This paper describes a dynamic segmentation application that allows roadways to be quickly segmented for highway safety analysis. After roadways are segmented (either variable-length or fixed-length), the system can automatically calculate the crash statistics associated with each segment, which can then be used to identify high-crash locations, to model the relationships between crash experience and geometric features, etc. The system can output segmented records in different formats, including in tables, 2-D and 3-D charts, and GIS shape files.
