Information

First up: This is a work in progress, so more information is coming.

This site is the result of a pre-project funded by RFF Nord. The project is a collaboration between Norut, Telenor, Nobina, Tromsø municipality and the Norwegian Public Roads Administration. The project's aim is to test IoT-based sensors for air quality measurements. Two sensors have been mounted on public buses in operating in regular passenger traffic in Tromsø, Norway. Data gathering started in early December 2017, and is as of January 26th 2018 still ongoing.

The visualization is developed by Daniel Stødle. The sensors mounted on the buses were developed by Telenor and Telenor Exploratory Engineering (Arne Munch-Ellingsen, Thomas Langås, Ståle Holberg Dahl, Hans Jørgen Grimstad). Thanks also to Ellen Brox and Per-Egil Kummervold.
