This is the first book to provide, in a single source, the detailed interdisciplinary information needed to understand, design and implement advanced Intelligent Transportation Systems (ITS, formerly IVHS). It presents state-of-the-art principles and practices that you can apply to a wide range of vehicle location and navigation systems - placing special emphasis on the vehicle side of the system - and synthesizes information scattered among many different engineering fields. Based on several years of hands-on research, the book is divided into two parts: Basic Modules, or building blocks, and Systems, or integrated modules. Fundamental principles as well as newly developed technologies, along with many problem-solving examples, help you save time and improve performance. Turn to this well-organized, practical book for answers to such real-life questions as: Why doesn't the output of your GPS receiver match your digital map?; When shouldn 't your vehicle be redirected to a less congested road?; Why doesn't your navigation system work as expected after going through the automatic car wash? The newly developed technologies you find here include a fuzzy-logic-based algorithm, the field-emitter display (FED), a recently invented software technology for 3-D map display, and a seldom discussed integrated Dispatch Enhanced Network (iDEN). Accessible even to non-engineering specialists, this informative book contains useful summary tables and current references, including Internet addresses for ITS-related pages.
