The purpose of this study was to determine whether acquiring additional limited access right-of-way (ROW) at the time an interchange is built and before the surrounding area is subdivided and developed, is in fact cost effective in light of potential costs and benefits. The study methodology included the following: (1) traffic operations analysis of the interchange with varying configurations of signalized access spacing, (2) safety analysis of interchanges with varied access spacing in Florida, and (3) a cost/benefit analysis of acquiring varying amounts of limited access ROW.
