Daily
transit aggregation
Transitous processes public transport feeds daily. Actual operators, modes, licences and update dates are disclosed per feed in the Transitous source catalogue.
Transitous sources ↗Data inventory
Source, unit, version — and limitation.
This inventory describes the datasets Farleda currently calls or embeds. It avoids blanket coverage promises: availability, licence and freshness can vary by upstream source and by route.

Operational coverage
What the current implementation can query — without implying universal availability.
Per feed
operator coverage
Farleda can route only services present in the upstream feeds at query time. It does not claim every European operator or every journey is covered.
Transitous documentation ↗Rolling
airport dataset
Farleda downloads medium and large airports with IATA codes from OurAirports. The publisher places the data in the public domain and gives no accuracy or fitness warranty.
OurAirports data ↗31
canonical grid countries
The embedded annual snapshot contains EU countries plus selected European neighbours. UK is stored canonically as GB; an internal UK alias is excluded from the displayed count.
Farleda grid API ↗9
transport modes
Nine calculation modes with explicit activity units. Car uses vehicle-kilometres; public transport and flights use passenger-kilometres.
Farleda modes API ↗On demand
places and stays
Points of interest and accommodation candidates are queried from OpenStreetMap services. Results depend on OSM completeness and upstream availability.

Current emission-factor catalogue
Rounded values used by the application. DESNZ 2026 factors are designed for UK activities; Farleda discloses their use as planning proxies for European journeys. These operational factors are not a complete well-to-wheel inventory.
| Mode | Current factor | Range in app | Accounting note |
|---|---|---|---|
| Short-haul flight | 128 g CO₂e/pkm | 126–189 | DESNZ 2026 average passenger with radiative forcing; range economy to business class. |
| Long-haul flight | 153 g CO₂e/pkm | 117–339 | DESNZ 2026 average passenger with radiative forcing; range economy to business class; first class is higher. |
| Average car | 166 g CO₂e/vehicle-km | 55–280 | Direct vehicle operation. Farleda counts one vehicle per four travellers, rounded up. |
| Coach | 39 g CO₂e/pkm | — | DESNZ 2026 published average occupancy. |
| National rail | 31 g CO₂e/pkm | — | DESNZ 2026 national-rail factor; used when a grid-derived electric factor is unavailable. |
| Electric rail model | 28 g CO₂e/pkm | 4–60 contextual | Static UI default. Runtime factor can be grid-derived as g/kWh × 0.09 kWh/pkm; 4–60 spans the displayed FR–PL snapshot. |
| Ferry | 113 g CO₂e/pkm | 19–129 | DESNZ 2026 average passenger; range foot passenger to car passenger. |
| Bicycle | 0 direct | — | Zero direct operational emissions in Farleda; lifecycle and food-energy effects are outside scope. |
| Walking | 0 direct | — | Zero direct operational emissions in Farleda; lifecycle and food-energy effects are outside scope. |
Platform metrics
Public aggregates generated server-side; they do not expose individual trip or account records.
trips planned
Count of stored trip_generated platform events. It can include trips later deleted.
Modelled CO₂e difference
Sum of stored comparison values on trip_generated events. New group comparisons use max(0, distance in km × travellers × 128 ÷ 1,000 − group trip emissions in kg CO₂e). Historical events are not automatically recalculated; this is not proof of avoided travel or a homogeneous impact series.
kilometres planned
Sum of total itinerary kilometres recorded on trip_generated events. Individual legs can use Transitous geometry, OSRM distance or a disclosed great-circle fallback.
public-transit mode share
Share of generated trips whose dominant recorded mode is rail, coach or ferry among trips with a non-null dominant mode.

Freshness and licence boundaries
Published cadence or actual implementation behaviour; no invented refresh promises.

Public read APIs
Versioned JSON endpoints exposed by the Next.js application. Availability depends on the app deployment.
- GET /api/public/v1/modes.jsonOn release
Mode factors, units, ranges and distance-plausibility rules.
- GET /api/public/v1/grid.jsonOn release
Annual country snapshot, fallback and 0.09 kWh/pkm assumption.
- GET /api/public/v1/metrics.jsonCached 1 h
Aggregate platform metrics generated from the current database.
- GET /api/public/v1On release
API index, endpoint descriptions and OpenAPI link.
These listed GET endpoints currently return Access-Control-Allow-Origin: * and require no authentication. Farleda does not publish a universal 10 req/s guarantee. Passport verification is a separate rate-limited POST endpoint — the browser form for it lives on the passport verification page; enterprise limits belong in a service agreement.
Need operator-specific data?
Measured rolling-stock energy, verified passenger counts, fares and service-specific grid procurement are not inferred. For a pilot that supplies these inputs, contact hello@farleda.eu — every other address is listed on the contact page.
