Abstract The objective of this paper is to establish a statistical relationship correlating crash severity with weather, traffic maneuve rs, and specific roadway geometrics at four-legged signalized intersections in rural areas. In this paper, the probability of the levels of injury severity is examined by applying ordered probit regression models for all crash types, single-vehicle crashes, two-vehicle cras hes, and three or more-vehicle crashes. The study results suggest that in terms of crash severity for all crash records, more vehicl e presence of protected left lane, wider median widths, and higher traffic flows, and more driveways are associated with less injury severity of intersections. By the number of vehicles involved in crashes, the variable shows variations in the models and magni tudes of the estimates.
