Problem
While fresh air, quietness and greenery bring health benefits, then air pollution and excess noise may cause physical and mental health problems such as respiratory infections, cardiovascular disease or stress. Fortunately, a more peaceful, less polluted and greener (= healthier) route may be just slightly longer than the shortest one.
Solution
This tool guides you to take pleasant walks to your destinations in Helsinki. You may compare routes from the shortest to the least polluted or quietest and find your own optimal way. The more you value peaceful and pleasant urban environment, the longer routes you may be ready to take.
Data & methods
Street network data is downloaded from OpenStreetMap (CC-BY-SA) and processed into street network graph with OpenTripPlanner.
Hourly air quality index (AQI) is derived from the FMI-ENFUSER high-resolution modelling system.
Traffic noise data is based on an assessment conducted by the city of Helsinki (CC BY 4.0). It is a modelled GIS data representing typical traffic noise levels.
Green view (i.e. greenery) layer is derived from analyzing Google Street View images (Toikka et al. 2020) and openly available land cover data by HRI.
