TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2386 consists of 21 papers that explore hot-spot identification; the safety and operational benefits of variable speed limits; the effects of public rest areas on fatigue-related crashes; an application of stochastic gradient boosting techniques to enhance reliability of real-time risk assessment; and the feasibility of incorporating reliability analysis in traffic safety investigation; an evaluation of postencroachment time as surrogate for opposing left-turn crashes. This issue of the TRR also examines the behavioral responses of motorists; the identification of primary and secondary crashes; surrogate safety measures; exposure proxies for macroscopic road safety prediction; a crash’s severity based on vehicle damage and occupant injuries; a truck corridor crash severity index; on-duty struck-by crashes; an evolutionary game theoretic approach to rear-end events on congested freeway; and crash databases in Australasia, the European Union, and the United States. Other issues covered by papers in this TRR include the screening of naturalistic driving study data for safety-critical events; a safety evaluation of horizontal curves on rural undivided roads; the heterogeneity of driver behavior with temporal and spatial factors; motion prediction methods for surrogate safety analysis; the identification of crash-contributing factors; and before-and-after evaluation of traffic safety improvements in city of Edmonton, Canada.
