Understanding Pedestrian and Bicyclist Safety Trends in the Post-Pandemic Era

Project Description

The project aims to analyze trends in pedestrian and bicyclist crashes and deaths in the post-pandemic era and investigate the underlying factors that contribute to these trends. The study will examine the changes in crash rates during different phases of the pandemic, considering variations in vehicle-miles traveled and commuting patterns. Factors such as infrastructure, road usage patterns, and transportation mode preferences will be studied to understand their influence on pedestrian and bicyclist safety. Additionally, the project will integrate census tract-level transportation disadvantage indicators with crash data to explore the relationship between disadvantaged communities and crash trends, addressing equity concerns. The insights gained from this research will inform evidence-based interventions and strategies to enhance pedestrian and bicyclist safety. By identifying the key factors contributing to the observed trends, policymakers and transportation agencies can develop targeted measures to mitigate risks and improve safety for pedestrians and bicyclists in the post-pandemic era.
