Highway Safety Data, Analysis, and Evaluation 2012

Overview

TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2280 consists of 20 papers that explore setting variable speed limits; hard highway shoulder running; computer vision-based safety evaluations; safety intervention models; safety effectiveness of Super 2 highways; crash occurrence, mountainous freeway geometry, weather, and traffic data; real-time safety evaluations; and crash avoidance maneuvers.

This issue of the TRR also examines the roles of vehicle footprints, height, and weight in crash outcomes; safety assessment of road network structures; effect of collision aggregation on safety evaluations; integrating observational and traffic simulation models; crash frequency in work zones; discretization of road networks for safety evaluation; crash prediction models; long-term safety trends as a function of vehicle ownership; transferability of safety performance functions; land use entropy and accidents; and advisory speeds.
