Impact of the Community Pedestrian & Bicycle Safety Training Program: Insights from the 2022 Follow-Up Survey

July 29, 2022
Submitted by Lisa Peterson

According to the latest traffic safety data from the National Highway Safety Administration (NHTSA), there were 42,915 traffic fatalities in 2021, a 10.5% increase from 2020. This alarming trend was also seen for those walking and biking in our communities, with 7,342 pedestrian fatalities (a 13% increase from 2020) and 985 bicyclist/pedalcyclist fatalities (a 5% increase from 2020) in 2021. These deaths are unacceptable and preventable. Ensuring that our communities are safe for...

Everyone is a pedestrian, whether or not walking is one’s primary mode of travel. As a commute mode, walking is gaining in numbers. In 2020, pedestrian deaths accounted for 16.8 percent of all crash fatalities and nearly one-quarter (24.3 percent) of pedestrian fatalities involved a hit-and-run crash. From 2011 to 2020, pedestrian fatalities increased 46.2 percent while other traffic deaths only increased by 14.4 percent. From 2019 to 2020, pedestrian fatalities increased 3.9 percent, despite a 13.2 percent reduction in driving. Compared with all other racial categories, American Indian/...

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...

Learning the representation of surrogate safety measures to identify traffic conflict

Traffic conflict can be identified by the presence of evasive actions or the amount of temporal (spatial) proximity measures like time-to-collision (TTC). However, it is not enough to use only one kind of measures in some scenarios and it is hard to set a threshold for those measures. This paper proposed a method to identify traffic conflict by learning the representation of TTC and driver maneuver profiles with deep unsupervised learning and clustering the representations into traffic conflict and non-conflict clusters. We first trained a transformer encoder to encode sequences of...
