A monthly scan of what actually moved on the data and technology layer of transportation.
This edition runs from roughly mid-July to the first week of August 2026. The thread running
through it is reporting: who has to publish what, in which format, and who reads it. Federal
transit data that used to require a spreadsheet download got a consumer-facing front end,
the shared-mobility spec shipped the release it previewed a month ago, and GTFS-Realtime
resolved a long-standing ambiguity in how service alerts describe time.

## The National Transit Database gets a consumer front end

The FTA launched [Transit Moves America](https://data.transportation.gov/stories/s/Transit-Moves-America/2dbc-47zv)
on July 23, a public dashboard built on National Transit Database submissions. It puts
national safety and security averages next to agency-level figures, separates bus from rail
so systems are compared against their own mode, and shows operating cost per passenger trip
for the 25 largest urban areas. Safety and security figures refresh monthly; accessibility
and efficiency measures refresh annually.

FTA Acting Deputy Administrator Matthew Cahill said the dashboard ["brings key performance
data out of obscure spreadsheets
and puts it in the hands of American transit customers"](https://www.masstransitmag.com/management/news/55393389/us-department-of-transportation-dot-fta-releases-new-transit-moves-america-dashboard-for-transit-safety-security-performance-data).
The collection itself is not new. These are NTD submissions, and anyone willing to download
the annual data products could already work them out. What changed is the distance between
an agency's filing and a rider looking at it, which is now about one click. An annual
compliance obligation and a public comparison built on the same numbers put very different
pressure on the people who prepare them, and that is the part operators should plan around.

## Real-time data availability, as a scored attribute

The dashboard did not appear on its own. It follows a June 4 [request for information on
family-friendly transit](https://www.federalregister.gov/documents/2026/06/04/2026-11220/request-for-information-on-family-friendly-transit),
docket FTA-2026-0232, which asked the industry and the public how service quality should be
assessed across five areas: safety and security, cleanliness, universal accessibility,
real-time service data availability, and system reliability. Comments closed on August 3.

The fourth one is our beat. Real-time service data availability is listed alongside
cleanliness and reliability as a property of the service itself, not as an IT deliverable
sitting behind it. If that framing survives into whatever measurement comes out of the
docket, the practical consequence is that an agency's GTFS-Realtime feed stops being an
optional nicety maintained by one person on the planning side and becomes something the
agency is scored on. Worth watching, though an RFI is the earliest possible stage of
anything.

## MDS 2.1 is out of preview

The Open Mobility Foundation [released MDS 2.1](https://www.openmobilityfoundation.org/mds-new-tools-for-safer-streets/)
on July 20. We covered the preview last month, and the shipped version tracks it: an
endpoint for safety incidents covering collisions, near misses, harsh braking, remote
takeovers, autonomous-driving disengagements, obstructions, theft, vandalism, and unplanned
stops; broader delivery support spanning app delivery, goods, freight, and packages rather
than only sidewalk robots; clearer handling of for-hire autonomous services; and improved
geofencing for real-time digital policy. OMF puts the development at two years and hundreds
of contributions.

Two additions matter more than the headline features. The release adds an external
references mechanism for cross-linking to other specifications, and it adds fixed-route
transit integration with GTFS. Both point the same direction. MDS is being wired to sit
alongside the other specs a city or agency already runs, rather than standing apart as its
own regulatory island.

## GTFS-Realtime learns the difference between telling and happening

A small change landed in the GTFS spec that anyone building alert displays will feel. The
`active_period` field on a service alert was always ambiguous: it could mean the window in
which the alert should be displayed to a rider, or the window in which the service is
actually disrupted. Producers read it both ways, so consumers could not tell which they were
getting.

[Two new fields resolve it](https://github.com/google/transit/pull/546). `communication_period`
is when the alert should be shown for informative reasons, and `impact_period` is when
services are actually affected by the disruption. They are mutually exclusive with
`active_period`, so existing feeds keep working. The change merged June 30 and appeared in
the specification's June revision history on July 9.

Anyone who has tried to build a rider-facing alert display, or to measure how far in advance
an agency warns people about a planned outage, has run into this. A two-week heads-up about a
weekend shutdown and a shutdown currently in progress were the same shape in the data, and
now they do not have to be.

## On the calendar

APTAtech runs August 9-12 in St. Louis, with fare payment, data governance, and cybersecurity
on the program, and it is co-located with the scheduling and operations planning workshop.
MobilityData's International Mobility Data Summit follows on September 22-23 in Montréal.
Both are on our [events calendar](https://its-feed.com/events/).

The usual note on shelf life. An RFI is a long way from a rule, and the first cut of a public
dashboard usually gets revised once agencies see how they look on it. The direction each of
these points is steadier than any single date here.
