(a) An authority’s operating cost per passenger is computed by dividing the authority’s annual operating cost by the passenger trips for the same period.
(b) The sales and use tax receipts per passenger are computed by dividing the annual receipts from authority sales and use taxes by passenger trips for the same period.

(c) The operating cost per revenue hour is computed by dividing the annual operating cost by the total of scheduled hours that authority revenue vehicles are in revenue service for the same period.
(d) The operating cost per revenue mile is computed by dividing the annual operating cost by the number of miles traveled by authority revenue vehicles while in revenue service for the same period.
(e) The fare recovery rate is computed by dividing the annual revenue, including fares, tokens, passes, tickets, and route guarantees, provided by passengers and sponsors of passengers of revenue vehicles, by the operating cost for the same period. Charter revenue, interest income, advertising income, and other operating income are excluded from revenue provided by passengers and sponsors of passengers.
(f) The average vehicle occupancy is computed by dividing the annual passenger miles by the number of miles traveled by authority revenue vehicles while in revenue service for the same period.

(g) On-time performance is computed by determining an annual percentage of revenue vehicle trips of revenue vehicles that depart from selected locations at a time not earlier than the published departure time and not later than five minutes after that published time.
(h) The number of collisions per 100,000 miles is computed by multiplying the annual number of collisions by 100,000 and dividing the product by the number of miles for all service, including charter and nonrevenue service, directly operated by the authority for the same period. In this subsection, “collision” includes:
(1) a collision that involves an authority’s revenue vehicle, other than a lawfully parked revenue vehicle, and that results in property damage, injury, or death; and
(2) an incident that results in the injury or death of a person on board or boarding or alighting from an authority’s revenue vehicle.
(i) The number of miles between mechanical road calls is computed by dividing the annual number of miles for all service directly operated by an authority, including charter and nonrevenue service, by the number of mechanical road calls for the same period. In this subsection, “mechanical road call” means an interruption in revenue service that is caused by revenue vehicle equipment failure that requires assistance from a person other than the vehicle operator before the vehicle can be operated normally.
(j) In this section:
