Title:

Exploring the Influence of Urban Form on Travel and Energy Consumption: a Tour-based or a Trip-based Analysis?

Abstract:

This research has contributed to the current knowledge of the relationship of urban from to travel by gaining additional insights into the linkages of different aspects of the built environment with travel behavior, and energy consumption using Structural Equation Modeling (SEM). Several urban form measurements were gathered from multiple external sources and utilized for both trip/tour origins and destinations. This research also contributed to the current knowledge by analyzing both trips and tours to test whether the tour analysis generates improved results over trip analysis. In addition, tour-based samples were stratified by purpose, mode, and the combination of mode and purpose to investigate the detailed travel behavior differences. The research findings are many: (1) Tour-based analyses have better model fit than trip-based analysis; (2) Different purposes and modes of travel exhibit different types of behavior and should be analyzed separately; (3) Urban form has direct effects on travel distance; (4) Urban form at the destination ends have more influence than on the origin ends; (5) Urban form has indirect effects on travel distance and energy consumption through affecting driving patterns, mode choice, vehicle type and tour complexity; (6) People tend to drive when they have complicated travel patterns; (7) The effects of intermediate variables (driving patterns, tour complexity, mode choice, and vehicle type) are stronger than the direct effects. No single transportation technology or land use policy action can offer a complete checklist for achieving deep reductions of travel and energy consumption while preserving mobility of driving.
