Methods for Identifying High Collision Concentration Locations for Potential Safety Improvements


The California Department of Transportation (Caltrans) uses Table C and related documents to identify and to investigate locations within the state highway system where a relatively large number of collisions occur. In earlier years, a task force evaluated the process of generating and using these reports and found that there was much room for improvements. A list of recommendations was made. The efforts undertaken within this project is part of the effort to make the process of safety investigations and improvements more efficient and productive. This report summarizes the work carried out in the first phase of Task Order 5215 and it provides guidelines for the second phase of the project.
