NTD Annual Ridership by RTPA#
Provide CalSTA with NTD Annual Ridership by each regional transportation planning authority (RTPA)
Per the SB125 Final Guildelines
Caltrans will provide all RTPAs with a summary report each month that meets the requirements of this statutory provision… For RTPAs with transit operators who do not report monthly data to the NTD, Caltrans will include the most recent annual ridership numbers provided to the NTD.
This report shows general ridership trends by Annual NTD Reporter for California RTPAs. Unlinked passenger trips are reported, as well as the change from the prior year. For example, July 2023’s change would be the change in July 2023’s reported values against July 2022’s reported values.

Frequently Asked Questions#
Q: Which Annual NTD Reporters are in this report? Why are some Reporters missing from an RTPA?
Transit operators/agencies that submit annual reports to NTD are included in this report. Reporters that were previously active reporters, but are currently not, may appear. This may result in Reporters showing zero or partial ridership data in the report.
If a Reporter, type of service, mode, or any combination of, is not a annual reporter or has not reported data since 2018, they will not appear in the report.
Examples:
Reporter A is an annual reporter from 2019-2022, then became inactive and did not report for 2023. Reporter A’s ridership data will be displayed for 2019-2022 only.
Reporter B is an annual from 2000-2017, then became inactive and did not report for 2018. Reporter B will be named in the report, but will not display ridership data.
Reporter C was an inactive reporter form 2015-2020, then became an active full reporter for 2021. Reporter C’s ridership data will be displayed for 2021-present.
