In 2020, the report for NCHRP Project 23-01, “Assessing and Communicating the Economic and Quality of Life Benefits of Transportation Infrastructure Investment” was provided to the American Association of State Highway and Transportation Officials (AASHTO). The research for that project developed evidence-based messaging that state DOTs are using to raise public awareness of the economic and quality of life benefits of transportation infrastructure investments. The study differed from past research in its explicit focus on benefits experienced in people’s daily lives, for example by gaining more control over one’s time, having a less stressful commute, or having more jobs in one’s community. An illustrated guide provided messages and strategies for integrating them into both routine DOT communications and specialized campaigns. NCHRP 20-24(137) will refine and market-test the messages in a more realistic, practical context than was possible during NCHRP Project 23-01. 
Research Objective
The objective of this research was to build upon the results of NCHRP Project 23-01 to evaluate and refine messages and materials that communicate economic and quality-of-life benefits of transportation infrastructure investments. The research will evaluate customer responses to fully developed communications pieces that incorporate graphics and more specific pitches. These sample communications included both urban-based multimodal messages and rural messages focused on mobility and accessibility. The audience for the research results and products are communications practitioners at state DOTs, as well as agency leadership.
