Spatio-Temporal Analysis of the Roadside Transportation-Related Air Quality (STARTRAQ) and Neighborhood Characterization

To promote active transportation modes (such as bike ride and walking), and to create safer communities for easier access to transit, it is essential to provide to the public that the consolidated data-driven transportation information. The relevant and timely information from data facilitates the opportunity for improving decision-making processes for the establishment of public policy and urban planning for sustainable growth and promoting public health in the region. For the characterization of the spatial variation of transportation-emitted air pollution in the Fresno/Clovis neighborhood, various species of particulate matters emitted from traffic sources were measured using real-time monitors and GPS loggers at over 100 neighborhood walking routes within 58 census tracts from the previous research, Children’s Health to Air Pollution Study – San Joaquin Valley (CHAPS-SJV). Through this project, we will 1) consolidate the air pollution and positional data together by developing quality assured and controlled methods, 2) examine the changes of transportation pollution by the types of the roads and census tracts, 3) analyze the spatial variability in pollution from transportation using time series analysis, and 4) characterize the neighborhoods to identify the active transportation prone areas within and among the neighborhoods. The project will provide valuable research and training opportunities for educators and students through interdisciplinary collaboration. We will establish the methods of synchronous time-series data along the trajectory for 2D and 3D representation from the Geographic Information System. We will also examine the air pollution by transportation profiles of the area. Finally, we will analyze the transportation and pollution characteristics systemically and disseminate our findings and results in a statistically sound way.
