Mobile Sources In Urban Networks

Abstract
In Santiago de Chile, as in most megacities of the world, transportation activity
has an important effect on pollutant emissions. In the case of Santiago, 70% of
the total NOx emissions are related to transportation. Likewise, mobile sources
generate 46% of total VOC. Due to this high incidence of mobile sources on
atmospheric pollution, and the need to improve the emission inventory of
Santiago, a better modeling of these effects is required. We incorporate in this
modeling some new aspects, such as the grade of the roads. The methodology
we use is based on the computation of both emission factors, that are a function
of pollutant type, vehicle type and speed; and grade correction factors, which are
a function of vehicle weight, pollutant t
