Step 4: Rank by TPCI

The TPCI ranking formula is needed to distinguish between crossings meeting the same number of warrants in Step 3. TPCI is a formula that evaluates and weights the following factors:
  • Crashes in the past five years.
  • Trains per day.
  • School buses per day.
  • Number of railroad tracks at the crossing.
  • Train speed.
  • AADT.
  • Presence of nearby traffic signal.
  • Heavy vehicles per day.
  • Presence of nearby intersection (non-signalized).
  • Highest roadway approach speed limit at the crossing.
  • Crossing angle with roadway.
  • Presence of humped or dipped crossing.
The crossing prioritization process currently does not include stopping distance or sight distance information due to a lack of existing data.
