Previous studies of the potential market for battery electric vehicles (BEVs) have reached contradictory conclusions. What they share are untested or implausible assumptions about consumer response to new transportation technology. We frame the BEV purchase decision in terms of a household's...

Traffic exposure assessments could misclassify the extent and locations of exposure if traditional recall surveys and self-reported travel diaries do not record all participant activities. The Harbor Communities Time Location Study (HCTLS) examines the nature, extent and implications of...

Formulation and specification of activity analysis models require better understanding of time allocation behavior that goes beyond the more recent within household analyses to understand selfish and altruistic behavior and how this relates to travel behavior. Using data from 1471 persons in a...

The sprawling patterns of land development common to metropolitan areas of the US have been blamed for high levels of automobile travel, and thus for air quality problems. In response, smart growth programs— designed to counter sprawl—have gained popularity in the US. Studies show...

Despite the recent economic downturn, electronic commerce (e-commerce) continues to show strong growth. According to the U.S. Census Bureau, e-commerce retail sales for 2002 reached at $45.6 billion, an increase of 26.9% from 2001, while total retail sales increased 3.1% during the same period....

In this project we develop a new travel demand forecasting system that integrates demographic microsimulation with urban simulation and travel demand model systems. Our research objective is to identify the barriers in integrating complex simulation models and eliminate them by offering a...

In this paper, using data from 366 households we study human interaction within and outside the household. In the analysis altruism and companionship between men and women are explored using path analysis to identify gender-roles and mutual influences. Men and women have very different templates...

Structural equation modeling (SEM) is an extremely flexible linear-in-parameters multivariate statistical modeling technique. It has been used in modeling travel behavior and values since about 1980, and its use is rapidly accelerating, partially due to the availability of improved software. The...

This article reviews empirical studies of how employer-paid parking affects employees' travel choices. A strong effect is found: parking subsidies greatly increase solo driving.When employers reduce or remove parking subsidies, a significant number of solo drivers shift to carpools and/or...

Driven by problems of traffic congestion, U.S. policy toward urban highways has lurched over several decades from highway building to high-occupancy-vehicle lanes to travel demand management. Yet congestion has worsened, and there is scant evidence that these policies have had any appreciable...
