Abstract
ABSTRACT Cities and metropolitan regions face several challenges including urban sprawl, auto dependence and congestion, and related environmental and human health effects. Examining the spatial characteristics of daily household activity‐travel behavior holds important implications for understanding and addressing urban transportation issues. Research of this sort can inform development of urban land use policy that encourages the use of local opportunities, potentially leading to reduced motorized travel. This article examines the potential household activity‐travel response to a planned metropolitan polycentric hierarchy of activity centers. Behavioral observations have been drawn from an activity‐travel survey conducted in the Portland, Oregon, metropolitan area during the mid‐1990s. Evidence presented from exploratory analysis indicates an urban/suburban differential, with less daily travel and smaller activity spaces for urban households. Investigation of the travel reduction potential of the proposed land‐use strategy suggests that location effects could be offset by adjustments to household sociodemographic and mobility characteristics.
