PhD Dissertation Defense: NITC Fellow Kristina Currans
Advisor: Dr. Kelly J. Clifton
Since its first edition in 1976, the Institute of Transportation Engineers (ITE) Trip Generation Handbook has become the predominant method for estimating the transportation impacts of land use, despite the lack of sensitivity to changes in the urban environments. As a result, local governments continue to be hampered by the urban application of the Handbook, overestimating (and overcharging for) automobile facilities, creating additional barriers to achieving multimodal or sustainable comprehensive plans. This dissertation explores the spatial, social, and temporal contexts of ITE’s Handbook, quantifying variations in vehicle trip generation estimates where possible. The findings from a case study application—building upon several previous studies as well as the author’s original analyses—suggest the compounded bias of these data substantially overestimate retail automobile demand, even in the suburban areas for which these data are meant to represent. Implications and recommendations for practice will be discussed.
Kristina Currans pursues research focusing on the relationship between travel behavior and land use. Her work is motivated by her personal interest in improving the ways in which we plan for development, ultimately giving communities more choices in how they live and how they get around.
