Description:
Appendix C of this information guide provides information to researchers regarding the general value of research in the road safety field due to its contribution to informed decision-making, as well as the specific value of proposed research in terms of saving money or improving the reliability in allocation of funding using Value of Information techniques. A case study example, structured around roadway lighting, demonstrates an application of the approach to determine a practical dollar value of proposed research that is drawn from the reduced risk of program- or project-related decisions being wrong.
Appendix D of the guide lays out a detailed procedure and discusses several foundational issues for developing crash modification factors (CMF) (i.e., estimating the mean and variance of safety effects resulting from the implementation of a countermeasure). The guide also discusses how to determine the value of proposed CMF research, primarily research with the intent of reducing uncertainty in existing CMFs. Such research may either represent entirely new studies, or rework past studies to clarify and refine the relationships between causal factors and the estimate of the safety effects.
