ROVER (ROADSIDE OPTICAL VEHICLE EMISSIONS REPORTER)
In 1998,the ROVER project assessed actual in-use vehicle emissions using a remote sensing van equipped to measure exhaust emissions. It also communicated with Albertans about vehicle emissions.
During ROVER I, over 66,000 light duty vehicles were tested in four municipalities.
In 2006 the project was repeated as ROVER II, testing over 50,000 vehicles in Edmonton, Calgary, Red Deer and Canmore. This time the team measured exhaust emissions of carbon dioxide, hydrocarbon, carbon monoxide, nitrogen oxide and particulate matter. ROVER II found emissions per kilometer are falling but vehicle use is increasing.
