The Great Lakes/Baltic Sea Partnership Program
2000 Fellowship Selections
Vida Auguliene’s Fellowship Report
Estimation and Modeling of the Traffic Emissions in Urban Areas
My host institution was the Wisconsin Department of Natural Resources.
The Fellowship period was from October 9 to November 6, 2000. The main goal
of the Fellowship project was to gain knowledge and experience for the
traffic estimation and modeling of traffic emissions in urban areas. Project
objectives included:
-
Investigating how emission inventories should be
constructed in order to be useful for air pollution modeling.
Specifications of emission data focusing on emission factors for mobile
sources;
-
Learning how to use motor traffic models;
-
Using traffic emission data simulation to help
evaluate air quality in the Vilnius area and provide a basis for an air
quality improvement plan for Vilnius.
During my Fellowship I met with specialists from different departments of
Wisconsin DNR, Illinois EPA and US EPA Region 5 in order to gain knowledge
and experience for traffic emission estimation and modeling and other
activities associated with urban air pollution.
I gave a presentation on "Vilnius Ambient Air Quality Management
System" at the Wisconsin DNR Southeast Region in Milwaukee. I also
presented during meetings with the Children’s Health Education Center of
Wisconsin, the Southeastern Wisconsin Regional Planning Commission, and at
US EPA Region 5.
I collected many articles, reports and information related to my work,
which will be used in my future investigation on traffic emissions.
Further research of MOBILE5a, CALQ3HC, ISCST3, UAM, and FIRE, tools for
emission factor usage, helped me to understand the basic principles of
traffic emission estimation and modeling as well as the system of emission
databases and data needed for modeling and air quality management at US EPA.
The comparison of emission factors and traffic characteristics data set
needed for MOBILE5a in US and for COPERT in Europe was done. Similarities
between COPERT and MOBILE5a were noted. COPERT is well accepted in Europe
and is the basis for other applications and could be used for Vilnius
AIRVIRO traffic emission database.
The Bureau of Air Management, WI DNR, is comprised of eight sections,
four of which serve specific "industrial process focuses." All
four of these sections include specialized staff with expertise in permit
engineering, compliance, emission inventory and air quality modeling. I
established contacts with specialists from the Ozone, Combustion Process,
Small Business, Environmental Studies and Monitoring sections.
Knowledge and experience that I have gained through the Fellowship
Program will be applied towards the improvement of the air quality in
Vilnius city.
