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 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: Management of traffic signal systems is a critical function for every transportation agency. Thanks to advancements in technology, it is now possible to collect large amounts of data at signalized intersections, leading to the development of dozens of performance measures. The TRB National Cooperative Highway Research Program's pre-publication draft of NCHRP Research Report 954: Performance-Based Management of Traffic Signals provides information to help agencies invest in signal performance measures as part of a comprehensive approach to performance-based management. Supplementary materials to the report include a data dictionary and a PowerPoint presentation.

This book was released on 2008 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: "These proceedings contain a summary of the Transportation Research Board conference on U.S. and international approaches to performance measurement for transportation systems that was conducted on September 9-12, 2007, at the Arnold and Mabel Beckman Center of the National Academies in Irvine, California. The theme for this third in a series of international conferences, Better Decisions and Better Communication, was selected to highlight opportunities for and experiences in using performance measurement as a strategic tool to better communicate goals and objectives and results to a wide range of stakeholder groups. Presentations highlighted cases in which performance measures have proved useful in guiding resource allocation decisions, improving day-to-day operations, establishing and demonstrating agency competency and accountability and, in some instances, making the case for more resources. The conference consisted of five plenary sessions, each followed by a series of corresponding, concurrent breakout sessions. The topics of the five plenary sessions were Performance Measures as an Organizational Management Tool to Establish Accountability, Communicating Performance Results Effectively to Your Customers, Data and Tools, Hot Topics (addressing the use of performance measures to gauge the effectiveness of tolling and congestion pricing and other innovative transportation strategies to address sustainability and safety issues), and Performance-Based Contracting and Measuring Project Delivery. Three resource papers were developed for the conference. The conference attracted 180 participants from Canada, Denmark, Germany, Italy, Japan, Mexico, Sweden, the United Kingdom, and the United States and featured 70 transportation specialists offering real-world expertise, from the application of performance metrics to case studies drawn from six countries. This range of experiences provided attendees with a comprehensive overview of the performance measurement techniques and approaches being applied to transportation systems in the United States and abroad."--Pub. desc.

Download or read book Real Time Arterial Traffic Signal Performance Measures written by Christopher M. Day and published by Purdue University Press. 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.

Download or read book Performance Measures for Analyzing Real time Freeway Operations written by Robert E. Brydia and published by . This book was released on 2003 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of real-time performance measurement analyzes feedback from the operational response to freeway incident conditions and provides a quantitative methodology for assessing the impacts of various operational strategies. The significance of this technique is that it can enhance the efficiency of freeway incident management. Even a small percent reduction in the length of an incident would accrue millions of dollars of time-savings for the affected portion of the roadway. The design and construction of a real-time performance measurement system require an understanding of the performance measures and their application to transportation, a review of the state-of-the-practice in performance measurement, and an experimental design on which to build a prototype system.
