Pedestrian and Bicycle Safety Research Brief

July 18, 2017

Data is the bread and butter of safety analysis. This research brief highlights three new peer-reviewed studies that focus on questions around pedestrian and bicycle safety data and the patterns they identify. Read the full Pedestrian and Bicycle Safety Research Brief to explore our findings

2025 Follow-up survey highlights the impact of the Community Pedestrian and Bicycle Safety Training

August 6, 2025
Preliminary Statewide Integrated Traffic Records System (SWITRS) data for 2024 indicates that traffic crashes caused 3,376 preventable deaths statewide, of which 950 were pedestrians and 148 bicyclists. Additionally, in 2024, there were 16,142 people seriously injured in traffic crashes in California, including 2,531 pedestrians and 1,255 bicyclists. These deaths are unacceptable and preventable. Ensuring that our communities are safe for walking, biking and rolling is critical...

Drivers, Pedestrians, and Cyclists in California Want Complete Streets: Comparison of Results from Roadway Design Surveys of Pedestrians, Drivers, Bicyclists, and Transit Users in Northern and Southern California

This paper compares findings from two recent surveys on roadway design preferences among pedestrians, drivers, bicyclists, and public transit users along major urban corridors in the metro areas of San Francisco and Los Angeles. Sponsored by the California Department of Transportation (DOT), the research explored design preferences that could increase perceived traffic safety, walkability, bikability, and economic vitality along urban arterials. Results from intercept surveys showed that roadway users desire similar design features along the test corridors, which carry 25,000-40,000...

Pedestrian and Bicycle Safety Research Brief

Barajas, Jesus M.
2016

As cities around the country adopt initiatives like Vision Zero to eliminate traffic deaths and serious injuries, they are faced with the question of how effective different types of interventions are. For example, do protected bike lanes or painted sharrows reduce the risk of severe injury to cyclists? A group of researchers from the New York University School of Medicine examined this question by studying where cyclists admitted to the hospital crashed and how severe their injuries were. This research brief explores their findings.

In January 2017, over 13,000 transportation professionals gathered in Washington, DC, at the Annual Meeting of the Transportation Research Board (TRB). In all, there were over 5,000 research presentations, 600 of which were about transportation safety. In this brief, we highlight some of the newest practice-ready pedestrian and bicycle safety research to come out of the conference.

Complete Streets and their effect on increasing safety for all road users

Yavari, Afsaneh
2018

Complete Streets is a transportation policy and design concept that promotes safe and convenient access to roadways for users of all transportation modes including walking, biking, driving motor vehicle, and riding public transportation. The Complete Streets concept is a shift from planning and designing streets with motor vehicles as the dominant mode. Complete Streets explicitly ac­knowledges the mobility and safety needs of all road users by all modes.

Why Don't Women Cycle? A Case Study of Women's Perceptions of Cycling in San Francisco

Funaki, Dorry
2019

Safety and women’s perceptions of safety is a prevalent factor affecting the gender gap of cycling within the US. In this study, the use of bike lanes in the South of Market Area of San Francisco found that only 29% of the cyclists were female despite accounting for 50% of the population in the area. This research brief summarizes key issues found in this study of women’s perceptions of safety when cycling.

Community Trainings at Work: An Evaluation of Community Pedestrian and Bicycle Safety Trainings

Beck, Kate M.
2019

The Community Pedestrian Bicycle Safety Training (CPBST) program trains and mobilizes communities to address pedestrian and bicycle safety and strengthens collaboration with local officials and agency staff. This research brief summarizes an evaluation of the CPBST program completed in 2018.

Engagement of Latine Communities in Transportation Safety

Introduction

Public participation in government is a foundation of democracy; however, it exists on a spectrum. In the field of transportation, decision-makers may seek information by simply making public announcements to invite input. Alternatively, governments devote resources to conduct thoughtful and extensive outreach to seek meaningful input. Recently, professionals and policymakers have considered an equity approach not only to reach and engage a diverse, representative group of community members, but to develop plans, projects, and policies that are...

Peer Influence and Perceptions of Safety

Aqshems Nichols

2022

At the heart of active transportation systems are the people. This brief discusses the importance of considering perceptions in traffic safety analyses and discusses the potential for investigating how a psychological phenomenon known as pluralistic ignorance could be shaping those perceptions. A couple of case studies from the psychology literature are discussed to facilitate this discussion. It is hoped that this brief can be employed to learn more about how to improve the safety of using active modes both in California and across the nation.
