Abstract: This study investigates the potential health impacts of implementing a hypothetical Congestion Charging Scheme (CCS) in Los Angeles (LA), a city facing significant traffic-related air pollution. Traffic emissions are a major source of pollutants like particulate matter (PM10), carbon monoxide (CO), and nitrogen dioxide (NO2), which have been linked to respiratory and cardiovascular diseases. Utilizing intervention-based epidemiological study designs, the research estimates the effects of a proposed 25% traffic reduction in downtown LA. Simulated results indicate a substantial decrease in NO2 and PM10 levels, with predicted increases of 1,263.58 years of life gained (YLG) in the greater LA area over a decade. The discussion highlights the potential of CCS to not only reduce pollution but also address socio-economic disparities in health outcomes. This model could serve as a blueprint for other urban areas considering similar policy interventions.
