DOOH advertising in transit venues reaches an active footprint across the Trillboards network in 4 US cities. Programmatic buyers serve creatives via OpenRTB 2.6 with an average floor CPM of $2.99 USD per thousand impressions, settled daily via signed proof-of-play receipts. The category is part of the 38-venue Trillboards programmatic DOOH inventory served to demand partners worldwide.
Transit venues — airports, buses, train stations — average 3,540 daily impressions per screen on the Trillboards network.
Transit DOOH delivers the highest single-screen impression count of any category (3,540 daily impressions per screen average) because the audience is concentrated and continuous. CPMs are competitive at $2.99 USD, and the audience archetype skews toward commuters and travelers — high-value for telecom, travel, automotive, and financial-services advertisers.
Transit operators — typically port authorities or transit-property managers — host Trillboards screens at platform, gate, and concourse positions. Trillboards handles all programmatic demand wiring and reports aggregate plays monthly without exposing screen-level identifiers externally.
Transit DOOH is one of the most reach-efficient categories in the global out-of-home market because the audience is concentrated geographically (a single rail platform can see 20,000–50,000 daily commuters) and temporally (peak morning and evening windows). The Trillboards transit footprint includes airport, bus, and train-station inventory. The 3,540 daily impressions per screen is the highest of any category on the platform and is driven by audience density rather than dwell time — each individual impression is brief (5–30 seconds) but raw volume is enormous. Buyer demand concentrates in telecom (national carriers), travel (airlines, hotels, travel-tech), automotive, and financial services.

Five US cities with the highest concentration of transit venues on the Trillboards programmatic DOOH network (aggregate count — no per-screen identifiers exposed).
Each screen at transit venues runs the Trillboards kiosk app, which holds an open OpenRTB 2.6 connection to the Trillboards SSP. Roughly every 30 seconds, the device fires an ad request carrying the IAB DOOH inventory descriptor (venue category, geographic bucket, screen format) plus any locally observed audience signals from the on-device CV pipeline — group composition, audience archetype, and attention level — all aggregated and stripped of per-person identifiers before they leave the screen.
Demand-side platforms bid in under 100 ms; the winning creative ships back, plays inside the device's native VAST player, and confirms playback via a signed proof-of-play receipt. Trillboards reconciles those receipts daily against partner-reported numbers (the canonical record of truth for billable impressions) and credits the venue's earner balance monthly. The transit venues category aggregate on the Trillboards network averages $2.99 USD floor CPM and 3,540 daily impressions per screen, numbers that translate directly into the earnings model below.
The Trillboards platform supports both first-party and third-party VAST creatives, OMID-compliant viewability measurement where the creative declares OMID support, and full proof-of-play receipts signed at the device level — meeting the Out of Home Advertising Association of America (OAAA) measurement standards and the IAB DOOH 1.0 specification. Buyers using the Trillboards OpenRTB endpoint can target transit venues specifically via the IAB Audience Taxonomy plus the Trillboards segtax=600 namespace without ever receiving per-screen identifiers in the bid request.

The figures shown here are aggregated from the Trillboards PostgreSQL system of record (table earner_screens filtered by status = 'approved'), joined to the venue taxonomy. Counts reflect the network state at the snapshot date and are rebuilt monthly. Floor CPM numbers are the screen-level minimums; cleared CPMs typically run 20–40% higher depending on demand. Per Trillboards aggregate-only data disclosure policy, no per-screen identifiers, partner identifiers, or device identifiers are published on this page — only the counts and category-level statistics needed for buyer and earner decisions.
