Safety interventions (e.g. median barriers, photo enforcement) and road features (e.g. median type and width) can influence crash severities, crash frequencies, or both. Both dimensions—crash frequency and crash severity—are needed to obtain a full accounting of road safety....

The CRF (crash reduction factor), which has credibility that can quantitatively explain effects on traffic accidents in the field of traffic safety, is an important area which can evaluate the safety of roads. In this research, the influence on traffic safety using accident data was...

Many studies focused on the development of crash prediction models have resulted in aggregate crash prediction models to quantify the safety effects of geometric, traffic, and environmental factors on the expected number of total, fatal, injury, and/or property damage crashes at specific...
