Analyzing the heterogeneous effects of curve alignment and grade on truck crash injury severity on mountainous freeways: A correlated random-parameter binary logit analysis

OBJECTIVES: To examine how roadway geometry and related crash, vehicle, and environmental factors are associated with truck crash injury severity on mountainous freeways while accounting for unobserved heterogeneity and covariance among random coefficients. METHODS: This study an...
