Zurich 2002-2020
AWEL, a governmental agency of the Canton of Zürich, Switzerland, has been using Opus Remote Sensing Devices for 18 years, to study the real-world emissions from motor vehicles in Zurich. Their constant work represents the best continuous evaluation of road traffic emissions in Europe. AWEL began using RSD systems with close support from Opus, but soon had complete autonomy to use them independently. In this way, AWEL rents the equipment when needed with greater flexibility. This type of collaboration is now replicated with other international partners.
The methodology employed by AWEL is unique. Every year they place the Opus RSDs in the same road, for a period of about 4 to 6 months. Only 2 locations have been used. As the emissions from motor vehicles driving in one location are different from those in another, this methodology allows the geographic variability to be eliminated. This way of assessing emissions over time allows for the identification of market trends, checking whether the emissions from vehicles are reducing year by year as they should.
