This working paper is a preliminary review of the state of the art in the study of the economics of traffic information. The focus is on the different methods used to model the decision process of drivers in a traffic system, and on the effect of traffic information on this process. In addition,...

It seems that transportation planners everywhere are looking for ways of reducing vehicle miles of travel (VMT) by automobile, even as citizens seem determined to drive more. The trend may be especially evident here in California where everyone seems to believe that use of cars is excessive,...

There is little doubt that a high-speed rail line could be built in the California corridor, connecting San Francisco and Los Angeles. To be sure some major obstacles must be reckoned with. It will have to cross the Tehachapi Mountains directly, if it's to keep travel time under control. This...

This research, sponsored by the Port Authority of New York and New Jersey, involved the development and application of a model of International Gateway Competition, to be used for purposes of airport demand forecasting and airline strategy assessment. The model, named ALIGATER (AirLine...

One of the challenges facing intermodal integration is that the planning framework needed for it lacks appropriate measures of level of service that cut across the modes involved and the connections between them. In this study we develop a framework and a set of metrics of level of service in a...

The State of California will face an important transportation investment decision during the coming decade. With ever increasing demands for intercity travel in the entire corridor between Sacramento and San Diego, the State will need to consider the options available for expanding the capacity...

Changes in the U.S. domestic airline route system have increased competition between international gateways. To assist in understanding this phenomenon, a system of models that predicts airline passenger flows resulting from different airline gateway hubbing strategies has been developed. The...

The Intermodal Surface Transportation Efficiency Act of 1991, calls for closer coordination of intermodal transportation as a method to solve many of today’s transportation problems. The passage of this Act has prompted many engineers and planners to re-assess the potential benefits of...
