MTA Subway Customer Journey-Focused Metrics: 2015-2019

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 between 2015 and 2019. For data from 2020 on, use dataset https://data.ny.gov/Transportation/MTA-Subway-Customer-Journey-Focused-Metrics-Beginn/4apg-4kt9.

附加平台时间（APT）系指乘客在平台上等待列车所需额外平均时间，与预定等待时间相比。附加列车时间（ATT）系指乘客在列车上所需额外平均时间，相较于列车按时刻表运行时乘客在列车上所花费的时间。附加行程时间（AJT）系指乘客在行程中所需额外平均时间，与预定时间相比，它是平台等待额外时间（APT）与列车上额外时间（ATT）之和。行程时间是指乘客在等待和乘坐特定列车线路的平均总时间。乘客行程时间绩效（CJTP）系指预计在预定时间前后5分钟内完成的乘客行程百分比。这些指标针对乘客在旅程中使用的每辆列车进行估算，亦即所谓的非连接行程，而非旅程中所有列车的总和。该数据集涵盖了2015年至2019年的数据。对于2020年及以后的数据，请使用数据集 https://data.ny.gov/Transportation/MTA-Subway-Customer-Journey-Focused-Metrics-Beginn/4apg-4kt9。
