Management Of Traffic Signal Maintenance

Since the prior edition, traffic signal technology has rapidly progressed as controllers, detection devices, communication, and monitoring systems have become more complex. Developments in traffic engineering concepts, transportation planning, signal design and standards, construction techniques, signal phase and timing (SPaT), regional coordination, asset management, work management, safety, as well as environmental and workplace laws and regulations have had a major effect on current practice. The Handbook is a straightforward reference for the practitioner that will support users in small to large departments or agencies with varying size budgets. The Handbook provides information required to set up and manage a traffic signal program compatible with available financial and technical resources as well as tools for measuring performance. This Handbook is intended primarily for an audience of signal technicians, supervisors, and maintenance operation managers who are vital to ensuring the daily reliable operation of the systems. The Handbook will also be useful for traffic engineers, traffic engineering technicians, and agency managers who seek a better understanding of the technical, logistical, organizational, and financial complexities of traffic signal maintenance.--publisher's website

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.
