The rise of e-commerce has led to substantial changes in personal travel and activities. We systematically reviewed empirical studies on the relationship between online shopping behaviour. synthesised assessed evidence for four types effects various outcomes, including trip frequency, distance, chaining, mode choice, time use. In 42 articles reviewed, we found more that substitutes travel. Most...

I develop a structural model of urban travel to estimate long-run gasoline price elasticities. the demand for transportation services using dynamic discrete-choice with switching costs and it panel dataset public market-level data on automobile transit use in Chicago. Long-run own- (automobile) cross- (transit) elasticities are substantially more elastic than short-run Elasticity estimates from...

SUMMARY Formal evaluation procedures for new advanced traffic management systems are essential for documenting ITS benefits. Such procedures are also very important during the " turn-on " phase of a deployment so those government agencies managing the deployment have quantifiable measures to determine that a system is working as specified. Current ATMS evaluation procedures during deployment re...

The paper sums up the factors with passenger’s travel demand, passenger’s need of comfort and the wasted train capacity. On the basis of these factors, this paper provides a new idea to solve high-speed passengers train operation plan problem. First, all the possible train operation plans are listed, and then with the aid of intelligent algorithm those train operation plans which can not be sen...

This paper argues that transportation planning methodologies must be built on the central thesis of the activity-based approach to travel demand modeling, namely, that travel is a derived demand that reflects people’s desire and need to participate in activities. The paper discusses why this foundation for transportation planning methodologies is necessary to address contemporary planning and p...

Since the beginning of civilization, the viability and economic success of communities have been, to a major extent, determined by the efficiency of the transportation infrastructure. Travel demand models are used for this purpose. Mode choice behavior is a fundamental element of travel behavior. It is the demand for activities that produces the demand for travel. In other words the need or des...

Research on travel demand modeling has primarily focused on weekday activity-travel patterns. However, weekend activities and travel constitute a major component of individuals’ overall weekly activity-travel participation. This paper describes a modeling effort that focuses on discretionary-event weekend activity-travel demand. This study bridges the gap in the literature by modeling discretio...

A Utility-Theory-Consistent System-of-Demand-Equations Approach to Household Travel Choice by Kara Maria Kockelman Doctor of Philosophy in Civil and Environmental Engineering University of California, Berkeley Professor Mark Hansen, Chair Modeling personal travel behavior is complex, particularly when one tries to adhere closely to actual causal mechanisms while predicting human response to cha...
