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

LaJeunesse, Seth

Evenson, Kelly R.
Fiedler, Lisa M.
Cooper, Jill F.

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...

How effective are community pedestrian safety training workshops? Short-term findings from a program in California

Barajas, Jesus M.

Lopez, Ana
Reynosa, Amanda

Introduction: Pedestrians and bicyclists make up a disproportionate share of road deaths and injuries, and low-income, majority person-of-color communities tend to face the greatest danger. Comprehensive pedestrian safety programs targeted toward such communities have the potential to build communities’ capacity to address safety issues, but there is a lack of systematic research and evaluation on how effective these programs are.

Methods: We use a mixed-methods approach of surveys, participant observation, and follow-up interviews to evaluate a...

Introducing an Intelligent Intersection

Yu, Mengqiao

This project seeks to remove one important cause of intersection accidents: drivers, pedestrians and cyclists make mistakes because they lack sufficient information about the movement of others as they proceed through an intersection. There is spatial and temporal uncertainty. This missing information can be supplied by an ‘intelligent intersection’. It describes the signal from all approaches; predicts when the signal phase will change; uses sensor data to determine which blind spots are occupied; and predicts red light violations before they occur. The intelligent intersection broadcasts...
