the 37,806 people killed in 2016. While there has been a general downward trend downward in traffic fatalities overall, this is still an alarmingly high number of deaths – and there have been troubling increases for vulnerable road users like pedestrians. A...

The Goal of Road Safety in the Safe Systems Context

Safe Systems is an approach to road safety that envisions the elimination of fatal and serious injuries and seeks to provide both a theoretical framework and practical roadmap for accomplishing such an ambitious goal. The Safe Systems approach involves a paradigm shift from traditional approaches to road safety planning and responsibility. This fact sheet provides an overview of the Safe Systems Approach and how it relates to both current road safety practice and initiatives such as Vision Zero. Read the full...

New Publication: Diffusing innovative road safety practice

February 1, 2019

As another month begins, we are excited to announce another SafeTREC publication!

SafeTREC co-director Jill Cooper has co-authored a study published in the Journal of Traffic Injury Prevention, titled “Diffusing innovative road safety practice: A social network approach to identifying opinion leading U.S. cities” with University of North Carolina at Chapel Hill researchers Seth LaJeunesse, Stephen Heiny, Kelly Evenson, and Lisa Fiedler. The study, funded by the...

Diffusing innovative road safety practice: A social network approach to identifying opinion leading U.S. cities

Objective: This study sought to identify opinion-leading U.S. cities in the realm of safe transportation systems by surveying road safety professionals and asking them to identify places that served as models for road safety.

Methods: Using a purposive sampling methodology, we surveyed professionals employed in road safety–related professions (e.g., transportation engineering, planning, public health, law enforcement, and emergency response). Using 183 professionals’ complete responses, we carried out social network analysis to both describe the...
