Employment and the journey to work have long been a focus of transportation study. Although today, the work trip accounts for a much smaller share of total trips than it did a few decades ago, there are several reasons why this subject deserves our continued attention.

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...

This paper examines the role of car access (including but not limited to car ownership) in facilitating employment among recipients under the current welfare-to-work law. In 1996, Congress enacted the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA), which dramatically...

Cars account for half the oil consumed in the U.S., about half the urban pollution and one fourth the greenhouse gases. They take a similar toll of resources in other industrial nations and in the cities of the developing world. As vehicle use continues to increase in the coming decade, the U.S....

This paper presents a reliability-based optimization model of inspection, maintenance, and replacement for a system of several highway bridges. The objective in the formulation is to minimize the total expected social cost, including the expected cost of failure. The frequency of inspections is...

This dissertation research proposes the development and evaluation of a new concept for high coverage point-to-point transit systems (HCPPT). Overall, three major contributions can be identified as the core of this research: the proposed scheme design, the development of sophisticated routing...

Managing the launch of new technological trajectories is a complex task, especially in the case of High-Speed Ground Transportation (HSGT) Systems. For instance, Maglev systems are now developed since 40 years, and none of these technologies has been implemented until the first Transrapid...

This literature review is the culmination of the first phase of a research study directed at reviewing, analyzing, and quantifying the impacts of transportation corridors’ design features on user behavior, safety, community and economic vitality, environmental quality, and public health....

Freeway “deconstruction†marks an abrupt shift in urban policy. Priorities are shifting away from designing cities to enhance mobility toward promoting economic and environmental sustainability, livability, and social equity. This paper investigates the neighborhood, traffic, and...

Just as the Eiffel Tower is the symbol of Paris, and the Statue of Liberty is the symbol of New York, it can be said that the freeway is an internationally recognized symbol of California. The California transportation system was not too long ago the envy of the world, yet there is today a...
