Modelling of Sub-micrometer Particle Concentrations in Free-flowing Freeway Traffic, Brisbane Australia: Some Empirical Results
McGregor, Fraser A., Ferreira, Luis, & Morawska, Lidia (2003) Modelling of Sub-micrometer Particle Concentrations in Free-flowing Freeway Traffic, Brisbane Australia: Some Empirical Results. Transportation Research Part D: Transport and Environment, 8(3), pp. 229-241.
As road networks become increasingly more congested, environmental concerns relating to emissions from motor vehicles assume a higher significance. This study found that road side concentrations of particles produced by freeway traffic in Brisbane, Australia, is primarily dependent upon of traffic flow differentiated into fuel type, and wind speed. The analysis differentiates between diesel and petrol vehicles, and finds that particle concentration is very sensitive to the proportion of diesel fuelled vehicles. A 20% increase in diesel vehicles can produce an 18% increase in particle concentrations compared with a 2% particle increase for the same number of additional petrol vehicles.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
