Healthy Outdoor Premises for Everyone

The - Healthy Outdoor Premises for Everyone - is about promoting a healthy urban environment in collaboration with different actors from local government and citizens to businesses and scientists. It deals with advancing the current air quality monitoring network with the help of citizens to gain spatiotemporally accurate information on environmental conditions where people live and travel. Three core districts with varying air quality challenges are in the focus of the project: Jätkäsaari with heavy port-related traffic, Vallila with an active urban street canyon, and suburban Pakila with domestic wood-burning and transit traffic.

Within the project, our action in theDigital Geography Lab is linked to the development of a Green Paths routing tool for aiding individual route choice and facilitating environmental exposure research. The aim is to suggest pleasant walking and cycling routes in Helsinki urban region by reducing exposure to air pollution and traffic noise and increasing exposure to street-level greenery. The Green Paths routing tool is based on near-real-time air quality data derived from the that is developed by the Finnish Meteorological Institute, modelled traffic noise data based on anconducted in the Helsinki Metropolitan Area in 2017, and street-level greenery that is derived from street view images and land cover data .

Find some about the Green Paths routing tool.

Next to developing the routing tool, we aim to understand how the residents in Helsinki region are exposed to health-benefiting and harmful exposures during their daily trips, and how equally accessible pleasant travel routes are for different socio-spatial population groups. We apply bike-sharing and mobile positioning data from Helsinki as a proxy for human mobility. We believe that the Green Paths routing tool and travel-time environmental exposure assessment more broadly can support spatial and transport planning as they allow evaluating the just distribution of access to healthy and pleasant urban travel environments.
