The Strategic Intermodal System (SIS) was designated for the purpose of planning for and investing in a multimodal system of transportation facilities and services of statewide and regional importance. Highways designated as SIS facilities are generally part of the Florida Intrastate Highway System (FIHS). The FIHS program, now a subset of the SIS, aims to preserve regional and statewide mobility through development and improvement of a system of highways with strict access controls. All segments of the SIS and FIHS are planned to be brought into compliance with system criteria and standards within a 20-year period. Communities along these systems often struggle with the transportation impacts of development. Toward that end, the Florida Department of Transportation (Department) is interested in advancing corridor management practices and state and local coordination in corridor management on critical Strategic Intermodal System facilities, and other important state highways in Florida. The purpose of this research was to investigate corridor management practices of local governments and coordination efforts between local governments and the Department on the selected Strategic Intermodal Systems facilities.
