Book excerpt: The first practical guide to infrastructure security using Intelligent Transportation Systems (ITS) Intelligent Transportation Systems, or ITS, integrates different computing, control, and communication technologies to help monitor and manage traffic management that helps reduce congestion while saving lives, time, and money. While mobility and safety are the primary objectives of any good transportation system, security has also become an equally important consideration in their design and operation. This book provides a comprehensive treatment of techniques to leverage ITS in support of security and safety for surface transportation infrastructure. Through the book's multidisciplinary approach, readers gain a comprehensive introduction to the diverse aspects of transportation infrastructure security as well as how ITS can reduce risks and be protected from threats with such topics as computer systems, risk analysis, and multi-modal transportation systems. This book, which will serve as a textbook and guide, provides: Current ITS approaches to security issues such as freight security, disaster and evacuation response, HAZMAT incidents, rail security, and ITS Wide Area Alerts Guidance on the development of a regional transportation security plan Securing ITS itself and privacy issues involved in any collection and use of personally identifiable tracking data Exercises, question-and-answer sections, and other helpful review tools for the reader Filling a gap in the practical application of security, Transportation Infrastructure Security Utilizing Intelligent Transportation Systems offers both students and transportation professionals valuable insights into the new security challenges encountered and how to manage these challenges with the use of computerized transportation systems.
