U.S. transit agencies - 10 largest based on unlinked passenger trips 2021

In 2021, the public transport authority with the highest ridership in the United States was by far the MTA New York City Transit with more than 1.7 billion passenger trips. The Chicago Transit Authority had the second highest ridership at 196 million unlinked trips.A Slow Year For TransitThe numbers for unlinked passenger trips reported for 2021 for the largest U.S. transit authorities may seem large, but the total number of unlinked passenger trips declined significantly from 2019, due to travel restrictions during the COVID-19 pandemic. From 9.92 billion total unlinked passenger trips in 2019, this number fell to 4.71 billion in 2020, a near 50 percent decrease. After 2020, the numbers of unlinked passenger trips look to be on the rise, reaching about 7.11 billion in 2023. Buses Win the RaceOf the 7.11 billion unlinked passenger trips on public transport in 2023, nearly half were by bus. A further 37 percent were by heavy rail. The remaining 14 percent of public transport trips were largely made up of trips by light rail and commuter rail.

于2021年，美国公共交通乘客量最高的权威机构无疑是纽约市交通管理局（MTA New York City Transit），其乘客出行次数超过17亿次。芝加哥交通管理局以1.96亿次的非联程出行次数位居第二。公共交通行业的一年低谷尽管2021年美国最大公共交通机构报告的非联程乘客出行次数看似庞大，但与2019年的数据相比，总出行次数显著下降。由于COVID-19大流行期间的旅行限制，2019年的总计非联程乘客出行次数从99.2亿次降至2020年的47.1亿次，降幅接近50%。2020年之后，非联程乘客出行次数呈现上升趋势，至2023年达到约71.1亿次。公共汽车在竞赛中胜出在2023年的71.1亿次公共交通非联程乘客出行中，近一半是通过公共汽车完成的。另外37%是通过重铁线路完成的。剩余的14%公共交通出行主要由轻轨和通勤铁路完成。
