Every year, Americans drivers spend hundreds of billions of dollars on highway transportation. They pay for vehicles, maintenance, repair, fuel, lubricants, tires, parts, insurance, parking, tolls, registration, fees, and other items. These expenditures buy Americans considerable personal...

A structural model is used to explain activity interactions between heads of households and, in so doing, to explain household demand for travel. The model attempts to capture links between activity participation and associated derived travel, links between activities performed by male and...

The January 17, 1994 Northridge Earthquake damaged four major freeways in the Los Angeles area, creating the prospect of gridlock in the nation's prototypical automobile city. This paper examines the effect of the transportation damage on business activity. Using survey responses from 559 firms...

Using micro data from the US Census, this paper tests the importance of the spatial isolation of minority and poverty households for youth employment in the largest US metropolitan areas. We first estimate a model relating youth employment probabilities to individual and family characteristics,...

The accurate prediction of rutting development is an essential element for the efficient management of pavement systems. In addition, progression models of highway pavement rutting can be used to study the effects of different loading levels, and thus in allocating cost responsibilities to...

The major goal of travel behavior research is to understand and model the processes by which people make decisions regarding activities and travel. These decisions, including whether, when, where, and with whom to participate in particular activities, and the choice of mode and route, are...

Travel demand models focus on explaining how much individuals actually travel but offer no insight into how much individuals think they travel. The authors propose that the latter is an important determinant of traveler behavior, and that actual mobility is refracted through a variety of filters...

In this article, we describe the development of atransit trip planner(TTP) for mobile devicescalled Transitr, and evaluate its performance. The system predicts the shortest paths betweenany two points in the transit network using real-time information provided by a third party busarrival...

The City of Los Angeles and Caltrans would like a simulation testbed for testing alternate traffic management strategies in the Santa Monica corridor. This study assesses the data available for such a simulation and describes data needs, potential sources, and data preparation required. It...

This paper presents the results of a qualitative survey of commercial owners, managers, and occupants in the City of Berkeley who have invested in on-site bicycle facilities such as secure parking, showers, changing rooms, and clothing lockers, what we are calling “bicycle-oriented...
