The detection of impending collisions and the subsequent choice and regulation of maneuvers to deal with them are general problems of locomotor control that arise in many situations, both human and non-human. When an object moves towards an observer, the size of the image that it projects onto...

Considerations of the impacts of electronic technologies on transportation usually focus on substitution of communications for travel, especially telecommuting. This topic is reviewed briefly, followed by consideration of electronic technology-induced changes in the structure of firms, work by...

This dissertation summarizes research investigating the design of real-time traffic maps. As traffic congestion continues to burden our largest cities, and as the Internet continues to grow at a rapid pace, real-time traffic maps have the potential to be among the world’s most popular...

Mexico City is a suburban metropolis, yet most of its suburbs would be unfamiliar to urbanists accustomed to thinking about US metropolitan regions. Mexico City’s suburbs are densely populated—not thinly settled—and its residents rely primarily on informal transit...

Experiments using smartphones to influence behavior have been growing rapidly in many fields, especially in health and fitness research, and studies on eco-feedback technologies. In these studies, users are first tracked to understand their baseline behaviors, then measured continuously while...

After over a decade of debate, construction of the San Francisco-Oakland Bay Bridge’s eastern span finally began in 2002 at a current approximate cost estimate of $6 billion. The intense and controversial debate ranged from whether the bridge should be seismically retrofitted or replaced,...
