Public buses host 38 Trillboards screens in transit corridors — captive commuter audiences in 15–45 minute ride sessions.
Bus DOOH reaches the captive commuter audience in 15–45 minute ride sessions. The audience archetype is commuters and travelers in mixed-group composition; ride-share, telecom, financial services, and food-delivery advertisers see strong measured lift in this category.
Public transit operators contract with Trillboards to host in-vehicle screens. The hardware ships pre-configured for moving-vehicle environments (ruggedized mount, vibration-tolerant) and operates over the bus’s onboard connectivity without operator intervention.
Bus DOOH is one of the most attention-rich captive-audience categories — passengers in 15–45 minute ride sessions have limited alternative media (mobile data may be patchy in transit) and frequently look at vehicle screens. The 38 active Trillboards bus screens are concentrated in two US cities (Long Beach CA, Key West FL) plus international bus markets. Floor CPM of $1.20 USD sits below network mean because public-transit advertising operates under more restrictive creative rules than indoor inventory — alcohol creatives are restricted in many jurisdictions, child-safety standards apply to all routes that include school adjacencies. Buyer demand concentrates in ride-share, telecom, food delivery, and financial services.
Brief (under 2 minutes per impression)
Public transit context — family-friendly creative standards apply; alcohol creatives restricted in jurisdictions with public-transit ad rules.
Five US cities with the highest concentration of public buses on the Trillboards programmatic DOOH network (aggregate count — no per-screen identifiers exposed).
Each screen at public buses 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 public buses category on the Trillboards network averages $1.20 USD floor CPM, 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 public buses specifically via the IAB Audience Taxonomy plus the Trillboards segtax=600 namespace without ever receiving per-screen identifiers in the bid request.

The 38 active screens, 2 countries, 2 US cities, $1.20 average floor CPM 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.
