PREFACE NTELLIGENT TRANSPORTATION SYSTEMS :
It has been more than 10 years since we sat down to write the first edition, Intelligent Transportation Systems: New Principles and Architectures with great excitement, back in 1999. Since then a number of significant and encouraging improvements have been incorporated into transportation systems, worldwide, while a number of areas are continuing to witness rapid deterioration. One undeniable fact stands clear. The promise of intelligent transportation systems (ITS) is greater than ever before, and it is yet to be fulfilled. The congestion, uncertainty, and the lack of a clear direction for the future of transportation continue to persist.
Key impediments include the absence of a critical mass of ITS engineer-scientists with the right background and training as well as the lack of adequate research and development thrusts, worldwide. This book is intended to serve as a reminder, within the United States, of not only
the development of educational programs focused on ITS directed toward the future transportation workforce but also the professional capacity building initiatives underlying the current transportation workforce. Both of these may be traced to a formidable challenge that we have already begun to encounter in the twenty-first century in virtually every field—the need for a completely new mindset that is intimately connected to interdisciplinary, transdisciplinary, or cross-disciplinary research and education.
The notion of transportation refers to the movement of people and goods across nontrivial geographical distances, and its history is as old as our civilization. Its scope is enormous, ranging from people walking on the earth’s surface to carts and chariots driven by animals, automobiles, trains, airplanes, and ships. Despite the great diversity in the modes of transportation, a unique characteristic emerges—the constant effort that has continued throughout history to improve its efficiency by providing information and guidance to the constituent entities. In the past, information was carried by people and by material in the form of messages and, as a result, the rate of propagation of information was closely related to that of the mode of the transportation. With the emergence of electromagnetic communication, in the last century, the discipline of transportation experienced a remarkable transformation.
A central control would gather information about every entity within a specific transportation system and provide guidance and information to them as necessary. When systems were isolated, small, and few in number, decentralized control was the norm. Ironically, as systems grew larger due to consolidation, etc., control became centralized.
