Much of the developing world is experiencing rapid economic growth. Motor vehicle fleets in many megacities are doubling every seven years, creating a huge infrastructure backlog, escalating air quality problems, and imposing constraints on economic development. Besides rapid growth, the very...

One-half mile has become the accepted distance for gauging a transit station’s catchment area in the U.S. It is the de facto standard for planning TODs (transit oriented developments) in America. Planners and researchers use transit catchment areas not only to make predictions about...

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...

A central tenet of urban economics is that households, businesses, and industries compete for urban sites that enjoy accessibility advantages – whether to jobs, labor markets, raw materials, or distributions centers. Transportation investments trigger economic growth by enhancing...

All smart growth initiatives involve some degree of mixed land uses. Which mixed-use strategies – e.g., jobs-housing balance, adding retail to residential districts -- offer the greatest traffic-reducing benefits? This paper addresses this question by examining the degree to which job...

Shifts in job accessibility reflect, in part, the degree to which land use and transportation decisions are helping to economize on commuting and promote social equality objectives. This paper argues for the aggressive use of accessibility indicators as part of the long-range transportation...

A new relationship between elevated freeways and central-city neighborhoods seems to be forming. Despite worsening traffic congestion, a number of American cities have or are in the midst of demolishing elevated structures in favor of at-grade boulevards and arterials with far less traffic...

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...

Suburbia largely remains hostile territory for public transit in America and, indeed, much of the developed world. Transit’s market share of every type of trip is steadily eroding outside of central cities virtually the world over. With trip origins and destinations spread all over the...
