Open data

Jätkäsaari pilot data


Traffic situational picture

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.

(API to be added)

Data from the junctions includes:

•   Lane-specific vehicle counts
•   Travel times
•   Stops


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.

Mobility related data in Helsinki and beyond

Traffic research and statistics in Helsinki

National Access Point (national)

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


Air Quality data (local and national)

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.
