Brian Cole, DrPH | Health and Equity Implications of Gas Taxes & Mileage Based User Fees to Address California’s Transportation ShortfallThe United States and other developed, as well as developing countries are facing increasingly lethal and costly epidemics of acute and chronic diseases related to land use and built environment decisions. While hazards presented by air and water pollution are well recognized for acute, infectious, and toxicological illnesses, there is increasing recognition of hazards presented by building and community designs that fail to recognize human health. Land use and built environment decisions impact every age and social group, some disproportionately, with impacts ranging from the very acute (motor vehicle trauma) to the long term (obesity, cancer, heart disease). Such decisions should be based in solid science that considers not only health, but also economic, financial, insurance, housing, and other factors.

COEH maintains a strong research and education program on the health impacts of land use and the built environment. COEH Director Michael Jerrett is an expert in this field with projects on built environment topics related to active transport systems, greenspace exposure, and smart growth communities effects on physical activity, to name a few. COEH faculty member Yifang Zhu conducts natural experiments on how built environment changes affect air quality, such as the temporary closure of the 405-freeway, complete streets improvements, and the open streets program CicLAvia.
