Exploring Regional Reduction Pathways for Human Exposure to Fine Particulate Matter (PM_2.5) Using a Traffic Assignment Model.

ABSTRACT: An exposure-based traffic assignment (TA) model is used to quantify primary and secondary fine particulate matter (PM_2.5) exposure from on-road vehicle flow on the Chicago Metropolitan Area regional network. PM_2.5 exposure due to emissions from light-duty vehicles, heavy-duty trucks, public transportation, and electricity generation for electric vehicle charging and light-rail transportation is considered. The model uses travel demand data disaggregated by time-of-day period and vehicle user class to compare the exposure impacts of two TA optimization scenarios: a baseline user equilibrium with respect to travel time (UET) and a system optimal with respect to pollutant intake (SOI). Estimated baseline PM_2.5 exposure damages are $3.7B-$8.3B/year. The SOI use
