Disaggregate studies of the impacts of telecommunications applications (e.g. telecommuting) on travel have generally found a net substitution effect. However, such studies have all been short-term and small-scale, and there is reason to believe that when more indirect and longer-term effects are...

The focus of this research is the commercial strip of the American inner city which, due to disinvestment, high crime rates, arbitrary and haphazard development, and poor connections to surrounding residential neighbourhoods, has become a problematic environment. Physical retrofit and economic...

In this paper we combine theoretical and empirical research on cognitive mapping with our own initial research on the topic to suggest how cognitive mapping might be employed to help us better understand and predict travel behavior, emphasizing how spatial cognition shapes access to opportunity....

Freeway “deconstruction†marks an abrupt shift in urban policy. Priorities are shifting away from designing cities to enhance mobility toward promoting livability. This paper investigates the neighborhood, traffic, and housing price impacts of replacing elevated freeways with surface...

The need for more comprehensive traveler welfare measures is highlighted by the U.S. Intermodal Surface Transportation Efficiency Act (1991) requirement that transportation projects and plans be evaluated for economic efficiency. However, to date, there has been a discrepancy between this...

Although land use planning and urban design are increasingly touted as powerful tools for influencing transportation behavior, only modest empirical evidence for this relationship exists. Here, the results from a two-day activity diary are combined with innovative GIS-based measures of urban...

Urban population density may influence transportation demand, e.g., as expressed through average daily vehicle-kilometers traveled in private motor vehicles per capita. In turn, changes in transportation demand influence total passenger vehicle emissions to which populations are exposed....

Intelligent transportation technologies (ITT’s) are being promoted as a means of reducing congestion delay, improving transportation safety, and also as a means of making vehicle travel "...more energy efficient and environmentally benign (USDOT, 1990)." In theory, IVHS technologies will...

Over the past forty years, El Sobrante, California, has changed from a small rural center in the midst of grazing land to a mostly-developed residential suburb. Both San Pablo Dam Road (the main roadway through El Sobrante) and the commercial district stretching along that roadway also have...

In many urban areas, noise is a serious problem. Noise disturbs sleep, disrupts activities, hinders work, impedes learning, and causes stress (Linster, 1990). Indeed, surveys often find that noise is the most common disturbance in the home (Organization for Economic Cooperation and Development...
