MTA Subway Customer Journey-Focused Metrics: Beginning 2020

Additional Platform Time (APT) is the estimated average extra time that customers spend waiting on the platform for a train, compared with their scheduled wait time.

Additional Train Time (ATT) is the estimated average extra time that customers spend onboard a train, compared to the time they would have spent onboard a train if trains were running according to schedule.

Additional Journey Time (AJT) is the estimated average extra time that customers spend on their journey, compared with the scheduled time. It is the sum of the additional time spent waiting on platforms (APT) and the additional time spent onboard a train (ATT).

Journey Time is the average total time a customer spends on their journey waiting for and riding a specific train line.

Customer Journey Time Performance (CJTP) is the estimated percentage of rider trips that are completed within 5 minutes of their scheduled time.

These measures are estimated for each individual train a customer uses in their journey, also known as an unlinked trip, not all trains in their journey combined.

This dataset covers data from 2020 and on. For data between 2015 and 2019, use dataset https://data.ny.gov/Transportation/MTA-Subway-Customer-Journey-Focused-Metrics-2015-2/r7qk-6tcy.

附加平台时间（APT）系指顾客在平台上等待列车的预估平均额外时间，相较于其预定等待时间。附加列车时间（ATT）则是指顾客在列车上额外花费的平均时间，与列车按照预定时间运行时乘客在列车上应花费的时间相比。附加行程时间（AJT）系指顾客在行程中预估的平均额外时间，与预定时间相较。它由在站台等待的额外时间（APT）和在列车上额外花费的时间（ATT）之和构成。行程时间是指顾客在等待和乘坐特定列车线路上的平均总时间。顾客行程时间性能（CJTP）是指预估的百分比，即乘客行程在预定时间前后5分钟内完成的行程。这些指标针对顾客在旅程中使用的每列个别列车进行估算，亦称为未连接行程，而非其旅程中所有列车的总和。该数据集涵盖了2020年及以后的数据。对于2015年至2019年的数据，请使用数据集 https://data.ny.gov/Transportation/MTA-Subway-Customer-Journey-Focused-Metrics-2015-2/r7qk-6tcy。
