This digest summarizes key findings of research performed under NCHRP Project 20-65, Task 42, Rural Public Transportation Strategies for Responding to the Livable and Sustainable Communities Initiative, by ICF International. For the study, ICF conducted a nationwide survey of state departments of transportation (DOTs) and their rural livability activities; conducted follow-up interviews about grants from the Partnership for Sustainable Communities (PSC); and created a primer highlighting strategies that state DOTs, transit operators, and their partners can use to help rural organizations applying for discretionary grant programs. The strategies discussed in the primer are: (1) Building awareness of PSC resources and livability in rural communities; (2) Providing programmatic and financial support; (3) Creating statewide or regional partnerships; and (4) Encouraging transit coordination at the regional level.
