DOWNLOAD EBOOKThis monograph provides an extended overview of modelling and control approaches for freeway traffic systems, moving from the early methods to the most recent scientific results and field implementations. The concepts of green traffic systems and smart mobility are addressed in the book, since a modern freeway traffic management system should be designed to be sustainable. Future perspectives on freeway traffic control are also analysed and discussed with reference to the most recent technological advancements The most widespread modelling and control techniques for freeway traffic systems are treated with mathematical rigour, but also discussed with reference to their performance assessment and to the expected impact of their practical usage in real traffic systems. In order to make the book accessible to readers of different backgrounds, some fundamental aspects of traffic theory as well as some basic control concepts, useful for better understanding the addressed topics, are provided in the book. This monograph can be used as a textbook for courses on transport engineering, traffic management and control. It is also addressed to experts working in traffic monitoring and control areas and to researchers, technicians and practitioners of both transportation and control engineering. The authors’ systematic vision of traffic modelling and control methods developed over decades makes the book a valuable survey resource for freeway traffic managers, freeway stakeholders and transportation public authorities with professional interests in freeway traffic systems. Advances in Industrial Control reports and encourages the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.

DOWNLOAD EBOOKThe report reviews, synthesizes, and interprets the impacts and costs of urban traffic control system improvements. Four major categories of control system improvements are covered: coordination of traffic signals; optimization of traffic signal timing; advanced computer-based master control systems; and freeway traffic management systems. Project level impacts and areawide impacts are given for various types of traffic control projects and comprehensive combined programs. The current implementation status of the different types of traffic control improvements, institutional impediments, and cost effectiveness is discussed. Special treatment is given to the impacts of improved traffic control on energy consumption.

DOWNLOAD EBOOKIntelligent Freeway Transportation Systems: Functional Design focuses on the efficient use of resources in the design of ITS. It discusses the principles of top down design starting with objectives and requirements, and provides guidance for the development and evaluation of functional design alternatives according to cost effectiveness principles. It shows how transportation planning principles such as Wardrop’s Laws and traffic diversion principles relate to functional ITS device selections and equipment locations. Methodologies for translating objectives to functional device types are provided. Application factors to identify device deployment densities (e.g. number of detectors per mile) as a function of traffic conditions are provided, as are evaluation models for evaluating the benefits of design alternatives based on traffic conditions. Design guidance and benefits evaluation include the following functions: (1) Non-recurrent congestion – Improvement of incident clearance time, (2) Non recurrent congestion – Incident information to motorists, (3) Recurrent congestion – Information to motorists, (4) Ramp metering, (5) Motorist service patrols.

DOWNLOAD EBOOKThis handbook is an update of the 1983 edition and reflects the tremendous developments in computing and communications technology. It also reflects the importance of "Integrated" Transportation Management Systems and the development of the concept of Intelligent Transportation Systems (ITS). The handbook development began with a survey of current practice, including site visits and interviews, of ten Freeway Management Systems throughout the country. It was developed under the advice of a panel of freeway management practitioners. The 1997 edition is organized in modular fashion with each module addressing a particular aspect or technology of the freeway management task. The modules are stand-alone treatments of particular areas of freeway management but are cross-referenced to reflect their interdependence

DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKIntelligent Transportation Systems: Functional Design for Economical and Efficient Traffic Management provides practical guidance on the efficient use of resources in the design of ITS. The author explains how functional design alternatives can meet project objectives and requirements with optimal cost effectiveness and clarifies how transportation planning and traffic diversion principles relate to functional ITS device selections and equipment locations. Methodologies for translating objectives to functional device types, determining device deployment densities and determining the best placement of CCTV cameras and message signs are provided, as are models for evaluating the benefits of design alternatives based on traffic conditions. Readers will learn how to reduce recurrent congestion, improve incident clearance time in non-recurrent congestion, provide real-time incident information to motorists, and leverage transportation management center data for lane control through important new active transportation and demand management (ATDM) methods. Finally, the author examines exciting developments in connected vehicle technologies, exploring their potential to greatly improve safety, mobility and energy efficiency. This resource will greatly benefit all ITS designers and managers and is of pivotal importance for operating agencies performing evaluations to justify operational funding and system expansions.

DOWNLOAD EBOOKThis publication results from growing concern about increasing congestion on urban freeways. It provides an overview of proven traffic control techniques for reducing congestion and improving operations that will be of interest to highway administrators, legislators, and other public officials concerned with the management and operation of freeway systems. This synthesis of past and present practices describes operational and safety problems typical to an urban freeway corridor, a range of options for dealing with these problems, and guidelines for implementing and operating freeway control systems. The report is based on previous research, actual experience from operating freeway control systems in various parts of the United States, and numerous interviews with individuals having responsibility for those systems. General guidance is provided for the planning and implementation of freeway control projects at the executive and administrative levels.
