(a) "additional platform time" means for the subways the average added time that customers spend waiting on the platform for a train, compared with their scheduled wait time.

(b) "additional train time" means for the subways the average additional time customers spend onboard the train, compared with their scheduled on-train time.

(c) "customer journey time performance" means for the subways the percentage of customer trips with an estimated total travel time within five minutes of the scheduled total travel time.

(d) "elevator availability" means percentage of facilities that require the use of stairs and have an operational elevator.

(e) "escalator availability" means percentage of facilities that require the use of stairs and have an operational escalator.

(f) "additional journey time" means for the subways comparison of measured or estimated actual journey time compared to schedule.

(g) "journey time" means for the subways time on platform and the time on train. Journey time is calculated as either actual journey times that customers experience, or as scheduled journey times. Journey time and its components may be based on a manual or an automatically generated sample.

(h) "major incidents" mean (1) for the subway incidents that delay fifty or more trains where a train is considered delayed if it is more than five minutes late or skips planned stops, and (2) for the commuter railroads incidents that delay ten or more trains greater than five minutes and fifty-nine seconds.

(i) "lost time accidents" means a job related incident that results in the inability of an employee to perform full job duties for at least one working day beyond the day of the incident. Rates are based on lost time accidents per one hundred employees.

(j) "employees' lost time days" means for the commuter railroads the total number of calendar days employees' treating medical professionals have determined that they cannot work due to an occupation injury or illness.

(k) "employee lost time rate" means for the commuter railroads the number of occupational injuries or illnesses per two hundred thousand employee hours worked.

(l) "terminal on-time performance" means (1) for the subways the percentage of trains arriving at their destination terminals as scheduled with a train counted as on-time if it arrives at its destination early, on time, or no more than five minutes late, and has not skipped any planned stops, and (2) for the commuter railroads the percentage of trains arriving at their final destination terminals as scheduled with a train counted as on-time if it arrives at its destination early, on-time or no more than five minutes and fifty-nine seconds late. Provided that the percentage of trains not arriving at their final destinations shall include unscheduled cancellations.

(m) "additional data" means (1) for the subways the percentage of trains arriving at their scheduled terminals between four and five minutes after their scheduled arrival time; (2) for the commuter railroads the percentage of trains arriving at their scheduled terminals between four and five minutes and fifty-nine seconds after their scheduled arrival time; and (3) for commuter rails the percentage of cancelled trains. 2. Reporting. The authority shall take all practicable measures to collect, compile and publish meaningful and informative performance metrics for all customer trips provided by the New York city transit authority subways, Long Island rail road and Metro-North commuter railroad on a monthly basis including all applicable performance metrics as defined in subdivision one of this section. If the authority cannot practicably collect and compile any such performance metric for a customer trip type, it may, subject to the approval by the chairman of the metropolitan transportation authority, substitute an equivalent performance metric based on international public transport benchmarking and best practices that comparably measures system performance and service delivery. 3. International benchmarking. (a) The authority shall publish an annual report presenting the authority's performance in comparison with other national and international peer agencies. This report shall include, but not be limited to, the following metrics:

(i) total operating cost per car per mile;

(ii) maintenance cost per car per mile;

(iii) passenger journeys per total staff and contractor hours; and

(iv) staff hours lost to accidents.

(b) The authority shall also provide an annual implementation report to the governor, the temporary president of the senate, the speaker of the assembly, the minority leader of the assembly and senate, and the chairs and ranking members of the transportation and corporations, authorities and commissions committees on or before January thirty-first every year, and publish such report on its website.
