Systems Engineering Processes for Developing Traffic Signal Systems


Book Description

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 307: Systems Engineering Processes for Developing Traffic Signal Systems discusses the systems engineering techniques available to traffic signal systems and identifies the key processes in a number of traffic signal systems engineering areas.




Traffic Control Systems Handbook


Book Description

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.




Intelligent Transportation Systems


Book Description

Intelligent 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.

ITS Sensors and Architectures for Traffic Management and Connected Vehicles


Book Description

An intelligent transportation system (ITS) offers considerable opportunities for increasing the safety, efficiency, and predictability of traffic flow and reducing vehicle emissions. Sensors (or detectors) enable the effective gathering of arterial and controlled-access highway information in support of automatic incident detection, active transportation and demand management, traffic-adaptive signal control, and ramp and freeway metering and dispatching of emergency response providers. As traffic flow sensors are integrated with big data sources such as connected and cooperative vehicles, and cell phones and other Bluetooth-enabled devices, more accurate and timely traffic flow information can be obtained. The book examines the roles of traffic management centers that serve cities, counties, and other regions, and the collocation issues that ensue when multiple agencies share the same space. It describes sensor applications and data requirements for several ITS strategies; sensor technologies; sensor installation, initialization, and field-testing procedures; and alternate sources of traffic flow data. The book addresses concerns related to the introduction of automated and connected vehicles, and the benefits that systems engineering and national ITS architectures in the US, Europe, Japan, and elsewhere bring to ITS. Sensor and data fusion benefits to traffic management are described, while the Bayesian and Dempster–Shafer approaches to data fusion are discussed in more detail. ITS Sensors and Architectures for Traffic Management and Connected Vehicles suits the needs of personnel in transportation institutes and highway agencies, and students in undergraduate or graduate transportation engineering courses.










The Engineering Design of Systems


Book Description

Comprehensive resource covering methods to design, verify, and validate systems with a model-based approach, addressing engineering of current software-centric systems The newly revised and updated Fourth Edition of The Engineering Design of Systems includes content addressing model-based systems engineering, digital engineering, digital threads, AI, SysML 1.0 and 2.0, digital twins, and GENESYS software. The authors explore system and software-centric architecture, allocations, and logical and physical architecture development, including revised terminologies for a variety of subsections throughout. Composed of 15 chapters, this book includes important new sections on modeling approaches for middle-out engineering, reverse engineering, and agile systems engineering, with a separate section on emerging trends within systems engineering to explore the most update-to-date methods. The authors include comprehensive diagrams and a separate chapter on a complete exercise of the System Engineering process, ranging from the operational concept to integration and qualification. To aid in reader comprehension and retention of concepts, the text is embedded with problems at the end of each chapter, along with relevant case studies. Sample topics covered in The Engineering Design of Systems include: Structural system models to executable models, verification and validation on systems of systems, and external systems and context modeling Digital engineering, digital threads, artificial/augmented intelligence (AI), stakeholder requirements, and scientific foundations for systems engineering Quantifying a context and external systems’ model, including intended and unintended inputs, both deterministic and non-deterministic Functional architecture development, logical and physical architecture development, allocated architecture development, interface design, and decision analysis for design trades The Engineering Design of Systems is highly suitable as a main text for undergraduate and graduate students studying courses in system engineering design, systems architecture, and systems integration. The text is also valuable as a reference for practicing system architects, systems engineers, industrial engineers, engineering management professionals, and systems integrators.
