Book Description
This report serves as a comprehensive guide to traffic signal timing and documents the tasks completed in association with its development. The focus of this document is on traffic signal control principles, practices, and procedures. It describes the relationship between traffic signal timing and transportation policy and addresses maintenance and operations of traffic signals. It represents a synthesis of traffic signal timing concepts and their application and focuses on the use of detection, related timing parameters, and resulting effects to users at the intersection. It discusses advanced topics briefly to raise awareness related to their use and application. The purpose of the Signal Timing Manual is to provide direction and guidance to managers, supervisors, and practitioners based on sound practice to proactively and comprehensively improve signal timing. The outcome of properly training staff and proactively operating and maintaining traffic signals is signal timing that reduces congestion and fuel consumption ultimately improving our quality of life and the air we breathe. This manual provides an easy-to-use concise, practical and modular guide on signal timing. The elements of signal timing from policy and funding considerations to timing plan development, assessment, and maintenance are covered in the manual. The manual is the culmination of research into practices across North America and serves as a reference for a range of practitioners, from those involved in the day to day management, operation and maintenance of traffic signals to those that plan, design, operate and maintain these systems.

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.

Book Description
The Texas Department of Transportation (TxDOT) operates thousands of traffic signals along state highways in the state of Texas. The operation of these signals is the responsibility of the TxDOT districts in which they are located. This local operation serves Texas motorists well, but it has also resulted in differences in practice across the state. TxDOT research project 0-5629 developed the Traffic Signal Operations Handbook to (1) provide a uniform basis for signal operation throughout the state and (2) identify cost-effective procedures for maintaining safe and efficient signal operation. This report documents the development and conduct of a two-year series of workshops to share information with TxDOT engineers and technicians regarding the cost-effective design and operation of signalized intersections. Information in the Handbook was used as the basis for the workshop. The workshop was one day in length and was offered at six venues in Texas. Workshop topics include basic signal controller timing, coordination timing, signal phasing, rail preemption, detection design, and diamond interchange timing. The workshop participants applied the Handbook guidelines in several examples using a spreadsheet program called the Texas Signal Coordination Optimizer (TSCO).

Book Description
This project report summaries research and implementation of signal system communications and improved signal control. An investigation of available signal system communication technologies and media identified spread spectrum radio as an effective, inexpensive, and flexible alternative. As part of the project, a radio communications system was selected and installed at five signalized intersections along US 281 in Falfurrias, Texas. Closed loop system software was then installed to coordinate the previously isolated, actuated intersections. The end result was improved traffic control, improved traffic flow, and remote system monitoring for those responsible for signal maintenance. A second aspect of the project focused on developing real-time control functionality that would make use of the communications system. The Texas Department of Transportation's Dynamic Arterial Responsive Traffic System (DARTS) Specification provided a public domain, real-time signal coordination algorithm that suited this purpose. Simulators were developed by the Texas Transportation Institute to determine the effectiveness of DARTS installed in Falfurrias. Results show an average 18 percent reduction in travel time on US 281 and indicate the potential for DARTS to reduce arterial travel time. As an added project benefit, the simulation software developed for this project can be used to determine DARTS applicability at any given field site, and it can be used to train personnel in DARTS use and calibration.
