This publication presents information on how Intelligent Transportation Systems (ITS) can help us operate and manage the transportation system to its potential. Mainstreaming ITS will be needed to maintain the mobility and accessibility the public demands and to leverage transportation investments with ITS operations and management approaches. Further, incorporating ITS in the planning process can help ensure that investments work together toward the operation of an efficient, customer-friendly, economically sound, and environmentally sensitive transportation system. The guide is organized in three parts. Part One defines major categories of ITS applications and provides examples of each. It includes information on the estimated nationwide benefits of ITS implementation over the next 20 years, and discusses the measured benefits of ITS applications to date and how ITS helps local government agencies in areas other than transportation. Part Two shows the relationship between transportation problems, traditional solutions and ITS approaches to improved systems management and operations. It describes the major elements of the transportation planning process and the National ITS Architecture. The case for mainstreaming ITS is presented along with how ITS fits into statewide or regional visions for the future transportation system. Steps in the planning process and the role of ITS are discussed. Opportunities to incorporate ITS into corridor and sub-area analysis are described. Examples of ITS projects in place today are provided. Part Three discusses issues and challenges in implementing ITS. |
