Open data

Apart from our own pilot data, Helsinki and Finland provides you access to abundance of high-quality data on mobility, traffic, air quality and you name it. For free. 

Jätkäsaari pilot data

West Harbour traffic situational picture and ferry arrivals

Traffic situational picture solution developed by Infotripla integrates data from several sources, including vehicle calculation sensors, to provide tools and increased awareness for traffic management to address traffic peaks resulting from the arriving ferries. Related open data and APIs are available at

Data includes:

  • Incident and roadwork information
  • Route suggestions out from the harbour
  • Port vehicle data

Jätkäsaari Smart Junction

Jätkäsaari Smart Junction project produces data on traffic fluency through cameras and radars installed at the bottleneck intersection of Mechelininkatu/Hietalahdenkatu and Jätkäsaarenlaituri. This data feeds to further research on possibilities to improve traffic fluency with the help of traffic signal optimization based on the application of AI.

More information about the open radar data and requesting access here.

Data from the junctions includes:

  • Lane-specific vehicle counts
  • Travel times
  • Stops
Jätkäsaari Smart Junction data sources (installations during 2020 and 2021).

Last 50m data for logistics

The New solutions in city logistics 6Aika project has collected detailed data on routes to buildings and entrances (including barriers, steps). The purpose of the data is to make it easier to find the right entrance and to speed up the delivery of goods, for example. The data is stored and available in OpenStreetMap and for demonstration purposes an example application was created. It visualises entrances and routes of last 50 meters to them. In addition to the navigation application, another (open source) application, Open Logistics Map (OLMAP), is available for collecting such data. 

For more information about project that worked on the topic, read more about the project in Finnish Logistiikan saavutettavuusdata or in English Logistics accessibility data. A final report for the project can be found from Tieke’s web site here.

Data in the Jätkäsaari area (West Harbour)

You can find a detailed report done in the NSB CoRe project in 2017 regarding the Helsinki West Harbour Data and Interfaces here. The inventoried data and APIs cover both static and dynamic sources.

National data

Digitransit (regional and national)

Digitransit ( is a journey planning platform available regionally, nationally and as open source code. All interested parties are welcome to contribute in the development of the service.


Digiroad ( is a national database that provides comprehensive and up-to-date information of the Finnish road and street network. It includes the road geometry and road attribute data. The data is available free of charge and can be used for development and commercialization of transport and mobility services.


Digitraffic ( provides REST/JSON and WebSocket APIs for road, rail and marine traffic information in Finland.

The open data APIs include, for example:

Road traffic (

•   Traffic Measurement System data (450+ measuring stations)
•   Current free flow speeds
•   Traffic disorders
•    Weight restrictions
•    Roadworks
•    Road weather stations, cameras and forecasts

Rail traffic (

•    Routes and schedules
•    Timeliness (real-time and historical)
•    Train locations
•    Train composition (wagons, locomotives)
•    Services on time

Marine traffic (

•    Warnings
•    Schedules
•    Vessel location AIS
•    Vessel and harbour metadata

National Access Point

The Finnish national open transport services catalogue (National Access Point, (, is where transport service providers are obliged to submit essential information on their services via machine-readable interfaces. The catalogue is intended for service developers to find transport service information and interfaces. Using the NAP information does not require registration.

Essential information for transport services (e.g. passenger transport services, stations, ports and terminals, vehicle-for-hire services, shared mobility services) includes, for example:

•    Routes
•    Timetables
•    Opening areas
•    Accessibility information
•    Services times
•    Prices
•    Information about tickets
•    Booking and sales channels, payment methods

Helsinki Region Infoshare

Helsinki Region Infoshare aims to make regional information easily accessible to all. It is a web service providing access to open data sources in the Helsinki Region (Helsinki, Espoo, Vantaa and Kauniainen). Much of the data is statistical in nature, covering topics such as transport, housing, constructed environment, maps, economy, population and much more. The data can be used by citizens, businesses, universities, academies, research facilities or municipal administration.

You can find the data and API documentations at:

Examples of mobility-related data sources;

Public transportation

•    Parking payment zones
•    Residential and corporate parking zones in Helsinki
•    Tourist traffic stops and parking places in Helsinki
•    Real-time parking usage data (from parking ticket machines and mobile payment operators)
•    Parking violations issued
•    Pedestrian slip warnings
•    Statistics on traffic accidents
•    Traffic and industry noise zones

City of Helsinki & open source code

From you can find practical details about open source code development and the use of Helsinki’s codebases.

You can also find source code repositories from Helsinki’s GitHub. Related to transport and mobility, it includes for example:

  • Automatic License Plate Reader with emissions data: Solution developed by Reaktor and tested in the fall of 2020 for connecting license plate recognition with vehicle information such as emissions in order to produce anonymous information and statistics about the emissions of passing vehicles.

Map service for viewing information

The City of Helsinki’s map service ( provides a user interface for viewing geographic information and datasets as map layers. It includes, for example, information about the buildings and real estates, streets, bike paths and racks, city plans etc.

Information about the buildings can also be browsed as a different 3D model views of the city as seen in the screenshot below.

Traffic research and statistics in Helsinki

The Transport and Traffic Planning Division monitors the development of traffic in Helsinki. The division calculates vehicle, bicycle and pedestrian traffic numbers annually to be utilized in planning.  Information on the monitored data and statistics can be found here (in Finnish).

Air Quality

The Finnish Meteorological Institute offers open data ( on weather and air quality.

University of Helsinki’s MegaSense program enables solutions by gathering and fusing spatially variable gas and particulate measurements from high-end scientific instruments, commercial air quality transmitters, dense low-cost sensor arrays, and consumer wearables. You can find further information about the specific data sets and APIs here.
