Definition: An industry standard that measures the mechanical reliability of the fleet. It measures the average bus miles between National Transit Database (NTD) reportable mechanical failures i.e., incidents precluding a revenue vehicle from completing its trip, or starting its next scheduled trip. Currently, all mechanical breakdowns are counted as failures, thus exceeding the number of failures reported to NTD.
