Abstract
Sweta Byahut will present her research design and discuss the outcomes of her
recently completed dissertation research. In her research she explores the
land use – transportation – environmental nexus in Hamilton County, OH
that includes the city of Cincinnati. Carbon dioxide (CO2) emissions from
household travel are a major contributor to climate change, generating up to
65% of total transportation CO2 emissions in the US. Urban and regional
planners have long been exploring the feasibility of mixed use as a potential
climate mitigation tool, with the belief that there is a significant link
between different aspects of the built environment and the vehicle miles
traveled (VMT). However, there are concerns that the link between built form
and land use is not strong enough due to lack of enough convincing studies
and often conflicting evidence. In her research she analyzes the impact of
land use diversity and other land use characteristics on household travel.
She developed an improved entropy-based measure of land use diversity, and
measures for building density, street and intersection density, distance to transit, and regional accessibility using advanced GIS tools with parcel
level land use data, and estimated household travel from the GPS-based
Greater Cincinnati Household Travel Survey 2009-10. Her research informs
policy makers on the feasibility of using land use diversity and other land
use characteristics for reducing household travel related emissions. The
audience will develop a better understanding of the relationship between
different land use characteristics and household travel at a regional scale,
the application of advanced GIS tools in land use metrics, and the potential
for travel demand management through compact and mixed use development.
