A remote sensing system for carbon monoxide and hydrocarbon vehicle emissions, devised by Prof. D. Stedman's group at the University of Denver, is being evaluated at the Ministry of Transportation of Ontario (MTO) in Toronto. The system was first checked to compare its readings with on-board emission measurements of vehicles as they passed a test point. Since then, it has been operated routinely over several months to measure the emissions of employee and MTO vehicles entering the site and records have been maintained for approximately 1000 vehicles that come in regularly. About 40 of these were tested on the MTO chassis dynamometer using the hot start and stabilized portion of the Environmental Protection Agency (EPA)/Transport Canada urban test cycle.
