Abstract:Rural low-volume roads (LVRs) are an integral part of the highway system as they provide connectivity to rural areas. Low traffic volumes and the random and sporadic nature of crash occurrence over LVR networks pose challenges in using the conventional crash-based network screening methods. Therefore, the objective of this research project is to develop an effective and practical network screening method for Montana LVRs. To that end, six tasks were successfully completed in this project including literature review, developing method assessment criteria, state of practice survey, assessment of network screening methods, developing network screening method for Montana LVRs, and the economic analysis of the new network screening methodology. Methods and findings from each task are detailed in this report along with a set of recommendations for safety management on LVRs and the implementation of the new proposed network screening methodology.
