Abstract:

The overall objective of this effort was to estimate the calibration factors for all the prediction models in Part C of the 1st edition of the Highway Safety Manual (HSM) that are of interest to North Carolina Department of Transportation (NCDOT) as well as calibration factors for freeway models that are slated to be part of the next HSM based on the latest four years (2016 – 2019) of roadway, traffic, and crash data from North Carolina. For some of the models, separate calibration factors were developed for the three different regions in North Carolina (Coast, Mountain, and Piedmont). The project also produced state-specific crash type proportions.
