Identification and Characterization of PM2.5 and VOC Hot Spots on Arterial Corridor by Integrating Probe Vehicle, Traffic, and Land Use Data: The purpose of this study is to explore the use of integrated probe vehicle, traffic and land use data to identify and characterize fine particulate matter (PM2.5) and volatile organic compound (VOC) hot spot locations on urban arterial corridors. An emission hot spot is defined as a fixed location along a corridor in which the mean pollutant concentrations are consistently above the 85th percentile of pollutant concentrations when considering all other locations along the corridor during the same time period. In order to collect data for this study, an electric vehicle was equipped with instruments designed to measure PM2.5 and VOC concentrations. Second-by-second measurements were performed for each pollutant from both the right and left sides of the vehicle. Detailed meteorological, traffic and land use data is also...

GPS use in travel behavior studies has seen increasing acceptance over the past decade, with more than 15 travel surveys conducted since 2000 including a GPS subcomponent. Similarly, accelerometers have become the gold standard for collecting objective physical activity data in health studies. Since 2003, GeoStats has been involved in studies that have deployed both devices in tandem to collect second-by-second travel and physical activity data never before available. This seminar will cover the use of these technologies to address key research questions facing transportation and health professionals.

Dr. Jean Wolf is the president and co-founder of GeoStats, a company specializing in the application of GPS and GIS technologies for the collection, analysis, visualization, and reporting of transportation data. Since the launch of GeoStats in 2000, Dr. Wolf has led all GPS-enhanced travel surveys and physical activity studies conducted by the firm (with more than 20 studies to date). Dr. Wolf has extensive project management, technology, and logistics experience, including 10 years at UPS as an industrial and systems engineer, which makes her uniquely qualified to run complex GPS studies that depend upon the integration of...
