transport
Let an agent reason about transport as movement with a mode, a route, a carrier, a time and a cost, and separate the activity from the vehicles and the infrastructure.
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
Let an agent reason about transport as movement with a mode, a route, a carrier, a time and a cost, and separate the activity from the vehicles and the infrastructure.
The movement of people, animals or goods from one place to another, by any mode, and the systems, infrastructure and services that make that movement possible.
What it is for: Moving people and goods to where they need to be.
It can be plan a trip or a shipment, across modes; buy or book it, as a service from a carrier; measure it, in passenger-kilometres or tonne-kilometres; regulate it, for safety, emissions and access.
Distinguishing features
An activity and a system, not a vehicle
Defined by mode, route and carrier
Passenger and freight transport are organised and regulated differently
Includes non-motorised movement such as walking and cycling
What it looks like
Vehicles moving on infrastructure: roads, rails, waterways, air routes and pipelines, with stations, ports and terminals where movement begins and ends.
Physical character
speed: 5-900 km/h - from walking to jet aircraft
energy intensity: 0.1-3 MJ per passenger-km - rail and bus low, private car and air high
How it is recognised
A vehicle in motion on a route
Terminals, stops and stations where modes meet
Tickets, bills of lading and timetables as records of the service
Related models
uses - cars, buses, trains, ships and aircraft are separate models
uses - infrastructure is a separate model
is provided by - the operator of the service
is measured by - the standard activity measures
In practice
Families and kinds
by mode: road, rail, water, air, pipeline, cable, active travel
by load: passenger, freight
by service: public, private, shared, on-demand
by scale: local, regional, long distance, international
Identifiers
GTFS feed of routes, stops and trips public transit schedules
UN/LOCODE five-character location code ports and terminals
Standards and regulation
National transport safety regulations by mode
ICAO and IMO rules for air and sea transport
ADR, RID and IMDG codes for dangerous goods
Passenger rights regulations
Failure modes and hazards
Accidents, which are the main hazard of every mode
Delays and cancellations that break connections
Emissions and noise
Dangerous goods incidents

Mode and route How and where movement happens.
Mode and route determine time, cost, risk and rules.
Mode
Road, rail, water, air or other.
Mode used
The mode and vehicle types.
- Which mode and vehicles are used? definition
- Which alternative modes exist for this route? definition
Route
Origin, destination and path.
Route details
The route and its stops.
- What route does this movement follow, via which stops? definition
- What distance and time does it take? measurement
Service and carrier Who provides it and how.
Transport is bought as a service with terms, prices and liabilities.
Carrier
Operator of the service.
Carrier identity
The carrier and its licensing.
- Which carrier operates this service, and under what licence? provenance
- Who is liable if something goes wrong? boundary
Booking and price
Tickets and contracts.
Commercial terms
The price, ticket and terms.
- How is this service booked, and at what price? definition
- What are the rules for changes and refunds? boundary
Performance Reliability, capacity and emissions.
Performance measures let people compare options and hold operators to account.
Reliability
Punctuality and cancellations.
Reliability record
Punctuality statistics.
- How punctual and reliable is this service? measurement
- From which source do the statistics come? provenance
Energy and emissions
Environmental impact.
Emissions estimate
Emissions per passenger or tonne.
- What are the emissions per passenger-km or tonne-km? measurement
- Which method produced that estimate? provenance
Safety and rights Rules protecting people.
Safety rules and passenger rights govern what operators must do.
Safety
Safety rules and record.
Safety regime
The safety rules and incident record.
- Which safety rules apply to this mode and service? provenance
- What is its safety record? measurement
Passenger and shipper rights
Compensation and accessibility.
Rights in force
The rights applying to users.
- Which passenger or shipper rights apply? provenance
- How is a claim made? action
What the second pass must settle
- Should the registry model each mode as a child entry of transport?
- How should multimodal trips be represented?
- Which metrics should the model carry for comparison across modes?
