Grouped random parameters Poisson-Lindley model with spatial effects addressing crashes at intersections: Insights from visual environment features and spatiotemporal instability

Contribution

Integrates visual environment features and spatial effects to study intersection crash frequency and variation across locations and periods.

This paper is part of the spatiotemporal heterogeneity and Bayesian/statistical safety modeling theme. It studies how intersection crash patterns vary with visual environment features and spatial structure.
