Calibration of the Highway Safety Manual in Missouri

This report describes the challenges, practical solutions, and results from a statewide HSM calibration in Missouri, including lessons learned from other states such as Kansas, Illinois, and New Hampshire. The models calibrated included five segment and eight intersection site types, as well as three freeway segment types that will be part of the next edition of the HSM. The calibration results indicated that the HSM predicted Missouri crashes reasonably well, with the exception of a few site types for which it may be desirable for Missouri to develop its own SPFs.
