Single Summary of Transit Report

The Single Summary of Transit report (SSoT) is published annually by the Federal Transit Administration (FTA) to describe the state of public transit using most the most currently available NTD data publications. It aggregates the data submitted to the National Transit Database by public transit agencies across the country, grouping and summarizing along relevant identifiers that might not otherwise be available using other NTD data publications.

The main goal of the SSoT is to present and summarize transit data in an easy-to-read format and provide a clear overview of public transit in the United States in terms of service provided and consumed. It also displays trends in key transit metrics over at least the last decade. The SSoT is the successor to the National Transit Summaries and Trends (NTST), which was published for report years 1999-2021. The archive of NTST publications may be accessed here.
