This issue consists of 13 papers that explore highway safety metrics implementation and evaluation, levels of safety at freeway exits, calibration of Highway Safety Manual predictive models, estimating crash modification factors for daytime versus nighttime work zones, and an evaluation of the Texas Department of Transportation safety improvement index as a prioritization tool. It also examines the effects of underreporting crash data, crash variances estimated by poisson models, modeling of driver decision at onset of yellow light at signalized intersections, roundabout performance, automated detection of spatial traffic violations, identifying and quantifing intersection obstruction and its severity, and workplace simulator for geometric design of rural roads.
