frontal area of the test vehicle. The emissions factors for a wide variety of roads in southern California ranged from 64 to mg/km. These are consistent with but generally lower than measurements using upwind-downwind techniques. This technique is useful for quickly surveying large areas and for investigating hot spots on roadways. Author(s): Amini, Seyedmorteza | Advisor(s): Venkatram, Akula | Abstract: Near road air quality is a public concern because exposure to elevated concentrations of vehicular pollution is associated with adverse health effects. Roadway design is suggested as a potential strategy to mitigate near-road exposure. The first part of my dissertation describes the development and application of roadway Author: Seyedmorteza Amini. A number of in-depth review articles have been published in the last few years on various issues related to road traffic emissions on topics such as properties and characteristics of non-exhaust emissions (Thorpe and Harrison, ), toxicological impacts of tyre wear emissions (Wik and Dave, ), chemical composition of brake pads (Chan and Cited by: Measuring and Modeling Vehicle Emissions: Methodology and –Interest on how roadway infrastructure design and Impacts on Emissions Measurements on over 20 different vehicles 1, one‐way on‐road trips 4, miles traveled vehicle‐hours.

The freely available program will allow data to be viewed in time and space, as well as providing options to reference the geospatial data in terms of distance to a location of interest (e.g., traffic emissions), incorporate ancillary meteorology data, and overlay web-available regional air quality readings. Other Test Method – Method to Quantify Road Dust Particulate Matter Emissions (PM 10 and/or PM ) from Vehicular Travel on Paved and Unpaved Roads This test method is designed to quantify road dust particulate matter (PM) emissions from vehicles traveling on paved and unpaved roads.

By following the guidelines, air quality analysts can more efficiently determine GAV data input needs and achieve consistency among emissions modeling studies. Summary of General GAV Data Required for Emissions Modeling Regardless of the purpose or requirement for the emissions modeling, the collection or devel- opment of certain model.
