CHAPTER 1
Some Considerations on the Environmental Impact of Highway Traffic
Road transport emissions have straight forward effects on air quality re-quirements, at local, regional and even global scales [1–3]. Transport is re-sponsible for around a quarter of EU greenhouse gas emissions making it the second biggest greenhouse gas-emitting sector after energy generation [4]. Due to the vehicles engine internal combustion and fossil fuels usage, transport has become a significant source of air pollutants including CO, CO2, volatile organic compounds, NOx, NO2, O3, total suspended particles and particulate matter (PM). ...
