How Do Mode-Specific Network Metrics Impact Safety Outcomes?

Public transit and active transportation networks have been shown to enhance multimodal traffic safety, yet their impacts in rural and peri-urban areas remain underexplored. This research evaluates the role of mode-specific network metrics—quantifying size, structure, and connectivity—on crash outcomes across New England using crash data and socioeconomic variables. Predictive models incorporating regression and machine learning methods will identify which network features influence safety, providing actionable insights for urban planners and policymakers. Outputs include an open-access dataset of network metrics, a dashboard for visualizing results, and a decision-support tool for improving roadway safety and equity in diverse community settings.
