Monograph

This issue contains 15 papers on statistical methods and highway safety performance. Specific topics addressed in this issue include the following: multivariate full Bayesian hot spot identification and ranking; modeling crash rates for a mountainous highway; piecewise linear effects of crash contributing factors; classification of gaps at uncontrolled intersections and midblock crossings; safety impacts of a statewide centerline rumble strip installation program; safety effectiveness of converting two-lane roadways to four-lane divided roadways; and horizontal curvature of rural multilane highways. Additional topics covered in this issue include: calibration factors for crash prediction models; safety effects of pavement widening projects; safety performance functions for urban four-lane divided roads; safety analysis of freeway segments; safety performance function calibration factors; local calibration process of the Highway Safety Manual; and safety performance function arterial segment models.
