Abstract EN
This study examines the effects of wet pavement surface conditions on the likelihood of occurrences of nonsevere crashes in two- and four-lane urban and rural highways in Alabama.
Initially, sixteen major highways traversing across the geographic locations of the state were identified.
Among these highways, the homogenous routes with equal mean values, variances, and similar distributions of the crash data were identified and combined to form crash datasets occurring on dry and wet pavements separately.
The analysis began with thirteen explanatory variables covering engineering, environmental, and traffic conditions.
The principal terms were statistically identified and used in a mathematical crash frequency models developed using Poisson and negative binomial regression models.
The results show that the key factors influencing nonsevere crashes on wet pavement surfaces are mainly segment length, traffic volume, and posted speed limits.
