Evaluating health outcomes from vehicle emissions exposure in the long range regional transportation planning process

摘要: Abstract The air quality impacts of a metropolitan region's long range transportation plans are generally evaluated by estimating the change in vehicle emission inventory. A overall quantity emissions region is associated with lower concentrations related pollutants and therefore reduction public health risks from exposure to emissions. major limitation this common approach that aggregate inventories provide no information about localized impacts. While some areas experience improvements, can become worse others. Such analyses ill suited for addressing contemporary planning questions such as identifying hotspots, quantifying risks, evaluating environmental justice concerns. In paper we describe computationally efficient analysis framework regional plan spatially detailed estimates exposures outcomes. We then apply our case study fine particulate matter Atlanta, Georgia area changes expected occur through year 2040 under plan. find decline current levels 2020 but begin slowly increase 2040. also low income minority populations have greatest confirming concerns been noted other regions.
