Download Free Traveler Information Systems Book in PDF and EPUB Free Download. You can read online Traveler Information Systems and write the review.

Advanced Traveler Information Systems explores the whole traveler information supply chain, from needs analysis and data collection to information processing and dissemination. It provides you with the first comprehensive, balanced view of both the public and private sides of the traveler information business. You get an indepth review of the public sector information domain with extensive case studies, practical advice and guidance based on real world experiences. This book directly addresses the need to provide sufficient information to support travel behavoir changes and make the best use of limited public funds. It offers you a sound perspective on the key issue of fair valuation of traveler information related data, and presents some possible new approaches for you to consider. If you are seeking the latest information on transportation efficiency and effectiveness, or looking for ways to exploit related new opportunities in the field, this book is must reading for you.
This synthesis reports on the state of the practice in real-time traveler information systems. Emphasis is placed on the needs and expectations of travelers, the current status of a variety of traveler information systems in the United States, available and emerging data sources, and business models for sustaining traveler information. This synthesis will benefit state DOT transportation managers and others that provide or seek to provide affordable, accurate, timely, and effective information in a format that travelers can use.
Provides a useful summary of the state of the practice in the area of improved transit traveler information. The result identifies transit traveler information needs, assesses the state of the art in providing transit traveler information, provides examples of customer information systems from both inside the transit industry and related industries, discusses transit traveler information as part of larger community information systems, and offers new directions for the transit industry in providing traveler information.

The Intelligent Transportation System (ITS) Program is a cooperative effort by government, private industry, and academia to apply advanced technology to the task of resolving the problems of surface transportation. The objective is to improve travel efficiency and mobility, enhance safety, conserve energy, provide economic benefits, and protect the environment. The current demand for mobility has exceeded the available capacity of the roadway system. Because the highway system cannot be expanded, except in minor ways, the available capacity must be used more efficiently to handle the increased demand. ITS applies advanced information processing, communication, sensing, and computer control technologies to the problems of surface transportation. Considerable research and development efforts will be required to produce these new technologies and to convert technologies developed in the defense and space programs to solve surface transportation problems. ITS has been subdivided into six interlocking technology areas. This book addresses human factors concerns for four of these areas: * Advanced Traveler Information Systems are a variety of systems that provide real time, in-vehicle information to drivers regarding navigation and route guidance, motorist services, roadway signing, and hazard warnings. * Advanced Vehicle Control Systems refer to systems that aid drivers in controlling their vehicle particularly in emergency situations and ultimately taking over some or all of the driving tasks. * Commercial Vehicle Operations address the application of ITS technologies to the special needs of commercial roadway vehicles including automated vehicle identification, location, weigh-in-motion, clearance sensing, and record keeping. * Advanced Traffic Management Systems monitor, control and manage traffic on streets and highways to reduce congestion using vehicle route diversion, automated signal timing, changeable message signs, and priority control systems. Two technical areas are not specifically addressed in individual chapters, but many aspects of them are covered in associated chapters: * Advanced Rural Transportation Systems include systems that apply ITS technologies to the special needs of rural systems and include emergency notification and response, vehicle location, and traveler information. * Advanced Public Transportation Systems enhance the effectiveness, attractiveness and economics of public transportation and include fleet management, automated fare collection, and real-time information systems.
This handbook, which was developed in recognition of the need for the compilation and dissemination of information on advanced traffic control systems, presents the basic principles for the planning, design, and implementation of such systems for urban streets and freeways. The presentation concept and organization of this handbook is developed from the viewpoint of systems engineering. Traffic control studies are described, and traffic control and surveillance concepts are reviewed. Hardware components are outlined, and computer concepts, and communication concepts are stated. Local and central controllers are described, as well as display, television and driver information systems. Available systems technology and candidate system definition, evaluation and implementation are also covered. The management of traffic control systems is discussed.
