Cleaner transport technology most efficient to ensure compliance with 2010 NO_2 limit values in Copenhagen, Denmark

摘要

An integrated traffic and air quality modelling approach was used to assess the impacts of local abatement measures to study compliance with European Union (EU) air quality limit values for NO_2 and PM_(10). The abatement measures included four scenarios: municipal traffic management, toll ring or road pricing, cleaner transport technology as part of an environmental zone, and maximum effect - a combination of the most effective measures. The study showed that obtained traffic reductions were moderate, and could not ensure compliance for NO_2 in 2010 whereas the cleaner technology scenario reduces compliance problems significantly. Few compliance problems are expected for PM_(10).
