This book can act as a fundamental reference book on international practice of road traffic signal control for international researchers and practitioners, with a focus on fixed-time control at isolated intersections. It is neither a summary of findings previously published in literature, nor a handbook or guideline. Potential applications of the book are explained below.
To provide a comprehensive overview of the state-of-the-art practices of road traffic signal control in various countries and regions.
To gain deep understandings of the reasons, underlying background and special considerations for existing differences among the selected countries and regions.
To provide a global summary of useful practical experiences for fixed-time control at isolated intersections.
To help the proper selection of signal timing procedures, methods, and parameters for fixed-time signal control.
To offer helpful suggestions on common principles and improvement countermeasures of road traffic signal control from a global perspective.
Potential audiences of the book include practicing engineers, academic staff and students, hardware and software engineers in signal control manufactures, and maintenance service providers of signal control.
This book consists of 15 chapters in total. This chapter highlights the motivation, scope, purpose, and structure of the book. Chapter 2, Principles of road traffic signal control, addresses major principles of road traffic signal control, which are independent from specific geographical areas, and it provides definitions for basic terms in traffic signal control. Chapters 3-14 are country-specific or region-specific chapters, in which the state-of-the-art practice on fixed-time control at isolated intersections in 16 countries are introduced and discussed. Items include background, history, control strategies, signal timing procedures and methods, signal phasing, critical parameters, special considerations, examples, and state-of-the-art implementations. The sequence of the country-specific chapters is arranged based on geographical areas, that is, America, Europe, Oceania, and Asia, respectively. Chapter 15, Summary, summarizes worldwide successful experiences and common knowledge, and it provides suggestions for the improvement of road traffic signal control.
