An Extension of Spatio-Temporal Analysis of the Roadside Transportation-Related Air Quality (StarTraq 2021): A Characterization of Bike Trails and Highways in Fresno/Clovis Area

Promoting alternative forms of transportation is a major focus area in Transportation Planning. Information on pedestrians' and cyclists' exposure to traffic-related air pollutants during commute and utilization of parks and recreational areas is very limited in Fresno/Clovis area. This research will provide valuable insights and findings to plan transportation facilities better and promote more active transportation. To continue and expand the StarTraq 2020 project that characterized the roadside traffic-related particle pollution in Fresno/Clovis neighborhoods, promoting alternative forms of transportation by examining air pollution data collected near roadways and on trails as related to the active transportation modes of walking and bicycling. We will monitor the particulate matters from the different bike paths in the park and recreational areas. In addition, the particulate matters 'on-road (out-vehicle)' and 'in-vehicle will be monitored to compare and contrast the air quality inside and outside the vehicle. While air-pollution data is being gathered, GoPro cameras will record the surrounding scene information with GPS trajectory. To model the data's spatial and temporal characteristics, we will first perform exploratory data analysis by producing descriptive statistics and graphical summaries to understand these characteristics from the acquired data. We will then analyze the spatial and temporal variations using the appropriate data mining techniques such as clustering, classification, and regression.

Impacts/Benefits of Implementation: 

This research attempts to broaden the scope of the roadside, on-road, and in-vehicle air quality data from particle pollutants. The results will provide the baseline exposure levels for public health concerns of different transportation modes. In addition, the information on pedestrians' and cyclists' exposure to traffic-related air pollutants during commute and utilization of parks and recreational areas will be precious to promote the active transportation mode while developing strategies for reducing the risks associated with the mode of transportation via urban planning and policy development.
