Abstract: Motor vehicle has been identified as a major contributor to PM2.5 emissions in cities. However, there is an incomplete understanding of traffic-related particulate air pollution in densely populated countries like Singapore. This thesis explores the use of a modelling study of PM2.5 emissions from motor vehicles using microscopic traffic simulations. The work is motivated by the need to reduce PM2.5 emissions in cities and to improve urban air quality. This preliminary work was carried out for the first time in Singapore to present detailed measures of estimating emission factors of PM2.5 from traffic simulations. It utilizes three model types, (i) traffic simulation model (VISSIM), (ii) traffic emission model (MOVES), and (iii) air quality dispersion model (AERMOD), a modelling sequence to predict concentration of PM2.5 from vehicles near roadways. This research fully utilizes the traffic simulation data to generate PM2.5 emission rates and further predict PM2.5 concentrations contributed by vehicle emissions.
