Abstract
In this paper, the CALINE4 software package, designed for calculation of concentrations of carbon monoxide near a
busyroad, is adapted for the analysis of aerosols of fine and ultra-fine particles, generated byvehicles on the road. A
scaling procedure of the CALINE4 package is developed and justified. A new efficient method of determination of the
average emission factor for fine particle emission from the average fleet (one average vehicle) on a given road is also
developed. This method is based on measurements of the average particle number concentration at just one point near
the road.
An example of a specific road in the Brisbane area, Australia, is considered. The average emission factor for vehicles
on this road is calculated to beB4.51014 particle/vehicle/mile. The obtained scaling coefficient is shown to be correct,
and the procedure is directly applicable for the analysis of an arbitrary road with different types of vehicles and their
average speed.
Good agreement between the experimental results and the predicted theoretical dependencies of concentration on
distance from the road clearlyconfirms the applicabilityof the CALINE4 package for the analysis of propagation of
fine particle aerosols from a busyroad. Statistical analysis of the experimental and theoretical results demonstrates that
the concentration of fine and ultra-fine particles approximatelyreduces as a power law in distance from the road.

Citation countsare sourced monthly from Scopus and Web of Science 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.
