Ranking Formula

In accordance with S&H Code § 2452, the Commission is responsible for establishing criteria to be used in determining the priority of projects nominated for separation or alteration. The Commission does so using formulas initially developed by the Commission in 1975, but modified since that time. There are two formulas used: 1) One for ranking projects proposing new grade-separation structures for existing crossings; and 2) One ranking projects proposing alteration or reconstruction of existing structures. We adopted the most recent priority evaluation formulas in OII 07-07-006, issued July 12, 2007, which are contained in Appendix 2 - Priority Index Formulas, to this OII.
