To the extent possible, the Crash Prediction Module (CPM) includes a faithful implementation of Part C (Predictive Method) of the American Association of State Highway Transportation Officials' 1st Edition Highway Safety Manual (HSM) for evaluating rural two-lane highways, rural multilane highways, and urban/suburban arterials, as well as HSM 2014 Supplement materials on freeway segments and freeway ramps/interchanges, and prediction methods for roundabouts and six-or-more lane and one-way urban/suburban arterials (developed under NCHRP Project 17-70 and NCHRP Project 17-58, respectively, and intended for inclusion in the future 2nd Edition HSM (HSM2)). The IHSDM-which supports the Federal Highway Administration's Data-Driven Safety Analysis initiative-includes five evaluation modules (i.e., Crash Prediction, Design Consistency, Policy Review, Traffic Analysis, and Driver/Vehicle), as well as an Economic Analyses Tool.
