Cities that adopt roadside emissions sensors to detect high polluting vehicles, together with an enforcement program to inspect and repair these vehicles, could significantly improve urban air quality, new research shows.
Cities that adopt roadside emissions sensors to detect high polluting vehicles, together with an enforcement program to inspect and repair these vehicles, could significantly improve urban air quality, new research shows.
Vehicle emissions are the most significant source of air pollution in the urban environment worldwide, impacting the climate and the health of millions of people. Reducing air pollution is a key target of the United Nations sustainable development goals.
“Car exhaust fumes contain poisonous gasses such as carbon monoxide, nitrogen oxides, and particulate matter that cause lung cancer, heart failure, asthma and other diseases,” says research co-author, Professor John Zhou from the University of Technology Sydney (UTS).
“Remote sensing equipment uses a sensor and light beam to measure chemical concentrations in the exhaust as a vehicle drives past. A camera records the licence plate, so vehicles can be identified for inspection and repair,” he says.
