... 5. Although many states include safety improvements, there appears to be limited use of analytical assessments of safety beyond "looking at crash data." The use of new safety analysis tools and methods, such as road safety audits/assessments, the application of the information in the new Highway Safety Manual, the Interactive Highway Safety Design Model, and SafetyAnalyst, is only just emerging.

... With "perfect" information on these relationships, states will be able to select safety improvements that will yield the largest safety return for the available funds for any specific 3R project or for their entire annual 3R program. This effort would include developing crash prediction models for various design elements under different conditions of road types, volume levels, and other influencing variables, and expanding the database on crash reduction/modification factors for individual safety improvements.
