Description

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 521: Investment Prioritization Methods for Low-Volume Roads documents current practices used by transportation agencies to make investment decisions about low-volume roads. Current transportation asset management practices for low-volume roads typically use asset condition, traffic, and safety metrics to prioritize investment decisions for preservation, maintenance, repair, and replacement projects. However, these metrics do not fully measure the significant value for the wider economy and society that low-volume roads can provide. This publication also addresses the challenges that decision makers may face to communicate the value of such investments to stakeholders in an era of limited funds and constantly changing demands on the transportation system.
