Abstract:
This issue contains 20 papers concerned with the following aspects of highway safety data, analysis, and evaluation: relationship of traffic density, speed, and safety for setting variable speed limits; relationship of freeway flow parameters and safety for hard shoulder running; computer vision-based safety evaluations; safety intervention models; safety effectiveness of Super 2 highways; interaction of crash occurrence, mountainous freeway geometry, weather, and traffic data; real-time safety evaluation with automatic vehicle identification data; research on safety effects of actions; link between crash severity and crash avoidance maneuvers; roles of vehicle footprint, 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 with focus on police enforcement; discretization of road networks for safety evaluation; application of different exposure measures in 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.
