Comparable data on travel times and distances by different travel modes are frequently called for in land use and urban planning. Here, we present the creation process and the content of a newly opened dataset called the Helsinki Region Travel Time Matrix, made available via Helsinki Region Infoshare service. The dataset presents modelled travel times and trip lengths by car, public transport and walking for the capital region of Finland. The multimodal travel times and distances have been calculated between 13 000 gridded (250 m) data points over the study area. The modelling is made with in-house tools and based on various open data sources, including Digiroad, Journey Planner, and OpenStreetMap, accompanied with ancillary data. In addition to describing and evaluating the dataset, this paper pioneers scientific data description article in Terra. It links to the movements for the openness of research data, open democracy and more transparent planning that highlight the responsibility of researchers to share their data.
