Abstract:

The Highway Safety Manual (HSM) contains safety performance functions (SPFs) that are used in project-level decision-making to estimate the average crash frequency by severity level for existing conditions, alternatives to existing conditions, or proposed new roadways. Because most existing HSM SPFs were developed for states other than Texas, SPF calibration is needed to apply for Texas highways. Calibration is conducted to account for differences in crash reporting procedures, thresholds, driver characteristics, animal population, and weather conditions, among others.
