2012

This methodological report describes survey research and data collection methods employed for the first observational survey of cell phone use and texting by California drivers. This study was conducted by Ewald and Wasserman Research Consultants on behalf of the California Office of Traffic Safety and the Safe Transportation Research and Education Center at the University of California, Berkeley. The goal of the survey was to obtain a statewide, statistically representative observational sample. Vehicle drivers were observed at controlled intersections, such as traffic lights and stop...

Reasons Given by Older People for Limitation or Avoidance of Driving

Ragland, David R.

MacLeod, Kara E.
2002

Purpose: To understand the driving behavior of older adults, this study examines self-reported reasons for driving limitation or avoidance.Design and Methods: Baseline interviews were conducted (n = 2,046) as part of a community-based study of aging and physical performance in persons aged 55 years or older in Sonoma, California. Twenty-one medical and nonmedical reasons for limiting or avoiding driving were examined by age and gender. Results: Most older people continue...

Classification of Bicycle Traffic Patterns in Five North American Cities

This paper analyses bicycle ridership patterns using a unique database of automated bicycle counts from approximately 40 locations in five North American cities and along the Route Verte in Quebec. The cities involved in this study are Montreal, Ottawa, Portland, San Francisco, and Vancouver. Count data show that the bicycle volume patterns at each location can be classified as utilitarian, mixed utilitarian, recreational and mixed recreational. Study locations classified into each of these categories are found to have consistent hourly and weekly traffic patterns, despite important...

A Multidimensional Clustering Algorithm for Studying Fatal Road Crashes

Fishbain, Barak

2014

Road fatalities are rare outcomes of events that occur in a small time-space region. Although the exact chain of events for each fatality is unique, there are inherent similarities between road fatalities. The science of road safety is dedicated to identifying such similarities, mainly using statistical analysis tools. Researchers typically analyze patterns that emerge over space, such as hot-spot studies, or patterns that emerge over time, such as before-after studies. Traffic research enumerates 84 parameters that characterize a road fatality. A vast number of papers have tried to...

Impact of the Community Pedestrian and Bicycle Safety Training: Program Insights from the 2023 Follow-Up Survey

The Community Pedestrian Bicycle Safety Training (CPBST) program is a collaborative project between UC Berkeley Safe Transportation Research and Education Center (SafeTREC) and California Walks (Cal Walks) that seeks to assist communities with three goals:

Identifying and better understanding their local transportation safety needs; Developing and strengthening local partnerships between various stakeholders in their community; and Generating a community-specific action plan for improving the safety of active transportation in their area.

These objectives are pursued through...

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

Doggett, Sarah
Ragland, David R.
Felschundneff, Grace
2018

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...

The CPBST at work in Florence-Firestone

June 25, 2019
Submitted by Kate Beck

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...
