Abstract
Energy and transport are indispensable ingredients for economic and social
development. At the same time conventional forms of energy production,
distribution and consumption as well as sustainable transport and mobility
patterns are linked to environmental degradation.
The goal of the work is to develop a decision support system able to help
local administrators in reducing the impact of air pollution due to urban traffic.
The method designed is a framework, which included a transportation planning
tool and a comprehensive model to estimate pollutants emissions. The hourly
traffic flow data is obtained from transportation planning, and the emission
model integrated is based on COPERT methodology. Detailed traffic data have
been collected and analyzed from the city of Seville to test the methodology.
Keywords: CORINAIR, emission inventory, traffic assignment model,
transportation planning.
1 Introduction
Among the sources of air pollution, road traffic is widely recognised to be the
most important and increasing source. Carbon dioxide (CO2) and water vapour
(H2O) are the most significant transport emissions to the atmosphere. When
combustion is incomplete, fuel is oxidised to carbon monoxide (CO) with some
volatile hydrocarbons. Impurities such as sulphur are oxidised mostly to sulphur
dioxide (SO2) or to sulphate during the combustion process. And finally, at high
combustion temperatures, nitrogen is oxidised to nitric oxide (NO) and small
quantities of nitrogen dioxide (NO2) or nitrous oxide (N2O). UNECE/EMEP [7]
estimated road traffic emissions to account for about 54% of CO emissions, 47%
