...In slightly more than 300 pages, this text comprehensively and concisely examines the technologies involved in current vehicle location and navigation systems. Ideally suited for the system engineer, manager, or undergraduate who is new to this technology, this book would also serve as an excellent starting point for professionals involved in one specific area of this field and wishing to become familiar with other aspects of ITS. ...The author is clearly familiar with, and has thoroughly researched, the various topic areas covered in this text, as evidenced in his discussion of the technologies, their vendors, applicable standards, and system merits. The publications primary strength lies in the detailed discussion of the separate modules. I recommend this book to people who not only want to understand this field but must do so in a hurry.

--GPS World, April 1999

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 doesnt the output of your GPS receiver match your digital map?
When shouldn’t your vehicle be redirected to a less congested road?
Why doesnt 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.
