Influence of temporal variation of traffic volume and composition on air quality in urban areas

The aim of this paper is to investigate the influence of the traffic temporal evolution on the air pollution in urban areas using the city of Thessaloniki as a case study. Data from traffic counts were used and include traffic volume and composition in main roads and intersections of the Thessaloniki city centre.

Based on the specific data, the temporal evolution of the vehicular traffic and traffic composition (passenger cars, buses, heavy goods vehicles and two-wheel cycles) has been examined and presented. The above-mentioned temporal variation of traffic is correlated with the temporal variation of air pollutant concentrations and meteorological conditions in the Thessaloniki city centre (mainly for the primary pollutants) as well as in areas outside the city (mainly for the secondary pollutants). The air quality data include concentrations of carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3) and particulate matter (PM10).

Intra-hourly variations of CO concentrations in Thessaloniki during the rush hours
© Aristotle University of Thessaloniki (6/2009)
Large urban conurbations are suffered from huge traffic due to extensive use of private cars that degrade the quality of life (air pollution, exposure to dangerous pollutant concentrations of both carcinogenic and non-carcinogenic substances, noise pollution, lost traveling time in the cars due to traffic congestion and a consequent number of health problems such as backbone and back affections, nervous breakdown, blood pressure increase, etc.). Congested roads are significant sources of air pollutants.

Publics’ attitude on air pollution in the city of Thessaloniki, Greece

The present work investigates the major environmental problem of air pollution that more or less occurs in the cities, based on publics’ perception. A case study was carried out in the city of Thessaloniki, Greece, in order to present and evaluate the publics’ attitude on air pollution levels in the city.
