Road traffic is the most important source of many air pollutants in Sweden.
Environment Quality Standards which prescribe acceptable air quality have
been, or will be, introduced within the current decade. Due to the
environmental influence of road traffic there is a significant possibility to
use traffic management measures in order to reduce the negative environmental
effects of traffic. Efficient design of such measures demands models and
methods for estimation of the resulting air quality. This report presents the
state of the art in environmentally based traffic management. The work
includes a description of the environmental consequences of road traffic and
coming air quality standards. Further more, models for estimation of the
environmental impact of traffic are presented along with examples of possible
traffic management measures for a sustainable environment. Today's air
quality estimation systems are used mostly in pollution level control
applications. Air quality based traffic management may need a more detailed
description of traffic related pollutants. Moreover, the possibility for less
negative environmental impact through traffic management in Sweden is not
clear. Finally, the question of how to choose between a possible improvement
of the environment and other costs needs further investigation.
