In this paper a simultaneous modeling system for dichotomous endogenous variables is developed and applied empirically to longitudinal travel demand data of modal choice. The reported research is motivated by three factors. First, the analysis of discrete data has become standard practice among...

In this paper a model is developed and estimated empirically of the allocation of time to out-of-home activities and travel. The model has three important characteristics. First, the allocation of time to out of home activities by individuals is the key concept in the research reported here....

A dynamic (panel data) structural equations model is developed that links four dependent travel behavior variables at two points in time, one year apart. The four dependent variables are: car ownership, travel time per week by car, travel time by public transit, and travel time by nonmotorized...

This research has two objectives. The first objective is to explore the use of the modeling tool called "latent structural equations" (structural equations with latent variables) in the general field of travel behavior analysis and the more specific field of dynamic analysis of travel behavior....

Local area freight networks (LANs) are used to collect and distribute freight within metropolitan regions. Focusing on common carriers, this paper classifies LAN topologies, then shows how the optimal topology depends on demand characteristics. Continuous space approximations are used to analyze...

The growth of the Internet has rekindled interest in the relationship between communications and travel. New communication technologies have expanded the range, the type, and the number of transactions that can take place without travel. A number of promotions capture the new tradeoffs between...

If truck drivers could use internet-enabled wireless devices to access traveler information, what type of information would they most want to have? The answer almost surely varies according to the type of trucking operation, location, and many other factors. We analyzed preferences for traveler...

This paper puts forth some ideas for extending travel behavior modeling to account for interactions between travel and telecommunications. Information technology (IT, sometimes referred to as communications and information technology, or CIT) is burgeoning, providing unlimited business...

The growth of the internet has rekindled in the relationship between communication and travel. New communication technologies have expanded the range, the type, and the number of transactions that can take place without travel. A number of promotions capture the new tradeoffs between...

A three-year experiment is underway in San Diego County, California that allows solo drivers to pay a fee to use "Express Lanes" i.e. carpool lanes to avoid an eighty-mile highly congested stretch of freeway. These lanes are also commonly referred to as High Occupancy Toll (HOT) Lanes. The...
