Most policies to cut the transportation sector’s CO2 emissions focus on fuel-efficient vehicles, low-carbon fuels, and reductions in vehicle-miles traveled. One strategy that gets less attention but has high potential pay-off is Intelligent Transportation Systems (ITS). An example is...

Over the past several years, the private vehicle has become the predominant mode of travel to school while walking and bicycling rates have decreased. Some suggest that this change in travel behavior contributes to negative health outcomes in children, including increased rates of 1)...

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...

A trip generation model has been developed using a time-use perspective, in which trips are generated in conjunction with out-of-home activities, and time spent traveling is another component of overall time use. The model jointly forecasts three sets of endogenous variables- (1) activity...

Modern panel surveys frequently suffer from high and likely non-ignorable attrition, and transportation surveys suffer from poor travel time estimates. This paper examines new methods for adjusting forecasts and model estimates to account for these problems. The methods we describe are...

Land development and vehicle travel continue to outpace population growth. Efforts to manage this growth and the adverse impacts associated with it have been mostly ineffective. Promising technology solutions include telecommunications (telecommuting, electronic commerce, teleconferencing,...

Since 1923 motor fuel taxes have been the principal instrument by which revenues are raised for the construction and maintenance of the California highway system. Fuel taxes are distinguished from most other taxes because they have been conceived of as a “user fee†rather than as a...

The emergence of geographical theory was an inevitable product of the desire to systematize existing geographic knowledge and to use that systematized base to explore new areas of knowledge. Although the usefulness of theory and predictive models in geography is by now a matter of record, it was...

In Brazil, the recent explosion of informal transport activity is having profound effects on formal, regulated transport systems and is the source of great controversy in the urban passenger transportation arena. A variety of policies are being proposed to manage what has been an uncontrolled...

This dissertation examines why and how jurisdictions choose to finance theirroads. The systematic causes ofrevenue choice are explored qualitatively by examining the history of turn pikes. The question is approached analytically by employing game theory tomodel revenue choice on a long road. The...
