AtB

What AtB does

AtB AS is a publicly owned mobility company serving as the statutory public-transport authority for Trøndelag county in Norway, with headquarters at Prinsens gate 39, Trondheim. The firm is 100% owned by Trøndelag Fylkeskommune and operates under a public service mandate to plan, procure, market, and organize transport across the entire county. AtB does not run vehicles itself; instead, it contracts operators including Vy Buss, Boreal Buss, Tide Buss, Torghatten Midt, Fjord1, Fosenlinjen, and Trøndertaxi to deliver bus, tram, express boat, ferry, and on-demand services, while reselling these to passengers and capturing the spread between procurement cost and ticket revenue.

The product surface is anchored by the AtB mobile app, a multimodal platform integrating journey planning, real-time departures, ticket purchase, the t:kort RFID travel card, AtB Bestill on-demand minibuses, HjemJobbHjem employer accounts, and third-party mobility services including Trondheim Bysykkel, Dott and Voi e-scooters/e-bikes, Hyre car sharing, and TRIPS ridesharing. The cloud-hosted platform (Entur for national journey data, Google Cloud for authentication, PostHog for analytics) collects GPS-based travel-habit data via Bluetooth beacons and consent-based phone positioning, feeding network planning and partnerships with research bodies such as TØI. Sub-brands extend into Samkjøring carpooling, Reisehjelp accessibility assistance, AtB Bonus loyalty, the Elektrisk vei inductive-charging pilot at Sandmoen, and event-driven services (Ski-VM 2025, RussBuss, festivals).

Revenue is generated from a mix of regulated farebox sales (single tickets, 7- and 30-day passes, student and youth tickets, group tickets), public subsidy from Trøndelag Fylkeskommune, Miljøpakken co-funding for transport-infrastructure and modal-shift projects, employer B2B contracts under HjemJobbHjem, on-demand booking fees redistributed to carriers, and travel-guarantee penalty revenue. Pricing is set annually by the county; a 150–200 NOK reduction on 30-day tickets took effect May 1, 2026, and cash onboard sales were eliminated on May 4, 2026 in favor of contactless card and app payment. The end customer base is the general public of Trøndelag — commuters, students (25,000 daily school-transport pupils, 3,800 with individually adapted transport), elderly and accessibility-needs riders, employers, and visitors — distributed broadly enough that end-customer concentration is low, while single-owner (county) and operator-counterparty concentration create moderate structural dependency.

Revenue model

1. Ticket sales (fare revenue): AtB generates the majority of commercial revenue from ticket sales across all transport modes — bus, tram, express boat, and ferry — sold via the AtB app, online store, onboard vehicles, at service counters, via SMS, and at ticket machines. Ticket products include single tickets, period passes (30-day, 7-day), student and youth tickets, and group tickets.
2. Transport procurement from operators: AtB is the public-transport authority for Trøndelag county. It purchases transport services from third-party operators (bus companies, ferry operators, taxi companies) and resells these to passengers. The spread between procurement cost and ticket revenue constitutes a core revenue stream.
3. HjemJobbHjem employer scheme: AtB sells commute tickets to employers in the Miljøpakken zone (Trondheim area) under the HjemJobbHjem program. Employers subsidize employee commutes, and AtB receives revenue from employer account contracts and ticket sales credited to those accounts.
4. Public subsidy (fylkeskommune): AtB is a wholly owned subsidiary of Trøndelag Fylkeskommune (Trøndelag County Authority). As the regional mobility authority, it receives public funding to plan, organize, purchase, and market public-transport services across the county. This subsidizes operations and enables reduced ticket pricing.
5. Shared-mobility integration fees: AtB integrates third-party micromobility (e-scooters, e-bikes) and car-sharing services into the AtB app, taking a commercial or data-advantage role. Trondheim Bysykkel usage is handled via the app, with AtB accounting for approximately half of all city-bike trips. No explicit commission model stated but commercial benefit is implied through increased app engagement and ticket sales.
6. AtB Bestill booking fee: On-demand transport service (AtB Bestill) generates revenue through fare collection from passengers who book rides. Fares are collected by AtB and distributed to operating carriers (Trøndertaxi, Vy Buss, Boreal Buss, Tide Buss, Agder Kollektivtrafikk).
7. Travel guarantee processing fees: Revenue is generated indirectly through fines collected for fare evasion ( gebyr / surcharge for traveling without a valid ticket). AtB processes refund claims for travel guarantees and retains fine revenue on upheld penalty notices.

Direct peers

• Ruter: Ruter is the public transport authority for Oslo and Akershus, Norway's largest metropolitan region. Operates the Ruter-app integrating bus, tram, metro, and ferry ticketing with shared mobility — the closest functional peer to AtB's multimodal MaaS model, just at much larger scale.
• Skyss: Skyss is the public transport authority for Vestland county (Bergen region), owned by Vestland fylkeskommune. Operates the Skyss-app for bus, light rail, boat, and ferry ticketing across urban and rural areas — directly comparable to AtB as a Norwegian county-level transit authority.
• Kolumbus: Kolumbus is the public transport authority for Rogaland county (Stavanger region), owned by Rogaland fylkeskommune. Operates bus, ferry, and on-demand transport with the Kolumbus-app — directly comparable to AtB's regional authority structure and multimodal offering.
• AtB's county peers (e.g., Brakar, Østfold Kollektivtrafikk): Brakar (Buskerud) and similar smaller Norwegian county transit authorities are direct peers — they share the public-authority model, county ownership, and multimodal ticketing apps, but operate at smaller scale than AtB.
• FRAM: FRAM is the public transport brand operated by AtB on interregional routes across Trøndelag. While not a separate entity, FRAM represents AtB's interregional product line and is functionally equivalent to how Skyss and Kolumbus brand their regional services.

Broad incumbents

• Vy: Vy is Norway's largest transport group, operating buses, trains, and freight. As AtB's contracted bus operator (Vy Buss) for Trøndelag, Vy is both a key partner and a broader incumbent in Norwegian mobility — with capabilities that extend beyond AtB's planning/procurement mandate.
• Boreal: Boreal is a major Norwegian public transport operator running bus and ferry services across multiple regions. As a contracted operator for AtB (Boreal Buss), Boreal represents the operator side of the public-transport value chain where AtB sits on the authority side.
• Entur AS: Entur is Norway's national public transport data and ticketing aggregator, jointly owned by the Norwegian state and public transport authorities (including AtB). Entur sits above AtB in the stack by providing national journey planning across all operators — comparable as a MaaS infrastructure layer.
• Moovit: Moovit is a global MaaS app and data platform owned by Intel, providing multimodal journey planning and integrating with public transit authorities worldwide. Comparable to AtB's app in functionality but operates at global scale as a software layer above individual authorities.

Emerging players

• Transit App: Transit is a third-party multimodal journey planner app with real-time data integration across transit agencies worldwide. While not a Norwegian public authority, it overlaps with AtB's journey-planning and ticketing functions as an alternative app channel for end users.
