This book was released on 2014-03-26 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is a synthesis of research carried out on traffic signal performance measures based on high-resolution controller event data, assembled into a methodology for performance evaluation of traffic signal systems. High-resolution data consist of a log of discrete events such as changes in detector and signal phase states. A discussion is provided on the collection and management of the signal event data and on the necessary infrastructure to collect these data. A portfolio of performance measures is then presented, focusing on several different topics under the umbrella of traffic signal systems operation. System maintenance and asset management is one focus. Another focus is signal operations, considered from the perspectives of vehicle capacity allocation and vehicle progression. Performance measures are also presented for nonvehicle modes, including pedestrians, and modes that require signal preemption and priority features. Finally, the use of travel time data is demonstrated for evaluating system operations and assessing the impact of signal retiming activities.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was to examine the type of performance measures that could be collected at an intersection and develop a system for automatically collecting these performance measures in the field.. We began the research by conducting an assessment ofthe needs of the Texas Department of Transportation (TxDOT) practitioners for an automated system to collect intersection and traffic signal performance measures. We then examined capabilities of some of the existing traffic signal controllers and detection systems to produce the desired performance measures. Based on the findings of the needs assessments and an evaluation of the limitation of the existing detection system, we developed a series of innovative performance measures that practitioners could use to assess traffic operations and the effectiveness of the signal timing at intersections. We then developed a prototype system for automatically collecting these data in the field. We installed the prototype system in two different locations that exhibited different operating characteristics and assessed the ability of the system to collect meaningful and appropriate performance measures.

This book was released on 2015-12-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This report discusses uses of and requirements for performance measures in traffic signal systems facilitated by high-resolution controller event data. Uses of external travel time measurements are also discussed. The discussion is led by a high-level synthesis of the systems engineering concepts for traffic signal control, considering technical and nontechnical aspects of the problem. This is followed by a presentation of the requirements for implementing data collection and processing of the data into signal performance measures. The remaining portion of the report uses an example-oriented approach to show a variety of uses of performance measures for communication and detector system health, quality of local control (including capacity allocation, safety, pedestrian performance, preemption, and advanced control analysis), and quality of progression (including evaluation and optimization).

This book was released on 2008-04-01 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing demand for highway system capacity compels transportation agencies to extract as much capacity as possible from existing systems. Traffic signals represent a major component of highway systems. Improvement of traffic signal operation requires accurate performance measures. Despite recent improvements in computing technology, traffic signal controllers are currently not able to capture useful performance measures on a cycle-by-cycle basis. This report presents a set of performance measures that could be collected on a cycle-by-cycle basis by a traffic signal controller given the capability to log phase indications and detector actuations. The performance measures investigated here include the volume-to-capacity ratio and arrival type defined by the Highway Capacity Manual. The effectiveness of these performance measures in evaluating operation at a traffic signal is demonstrated in two comparative case studies. The first study investigates the impact of actuating a portion of the coordinated phases at a coordinated arterial intersection. The second study investigates the results of retiming a traffic signal on a coordinated arterial.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2004 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the first year of a two-year research project to develop potential measures that might be used to assess the performance of traffic signal timing at isolated intersections. This report summarizes the findings of a series of interviews we conducted to detennine what measures the Texas Department of Transportation (TxDOT) is currently using to assess the perfonnance of their traffic signals and how data for these perfonnance measures are collected. It also contains the results of an examination of existing controller and detection technologies to determine what capabilities they have to produce performance measures. The report presents several proposed measures that can be used to assess the performance of signal timing and the procedures for computing these performance measures using existing detection technologies.
