Intersection Safety
In Intersection Safety, you'll learn ...
- Intersection crash characteristics and the link between standards and safety
- Human factors and their relationship to roadway design elements
- How to calculate the expected crash rates (CR) for different scenarios
- Screening techniques to determine if an intersection is safe
- Geometric features related to substantive safety at intersections
Overview
The Intersection Safety course was developed to discuss the issue of safety as it relates to traffic studies and plan design. Despite improved intersection design and more sophisticated applications of traffic engineering measures, the annual toll of human loss due to motor vehicle crashes has not substantially changed in more than 25 years. Perhaps with a better knowledge behind the crash statistics and countermeasures, designers can implement designs with better intersection safety.
Included in the course are human factors affecting intersection safety, calculations predicting safety of intersections and screening techniques. A six-step crash mitigation process is provided to identify high crash locations and identify countermeasures. The designer can use these steps to identify sites with potential safety problems, identify contributing factors and determine appropriate countermeasures to be used in the plans preparation. The countermeasures are discussed in detail and include signing, pavement marking, lighting and signalization features.
The course is designed to provide a basic knowledge of intersection safety from which an engineer can use this information in traffic studies and plan design.
