What it is Filled
A fare is the price charged for transporting a passenger, typically determined by the journey, service, passenger category, and conditions of travel.
In scope
- Published or quoted charges for passenger transport
- Journey, service, passenger and sales conditions determining applicability
- Fare calculation, currency, price components and rounding
- Travel rights and restrictions attached to the fare
- Effective dates, availability and evidence supporting fare terms
Out of scope
- Tickets, passes and other credentials that evidence travel entitlement
- Transport services, routes, timetables and vehicle operations
- Bookings, seat inventory and passenger records
- Payment transactions, settlement and accounting
- Freight rates and charges unrelated to passenger transport
- Fare meaning food, a passenger or another lexical sense
Why it exists Filled
Enable an agent to identify a passenger transport fare, assess its applicability and current validity, and determine permitted pricing, purchase and use actions.
Distinguishing features Filled
- It specifies a charge or pricing rule for passenger transport, rather than a general product price.
- A fare can exist before a ticket is issued; the ticket evidences entitlement rather than defining the fare itself.
- A fare can apply to multiple departures or journeys, whereas a booking concerns a particular reservation.
- Its amount can be fixed or calculated from conditions such as zones, distance or time, so an amount alone does not identify it.
- A fare class label identifies a category only when linked to actual pricing and applicability terms.
What robots and AI may and may not do Filled
Must not
- Charge or quote a fare that differs from the published tariff without disclosing it.
- Hide mandatory fees until the end of a booking.
- Help a passenger evade a fare or use another person's concession.
- Set fares that discriminate by personal characteristics the law protects.
Only with a human decision
- Buying a ticket with the passenger's money.
- Issuing a penalty fare or refund decision.
May
- Quote fares from the operator's published tariff with conditions and date.
- Compare fare options for a passenger who asks.
- Explain discounts and concessions a passenger may be entitled to.
Moral aspects Filled
- Transport fares decide who can reach work, school and care.
- Opaque pricing exploits passengers who cannot compare.
Who is affected
- Passengers
- Low-income travellers
- Transport operators
Owners Filled
Steward
The transport operator or the authority that sets the tariff.

Open questions
- Does the originating registry record confirm that fare means a passenger transport charge rather than food, a passenger or another sense?
- Does an existing Vercy world model already own passenger transport fares or a broader pricing concept that this entry should reference?
- Should this registered thing encompass reusable tariff rules and individual quoted fares, or should quotes be represented only as related instances?
- Where does the registry place the boundary between fares, ticket products, subscriptions and passes that bundle transport with other services?
- Which authoritative transport tariff sources should establish the initial terminology and treatment of dynamic pricing, transfer credits and fare caps?
