Evaluating unintended outcomes of regional smart-growth strategies: Environmental justice and public health concerns

摘要: Abstract Many urban areas are perusing infill, transit oriented, and other “smart-growth” strategies to address a range of important regional goals. Denser more mixed use development may increase sustainability improve public health by reducing vehicle travel increasing the share trips made transit, walking bicycling. Fewer results in fewer greenhouse gas toxic emissions, bicycle increases physical activity. Prior research has largely focused on modeling estimating potential size these smart-growth strategy benefits. A overlooked area is for unexpected costs environmental justice concerns that result from density. We evaluate land-use transportation planning scenarios developed year 2040 metropolitan organization with newly air quality framework. Our find set plans designed MPO promote estimated less emissions than typical higher population exposure emissions. The also greater income-exposure inequality, raising concerns. conclude spatially detailed scale analysis can inform creation smarter plans.
