Service Delivered
Service Delivered measures the percentage of scheduled buses that are actually provided during peak hours.
Service Delivered
Service Delivered measures the percentage of scheduled buses that are actually provided during peak hours. Service Delivered (sometimes referred to as throughput) measures our ability to deliver the scheduled service. It is calculated as the percentage of scheduled bus trips that are actually provided during peak hours. Service Delivered is measured at the peak load point, which is the stop on the route where the bus is most crowded, using GPS tracking data from Bus Time, as well as bus depot operations records.
Bus Speeds
Bus Speeds are calculated as a bus’s average end-to-end speed along a route.
Bus Speeds
Bus Speeds are calculated as a bus’s average end-to-end speed along a route. Bus speeds measure how quickly buses travel along their routes. Speeds are calculated as the average end-to-end speed along a route using Bus Time data.
Additional Bus Stop Time
Additional Bus Stop Time is the average time that customers spend waiting at a stop beyond their scheduled wait time.
Additional Bus Stop Time
Additional Bus Stop Time is the average time that customers spend waiting at a stop beyond their scheduled wait time. Additional Bus Stop Time (ABST) is the average added time that customers wait at a stop for a bus, compared with their scheduled wait time. The measure assumes customers arrive at the bus stop uniformly, except for routes with longer headways, where customers arrive more closely aligned to the schedule. ABST (sometimes referred to as Excess Wait Time) is a new indicator for the MTA, but is considered an industry best practice worldwide. ABST is measured using customers’ MetroCard swipes on buses combined with GPS tracking data from Bus Time. This indicator is likely to be refined and enhanced over time as the MTA gains experience integrating the latest technology.
Additional Travel Time
Additional Travel Time is the average time customers spend onboard a bus beyond their scheduled travel time.
Additional Travel Time
Additional Travel Time is the average time customers spend onboard a bus beyond their scheduled travel time. Additional Travel Time (ATT) is the average additional time customers spend onboard the bus compared to the schedule. ATT (sometimes referred to as Excess In-Vehicle Travel Time) is a new indicator for the MTA, but is considered an industry best practice worldwide. ATT is measured using customers’ MetroCard swipes on buses combined with GPS tracking data from Bus Time. This indicator is likely to be refined and enhanced over time as the MTA gains experience integrating the latest technology.
Customer Journey Time Performance
Customer Journey Time Performance is the estimated percentage of customers’ trips that are completed within 5 minutes of the scheduled time.
Customer Journey Time Performance
Customer Journey Time Performance (CJTP) estimates the percentage of customer trips with a total travel time within 5 minutes of the scheduled time. It is equivalent to the percentage of customer trips with Additional On Bus Time (AOBT) + Additional Travel Time (ATT) less than 5 minutes. See the pages for APT and ATT for more information on how they are calculated. Like AOBT and ATT, CJTP is estimated for each individual bus a customer uses in their journey, not all trains in their journey combined. See Help page for more information.
Mean Distance Between Failures
Mean Distance Between Failures reports how frequently bus mechanical problems cause delays.
Mean Distance Between Failures
Mean Distance Between Failures (MDBF) reports how frequently car-related problems such as door failures, loss of motor power, or brake issues cause a delay of over five minutes. It is calculated by dividing the number of miles train cars run in service by the number of incidents due to car‐related problems.
Passenger Environment Survey
The Station Passenger Environment Survey Key Performance Indicators measure station comfort and convenience.
Station Passenger Environment Survey Key Performance Indicator (PES-KPI)
These indicators combine the results of surveys of a number of different aspects of station condition in three categories:
- Physical Appearance - Is the station clean and free of graffiti?
- Equipment - Are MetroCard vending machines, turnstiles and station attendant booths in working order?
- Information - What service information is available to our customers to help ease their commute? Are there maps easily visible and in good condition? Are Transit employees available, in proper uniform and able to provide customer assistance? Is the signage clear and up‐to‐date?
Station Environment PES-KPI is reported for weekdays only. Due to statistical variations in the monthly surveys, this number is reported as a 12-month average, available by borough.
Wait Assessment
Wait Assessment measures how regularly buses are spaced.
Wait Assessment
Wait Assessment (WA) measures how evenly buses are spaced. It is defined as the percentage of actual intervals between buses that are no more than three minutes over the scheduled interval for the morning (7 am to 9 am) and afternoon (4 pm to 7 pm) peak periods and no more than five minutes over the scheduled interval for the rest of the day. This measure provides a percentage of buses passing the standard, but it does not account for extra service operated, it is not weighted based on how many customers are waiting for buses at different stops, it does not distinguish between relatively minor gaps in service and major delays, and it is not a true measurement of time customers spend waiting at stops.
