Understanding vehicle activity patterns both spatially and temporally is critical for building accurate mobile
source emissions inventories.
Vehicle activity has frequently been characterized using average speed and vehicle miles traveled (VMT), however
advances in modeling of mobile sources have increased the resolution in vehicle activity necessary for using the
new models to their full capabilities. GPS (Global Positioning System)-based vehicle activity datasets are now
becoming increasingly available from several different research programs.
For example, in 2001, the California Department of Transportation (Caltrans) conducted their 2001 California Statewide
Household Travel Survey Program, which contains GPS-based data sets from across the state. Further, the Southern
California Association of Governments (SCAG) carried out a post-census travel survey in 2001, which contains a
number of GPS-datalogger datasets. These and other datasets have been extensively examined, extracting vehicle
activity information for better characterization of vehicle activity. Results from this analysis will be presented,
in particular to improve our understanding of the CO2 emissions impact. |

Matthew J. Barth, Ph.D., is currently director of the Center for Environmental Research
and Technology (CE-CERT). Dr. Barth joined the University of California-Riverside in 1991, conducting research
in Electrical Engineering where his research focuses on applying engineering system concepts and automation technology
to Transportation Systems, and in particular how it relates to energy and air quality issues. Dr. Barth is a member
of the Institute of Electrical and Electronic Engineers (IEEE), Air and Waste Management Association (AWMA), Transportation
Research Board's Transportation and Air Quality Committee, and New Technology Committee, and ITS America's Energy
and Environment Committee. He has also served on several National Research Council (NRC) committees. Current research
interests include Intelligent Transportation Systems, Transportation/Emissions Modeling, Vehicle Activity Analysis,
Electric Vehicle Technology, and Advanced Sensing and Control.
Professor Matthew Barth received his B.S. degree in Electrical Engineering/Computer Science from the University
of Colorado in 1984, and M.S. (1985) and Ph.D. (1990) degrees in Electrical and Computer Engineering from the University
of California, Santa Barbara. |
