Investigating Spatial Autocorrelation and Spillover Effects in Freeway Crash-Frequency Data

This study attempts to investigate spatial autocorrelation and spillover effects in micro traffic safety analysis. To achieve the objective, a Poisson-based count regression with consideration of these spatial effects is proposed for modeling crash frequency on freeway segments. In the proposed hybr...
