Helsinki Region Travel Time Matrix

Helsinki Region Travel Time Matrix contains travel time and distance information for routes between all 250 m x 250 m grid cell centroids (n = 13231) in the Capital Region of Helsinki by walking, cycling, public transportation and car. The grid cells are compatible with the statistical grid cells used by Statistics Finland and the YKR (yhdyskuntarakenteen seurantajärjestelmä) data set. The Helsinki Region Travel Time Matrix is available for three different years:

Comparisons of the different years can be found in the Gallery section.

The data has been produced by Digital Geography Lab mainly in the MetropAccess Project (2010-2018) at the Department of Geosciences and Geography, University of Helsinki. The project has been funded by the KatuMetro-project and the University of Helsinki.

The data may be used freely (see the licence text below). We do not take any responsibility for any mistakes, errors or other deficiencies in the data.
