The vehicle miles of travel for each vehicle in multi-vehicle households is modeled as a function of household characteristics, vehicle characteristics, and the matches of vehicle to driver in the satisfaction of travel desires. A structural equations model is developed in which principal driver...

One of the major foci in transport research is the identification of the temporal-spatial decision making structure embedded in activity scheduling and its linkage to actual activity/travel execution. The latter part of the research in question has not been explored explicitly in real life...

Broken sidewalks have become an important legal issue since 2002 when the United States Court of Appeals for the NinthCircuit ruled that the Americans with Disabilities ActADAapplies to sidewalks. As one way to comply with the ADA, cities can requireproperty owners to repair any broken sidewalk...

Researchers have questioned whether the ability to telecommute is encouraging workers to relocate to more desirable residences farther from work, and in doing so, exacerbate sprawl and increase their net vehicle-miles traveled. The research presented here directly asks, is telecommuting a...

Greenhouse gases (GHG), the gases that cause climate change, are a major global concern. In the transportation sector, GHG reduction initiatives focus on passenger travel over goods movement, despite increasing freight demand and related emissions. California, with its recent GHG reduction...

Despite the size and growth of the immigrant population in the U.S., only a handful of scholars have studied the travel behavior of immigrants and its impact on our nation’s roads, highways, and transit systems. Yet immigration has affected and will continue to affect our transportation...

Communities are traditionally built with one transportation mode and user in mind—the adult automobile driver. Recently, however, there has been an international focus on the trip to school as an opportunity to enhance children’s independent active travel. Several factors must be...

Escalating concerns about air quality in Southern California have led authorities of the Ports of Los Angeles and Long Beach, also known as the San Pedro Bay Ports (SPBP), to consider and adopt a number of emission mitigation measures. One possibility is to shift to trains some of the containers...

Changes in the U.S. domestic airline route system have increased competition between international gateways. To assist in understanding this phenomenon, a system of models that predicts airline passenger flows resulting from different airline gateway hubbing strategies has been developed. The...

This paper analyzes a model of early morning traffic congestion, that is a special case of the model considered in Newell (1988). A fixed number of identical vehicles travel along a single-lane road of constant width from a common origin to a common destination, with LWR flow congestion and...
