Estimating Effectiveness of Safety Treatments in the Absence of Crash Data

The objective of this project is to develop a procedural guide for using alternative measures of safety in the absence of crash data for developing crash modification factors and functions and other quantifiable measures in the absence of crash data. The new measures will be evaluated against established crash-based measures. In addition, it is expected that the new measures of safety developed will span a range of site conditions, crash types and severity. The procedural guide will support informed decision making during project planning, project development, and other road safety management activities and will also include several use case studies.
