As a repository, ROSA P retains documents in their original published format to ensure public access to scientific information.
The primary objective of this study is to develop a set of mathematical models to estimate base crash rates for intersections in Ohio. The models will estimate the incremental changes in the dependent variables (crash rate for different types of crashes) resulting from changes in the independent variables (including geometric features, operational controls, and environmental conditions). Crash data and inventory data available with ODOT will be used to develop and validate the models. This methodology used in this study is similar to those successfully used by the previous research studies, “Rational Schedule of Base Accident Rates for Rural Highways in Ohio- Phase I and II.”
A safety analysis of a specific location includes a "base crash rate" analysis for identifying crash patterns at the study location. If the calculated...
