Travel demand emerges from individual decisions. These decisions, depending on individual objectives, preferences, experiences and spatial knowledge about travel, are both heterogeneous and evolutionary. Research emerging from fields such as road pricing and ATIS requires travel demand models...

Although many individual route choice models have been proposed to incorporate travel time variability as a decision factor, they are typically still deterministic in the sense that the optimal strategy requires choosing one particular route that maximizes utility. In contrast, this study...

This study investigates the usage of road networks both within and outside of home jurisdictions (city (or town) and county of residence) by analyzing GPS data collected in the Minneapolis - Saint Paul metropolitan area, which tracked volunteers’ travel behavior to determine which roads...

The role of contacts on travel behavior has been getting increasing attention. This paper reports on data collected on individualÕs social meetings and the choice of in-home/out-of-home meeting locations as well as the distance travelled and duration of out-home-meetings and its relationship to...

This study estimates Value of Time differences between people who arrived at their destination as planned and those that were delayed. The analysis is based on the I-394 MnPASS High Occupancy/Toll (HOT) lane project recently implemented in the Minneapolis/St. Paul region. Using a Stated...

This paper examines the growth of a network based on the present conditions of the network, traffic demand, other demographic characteristics, project costs, and a budget constraint. The effects of expanding a link on its upstream and downstream neighbors, as well as on parallel links are also...

The present research develops an agent-based model to treat the organization, growth, and contraction of network elements. The components model travel demand, revenue, cost, and investment. Revenue earned by links in excess of maintenance costs is invested on the link to until all revenue is...

This study explores the economic mechanisms behind the decline of a surface transportation network, based on the assumption that the decline phase is a spontaneous process driven by decentralized decisions of individual travelers and privatized links. A simulation model is developed with a...

In Fall 2000, more than 430 ramp meters in the Twin Cities metropolitan area were shut down in order to evaluate the effectiveness of the metering system. This shutdown disturbed normal traffic patterns and thus traffic equilibrium. The purpose of our research is to examine how long it takes to...

This research examines road pricing on a network of autonomous highway links. By autonomous it is meant that the links are competitive and independent, with the objective of maximizing their own profits without regard for either social welfare or the profits of other links. The principal goal of...
