taxi
Enable an AI agent to recognise a taxi, assess its readiness for a proposed passenger trip and determine which service actions are supported by recorded evidence.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a taxi, assess its readiness for a proposed passenger trip and determine which service actions are supported by recorded evidence.
A motor vehicle licensed and hired, with a driver, to carry passengers on a public-hire or pre-booked trip for a fare, typically metered or otherwise regulated.
It can be Identify the vehicle and verify evidence supporting its taxi role.; Assess whether a proposed pickup mode and journey fit recorded operating permissions.; Match passenger, accessibility and luggage requirements to the vehicle's current configuration.; Request or assign service through a linked booking or dispatch channel when availability supports it.; Inspect fare information and service equipment before proceeding with a trip.; Flag service-limiting faults or identity discrepancies and route them to the responsible operator..
Distinguishing features
Evidence connects the particular vehicle to a taxi role; paint, a roof sign or a driver's assertion alone leaves that role unverified.
Recorded service permissions distinguish its taxi role from private hire, ride-hail-only or private-car use where the applicable jurisdiction makes those distinctions.
Its service role concerns passenger carriage for hire, distinguishing it from a vehicle used solely for goods delivery or private travel.
A vehicle's taxi identity remains separately recordable when it is occupied, reserved or off duty; immediate availability is not the identity test.
The record denotes a physical vehicle, distinguishing it from a taxi company, dispatch application or booked ride.
Scope
+ Vehicle identity and evidence linking it to a taxi role
+ Taxi authorisation scope and vehicle-specific operating restrictions
+ Passenger, luggage and accessibility suitability
+ Physical readiness and current taxi service state
+ Fare equipment, passenger information and service accountability links
- Driver identity, qualifications, employment and working hours
- Operator business structure and fleet management
- Individual bookings, passenger contracts and trip histories
- Road networks, traffic conditions and taxi-rank infrastructure
- Jurisdiction-wide transport rules and tariff policies
- Payment transactions, insurance contracts and maintenance procedures
Characteristics
- Vehicle identity linkage
- Links between the physical vehicle, registration identifiers and taxi authorisation evidence Prevents a permit, booking or complaint from being attributed to the wrong vehicle.
- Taxi role verification
- Verified, unverified, disputed, formerly authorised; with evidence and assessment time Separates demonstrated taxi status from appearance or unsupported claims.
- Authorisation scope
- Applicable authority, authorisation record, validity period, operating area and restrictions Supports assessment of whether the vehicle may perform a proposed taxi service.
- Passenger acquisition permissions
- Street hail, rank pickup, advance booking, dispatch or other locally defined modes; permitted, prohibited or unknown for each A taxi's ability to accept one type of request does not establish permission for every pickup mode.
- Service availability
- Available, reserved, occupied, off duty, unavailable or unknown; with observation time Determines whether the vehicle can be considered for a new request.
- Usable passenger capacity
- Number of usable passenger places excluding the driver, for the current seating configuration Establishes whether the proposed passenger group fits without relying on nominal vehicle capacity.
- Accessibility configuration
- Recorded boarding method, wheelchair accommodation, restraint provision and passenger transfer requirements Supports matching to specific access needs rather than a single ambiguous accessible label.
- Luggage accommodation
- Usable luggage volume in litres and relevant opening or clearance dimensions in millimetres, for the current configuration Helps assess whether luggage and mobility equipment can be carried alongside the passengers.
- Taxi equipment readiness
- Present, operational, faulty, absent, not applicable or unknown for each required service device Identifies equipment conditions that may prevent or constrain taxi service.
- Fare basis
- Metered, fixed, pre-agreed, externally calculated or unknown; linked to applicable terms Makes the basis of the proposed charge inspectable before acceptance.

Taxi identity and permissions Establishes which physical vehicle is being assessed and what evidence supports its taxi role.
Taxi appearance, taxi authorisation and permission for a particular pickup are separate claims that an agent must distinguish.
Vehicle-to-taxi linkage
Connects observed vehicle identifiers to evidence of taxi designation.
Taxi role evidence
Record the evidence supporting taxi status, its association with this vehicle and any conflicting identifiers.
- Which identifiers connect the observed vehicle to the taxi authorisation or designation record? provenance
- What evidence would distinguish this taxi from a private vehicle displaying similar markings? boundary
Service permission envelope
Captures the vehicle-specific applicability of externally defined taxi operating permissions.
Permitted pickups and journeys
Record authorised service modes, geographic or temporal restrictions and unresolved applicability to the proposed trip.
- Which evidence establishes the permitted pickup modes and operating area for this vehicle? provenance
- Does the proposed pickup and journey fit those permissions, or require an additional check? action
Passenger and luggage fit Describes whether this taxi can accommodate the proposed passengers and their belongings.
A taxi can be available yet unsuitable because of seating configuration, boarding requirements or luggage constraints.
Boarding and access
Records the boarding arrangements relevant to passengers with specific access needs.
Accessible trip configuration
Describe the actual access equipment and configuration, including whether travel requires a transfer from a mobility device.
- What boarding aids, clearances and wheelchair accommodation are available and operational? measurement
- Can the passenger board and travel with their stated needs in the current configuration, and what assistance is required? action
Shared cabin capacity
Assesses passenger places and storage together for the intended trip.
Usable trip capacity
Record usable passenger places and luggage accommodation after accounting for occupied space, equipment and configuration changes.
- How many passenger places remain usable with the required wheelchair, child-seat or other equipment configuration? measurement
- Can the proposed luggage and mobility equipment be accommodated without obstructing passenger places, restraints or exits? action
Taxi service readiness Separates willingness and availability to accept a trip from the vehicle's physical ability to carry it out.
An empty taxi is not necessarily available, and an available indication does not establish that the vehicle is ready for service.
Availability and commitments
Interprets taxi availability signals alongside current service commitments.
Acceptance state
Record whether the taxi can accept a new request, using timestamped observations and linked reservation or dispatch evidence.
- What do the vehicle's availability indicator and linked dispatch status report, and when were they observed? provenance
- Is there sufficient evidence to offer this taxi for a new request, given any reservation or current passenger commitment? action
Passenger service condition
Captures vehicle and cabin conditions that affect readiness for the proposed taxi trip.
Service-limiting condition
Record faults, cabin conditions and vehicle-readiness evidence relevant to carrying passengers, with links to inspection or maintenance records.
- What current observations or inspection records identify faults affecting passenger access, restraints, cabin use or vehicle operation? provenance
- Which recorded conditions require the taxi to be withheld from the proposed trip or checked before assignment? action
Fare interface and accountability Makes the taxi's charging interface and responsible service parties identifiable.
An agent needs to establish how the proposed fare is determined and how the vehicle can be traced if service evidence is disputed.
Fare and payment interface
Records the fare basis, applicable equipment and supported payment interface without owning transaction records.
Charge basis and equipment
Link the proposed fare basis to its terms and record the readiness of any equipment needed to calculate, display or collect it.
- What establishes whether this trip uses a meter, fixed fare, prior agreement or external fare calculation? provenance
- Are the fare display and supported payment facilities needed for this trip operational, or is an alternative explicitly supported? action
Service party traceability
Connects the physical taxi to the parties and identifiers needed for service follow-up.
Responsible party links
Record vehicle-specific links to the operator, dispatch provider and relevant oversight contact, preserving uncertainty where responsibilities differ.
- Which evidence links this taxi to the operator or service provider responsible at the relevant time? provenance
- Which vehicle identifier and contact route should accompany a lost-property request, equipment fault report or service complaint? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.
Kinds and varieties
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- hackney carriage / street-hail taxi
- private-hire vehicle / minicab
- ridesourcing / TNC vehicle
- airport taxi
- wheelchair-accessible taxi
- water taxi
- shared taxi / jitney
- autonomous robotaxi
- Which of these kinds and varieties hold for the sense of taxi this model covers, and on what evidence? provenance
What the second pass must settle
- Does this registry entry include motorcycle taxis, three-wheel taxis and water taxis, or only road passenger cars?
- Where jurisdictions distinguish taxis, private-hire vehicles and ride-hail services differently, what evidence and terminology should determine inclusion?
- Should a permanently decommissioned taxi remain an instance of this model with a former role, and what ends its active taxi identity?
- Which sources can authoritatively establish vehicle-specific permissions and availability, and how should conflicting or stale evidence be handled?
- Which accessibility, fare-equipment and passenger-service requirements apply in each supported jurisdiction, and how should those external requirements be linked?
