Crash Prediction Modeling For Curved Segments Of Rural Two-Lane Two-Way Highways In Utah, Casey Scott Knecht
Crash Prediction Modeling For Curved Segments Of Rural Two-Lane Two-Way Highways In Utah, Casey Scott Knecht
Theses and Dissertations
This thesis contains the results of the development of crash prediction models for curved segments of rural two-lane two-way highways in the state of Utah. The modeling effort included the calibration of the predictive model found in the Highway Safety Manual (HSM) as well as the development of Utah-specific models developed using negative binomial regression. The data for these models came from randomly sampled curved segments in Utah, with crash data coming from years 2008-2012. The total number of randomly sampled curved segments was 1,495. The HSM predictive model for rural two-lane two-way highways consists of a safety performance function …
