The objective of this book is to suggest solutions to our 21st Century reional transportation problems. The author's proposals address a variety of regional transportation concepts, in case study format, regarding the current dilemma of how to implement improvements to the Tappan Zee Bridge. The Tappan Zee Bridge is a major transportation link to the New York City Metropolitan Regional Area as well as to the New England Regional Area. This delemma epitomizes transportation issues faced by other large regional metropolitan areas throughout the world. To successfully resolve the questions posed requires a systematic and coordinated approach for managing 21st Century traffic. The need for a comprehensive transportation plan was brought into focus by the destruction of the World Trade Center in New York City on September 11, 2001, which demonstrated the need for alternative transportation systems within the New York City Metropolitan Regional Area.
