In a pilot study being carried out by the Department of Applied Environmental Science (ITM) at Stockholm University, four taxis have been equipped to measure pollution and particulate matter. Instruments fitted to the roof of the taxis undertakes measurements which are then cross referenced with the cars' GPS as they travel around Sweden's capital.
