The Office of Planning analyzes capacity needs for the interstate system, including mainlines and interchanges. Mainline capacity needs are based primarily on forecasted volume-to-capacity ratios. Interchanges are evaluated using the Interactive Interchange Management System, which considers roadway and bridge characteristics, geometric design, capacity analysis, safety, and benefit-cost analysis.
