"The ... case study showcases two successful low-cost strategies that measurably improved safety at 33 signalized intersections in Detroit and Highland Park, MI. The treatments included providing an all-red clearance interval and increasing the size of the signal lens for the red, yellow and green indications."--Web site.

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 321: Roadway Safety Tools for Local Agencies examines the safety tools and procedures that are practical and relatively easy to apply, and that can be implemented by agencies with limited financial support and personnel. Recognizing the wide variation in the operations and responsibilities of local agencies, the report acknowledges that the level of expertise in transportation safety analysis also varies greatly.

"Recommended."--CHOICE: Current Reviews for Academic Libraries "Coughlin and DíAmbrosioís edited volume is a welcome contribution to highlighting this issue for gerontologists. The collection is an informative and useful reference for students, researchers, practitioners, planners, and policy analysts"--The Gerontologist This solution-focused volume fills a gap in the literature by addressing the key issues around mobility and transportation for the aging Baby Boomer generation--issues that will be significantly different than those of previous generations of older adults. This new generation, many of whom will continue to work past the traditional retirement age and expect to pursue an active lifestyle, may have to confront new transportation technology, the need to use public transportation, and ways to continue driving safely as their eyesight fades and reaction time slows down. This volume examines many of the issues faced by policymakers, transportation officials, vehicle manufacturers, health and human services professionals, and aging adults themselves as the largest generation prepares to enter late adulthood. The volume's editors are both at the MIT AgeLab, whose multi-disciplinary team designs, develops and deploys innovations to enhance quality of life for aging populations. Through the contributions of a diverse group of theorists and practitioners, including recommendations from the National Older Driver Safety Advisory Council, a collaboration between AARP's Driver Safety Program and the MIT AgeLab, the book discusses several key topics pertinent to Aging America and transportation. Among them are the changing demographics of the population, how this generation's lifestyle choices affect mobility, technology trends in private vehicles, changes in the infrastructure and transportation system, the "new" older driver, and issues of safety and education among older drivers. This book also explores practical solutions and strategies, such as new transportation options and innovations that will significantly impact the future of mobility for older adults, for keeping these seniors active and mobile well into their later years. Key Features: Focuses on the unique mobility needs of the aging Baby Boomer generation Provides practical solutions and strategies for policy changes to enhance the mobility of older adults Examines issues faced by policymakers, transportation officials, vehicle manufacturers, health and human services professionals, and aging adults Discusses strategies for updating the infrastructure and transportation system, driving safety education for older drivers, and trends in private vehicle innovations

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.

With the advancement of implementation for a novel traffic control device, the Flashing Yellow Arrow (FYA), agencies across the country have continually sought strategies to improve intersection operations and safety, specifically with respect to the left-turn application. More so, permissive left-turn intervals have been communicated to drivers using several traffic signal indications; however, most frequently these phases are represented through the circular green (CG) ball and more recently, the FYA. Previous research in this area determined that the FYA indication produced the most effective communication of permissive left-turns. Further, this previous research led to the inclusion of the FYA in the 2009 edition of the Manual on Uniform Traffic Control Devices (MUTCD). In recent years, agencies across the country have embraced the implementation of the FYA for permissive left-turns. However, there remains a lack of national guidance on the definition of change and clearance intervals for transitioning between protected and permissive left-turns. Complicating the matter is the connection between traditional signal phasing/design and human factors. Investigation through driver comprehension and real-world operations will allow us to not only evaluate current conditions, but also experimental and future conditions. Recommendations provided from this research will ultimately offer agencies with the strategies for the most effective transition from a protected left-turn to a permissive left-turn phase.
