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）是指客户在平台上等待列车的时间与计划等待时间的平均额外时间。附加列车时间（ATT）是指客户在列车上花费的平均额外时间，与列车按计划运行时客户在列车上花费的时间相比。附加行程时间（AJT）是指客户在行程中花费的平均额外时间，与计划时间相比。它是等待平台上的额外时间（APT）和列车上额外时间（ATT）的总和。行程时间是指客户在等待和乘坐特定列车线路上的平均总时间。客户行程时间性能（CJTP）是指估计的百分比，即在预定时间前后5分钟内完成的乘客行程。这些指标是对客户在行程中使用的每辆单独列车进行估算的，也称为未链接行程，而非其行程中的所有列车。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。
