Transportation agencies must grapple with a broad range of trends and issues that influence and act upon the systems they manage and operate. Issues include climate change, goods movement, changing centers of population and economic activity, and telework, among others.
NCHRP Web-Only Document 345: State Transportation Agency Decision-Making for System Performance: Conduct of Research Report, from TRB's National Cooperative Highway Research Program, depicts the relationships among trends, issues, and system objectives.
The report is supplemental to NCHRP Research Report 1042: State Transportation Agency Decision-Making for System Performance: Practitioner’s Playbook.
