Event
TransportationCamp DC 2027
The attendee-run unconference held Saturday January 9 in Washington, DC, the weekend before the TRB Annual Meeting.
TransportationCamp DC returns Saturday, January 9, 2027, run by Transportation for America. Attendees propose and vote on 50-minute breakout sessions the morning of the event, then run them across five session periods in nine to ten rooms, around a mid-morning keynote and a closing reception. T4America says the 2026 edition drew more than 400 attendees and 50 original sessions. The venue has not been announced, and T4America said registration opens in September 2026.
Why it matters for the data layer
This is the informal front porch of TRB week. Data standards arguments, agency tooling complaints and open-data show-and-tell all get aired here without the peer-review filter that shapes what makes it into a TRB paper, which is precisely why the room is more candid about what is broken.
For a practitioner already flying in for TRB the following week, it is the cheapest available read on what peers are struggling with. It sits immediately before the TRB 106th Annual Meeting on this calendar, so plan the trip as one block.
