Abstract: This paper presents a system for modelling traffic flow, estimating vehicle emissions and validating them against remotely sensed and in situ data. The results showed that the queuing model was satisfactory and that the vehicle emissions model was internally consistent. The validation results were inconclusive and point to future important areas of research. Notably, it is necessary to develop a system to predict concentrations (rather than emissions) in time and space.

Keywords: Queuing model, emissions, PM10, remote sensing, in situ data
