Application developer, we are here for you. On this page, you will find all the information you need about Fintraffic’s open data, the developer community and the utilisation of our interfaces. You can also find instructions on how to import your own data and share it with others. Please also list you application in the Digitraffic service to gain more visibility and users.
We have data, you have ideas – let’s work together and make Finnish traffic the best in the world!
Fintraffic offers developers extensive and high-quality traffic data services.
Fintraffic’s open traffic data services include:
Digitraffic:
- Purpose: Provides real-time traffic data on road, rail and water traffic. The service includes information on the traffic flow and road conditions, disruptions, accidents and road work as well as traffic volumes. Train timetables and real-time locations, train composition details and passenger information are available for rail traffic. The location data of ships used for merchant shipping can also be found in Digitraffic, as well as warning and disruption data for maritime traffic and port schedules.
Technology: Mostly REST and GraphQL interfaces, through which data is usually recovered in JSON format. MQTT/WebSocket connections are also used for real-time data transmission.

Digitransit:
- Purpose: Focusses on data on public transport and, for example, city bike systems, journey planning, timetables and availability information. Provides access to public transport journey planning, real-time timetable information and more. The service also covers Finland’s address information, maps and POI data related to addresses.
- Technology: The service utilises the open-source OpenTripPlanner in journey planning. The Digitransit community is among the most active in its development. For traffic data, Digitransit mainly uses the GTFS, GTFS RT and Siri standards, but compatibility with NeTEx will also be introduced in the future. Provides a GraphQL interface that is used through separate API management
Finap.fi:
- Purpose: National service catalogue for the digital interfaces of mobility services. Mobility service providers, such as public transport operators, taxis, various city bike systems and shared use services, provide the NAP database with a description of their services and data interfaces that could contain stop information, route information or an interface for booking services and payments.
- Technology: The developer API provides access to published services and operator information. The interface provides data in a GeoJSON or JSON format. The service also includes static and dynamic data packages and data publications, which are available mostly in GTFS, GTFS RT, Siri and NeTEx formats. The service also includes a list of traffic service providers’ native developer interfaces.
These traffic information interfaces are designed specially for developers and traffic sector actors so that they can utilise traffic data in the development of their own applications and services. You can find more details in the documentation of each service.
