This synthesis examines how State DOTs fund, manage, and coordinate the maintenance of Complete Streets infrastructure, including bicycle, pedestrian, and other active transportation facilities. As agencies expand multimodal networks, the report highlights practical challenges such as equipment compatibility, staffing capacity, and ongoing maintenance funding.

Practitioners will find examples of maintenance policies, interagency cost-sharing agreements, and partnership models involving local and tribal governments. The report also identifies strategies for workforce training, equipment procurement, and operational coordination that can help agencies sustain Complete Streets investments over time.

NCHRP Research Report 1164: The Business Case for Knowledge Management: A Guide provides state departments of transportation and other transportation agencies with practical tools to assess and measure the value of knowledge management (KM) initiatives. As experienced staff retire and collaboration across disciplines increases, agencies face growing challenges in preserving institutional knowledge and ensuring effective knowledge transfer. The guide outlines approaches for evaluating how KM practices contribute to improved business processes, workforce development, and organizational performance. It helps agencies articulate the return on investment of KM activities and integrate them into broader performance management strategies.

Accompanying the report, NCHRP Web-Only Document 437: Assessing and Measuring the Business Value of Knowledge Management documents the research effort and provides additional detail supporting the guide’s development.

NCHRP Research Report 1149: Estimating Benefits of Closing Gaps in Active Transportation Networks: A Guide provides practical methods for evaluating the benefits of projects that improve connectivity in walking, bicycling, and rolling networks. Active transportation systems—including trails, sidewalks, bike lanes, and connected roadways—play a critical role in supporting safe, convenient travel for both recreation and everyday trips, yet many communities face fragmented networks with significant gaps. This guide offers accessible analytical approaches that can be applied across diverse geographies and project types, using publicly available datasets and research-based multipliers. Designed for broad usability, the methods rely primarily on national-level data sources to help agencies consistently estimate economic, safety, health, and mobility benefits.

NCHRP Web-Only Document 426, which accompanies the report, documents the development of the guide and summarizes the full research effort behind the recommended methodologies.
