This report documents the calibration of the Highway Safety Manual HSM safety performance function SPF for rural two-lane two-way roadway segments in Utah and the development of new models using negative binomial and hierarchical Bayesian modeling techniques.

Crash data from on selected study segments in Utah provided a 3-year observed crash frequency to obtain a calibration factor for the HSM SPF and develop new models. Negative binomial regression was used to develop four new models, and one additional model was developed using hierarchical or full Bayesian techniques.

The empirical Bayes EB method can be applied with each negative binomial model because the models include an overdispersion parameter used with the EB method.
