Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this report are to develop an analytical model to estimate fuel consumption and to investigate the effects of signal timing on fuel consumption. Several numerical experiments, including a variety of geometric configurations, traffic conditions, and signal timing are conducted to test the AFCM estimation capability and to investigate the effects of signal timing on fuel consumption. The results from these experiments indicate that total fuel consumption, with respect to signal cycle time, possesses a convex pattern. In order to analytically establish the relationship between fuel consumption and signal timing, a three-term form is reduced from the AFCM to represent major effects of vehicle characteristics, traffic behavior, and fuel consumption parameters on optimal cycle length. The first term represents vehicle ideal fuel consumption, the second term describes vehicle fuel consumption during acceleration after a stop, and the third term accounts for stochastic effects. Numerical analysis and comparisons show that the optimal cycle lengths from the expression are rather close to those from the AFCM.

Book excerpt: This report summarizes the results of the National Signal Timing Organization Project initiated by the Federal Highway Administration as a fuel conservation effort. The objectives of this project are: 1) to establish credible data on the effectiveness of signal timing optimization; 2) to make signal timing optimization projects easier to do; and 3) to define the resources (cost, level of staff, computer, etc.) required to undertake a signal timing optimization project, so that traffic engineers and administrators can more effectively budget for this activity. The project consisted of the development of the TRANSYT-7F signal timing optimization program User's Manual, and training course, and application of the program in 11 cities nationwide to evaluate the effectiveness of the poptimized signal timing plans and to collect data on the needed resources.

Available in PDF, EPUB and Kindle. Book excerpt: Traditional traffic system management objectives are based on operational efficiency, including capacity, delay reduction, and safety. Generally, criteria for evaluating the effectiveness of signalized intersections are: minimization of total or stopped delay and numbers of stops, minimizing fuel consumption, cost-efficiency, and trade-offs of these factors. Fuel consumption is an important traffic control criterion. A new fuel consumption model called the Analytical Fuel Consumption Model is proposed in this research based on queuing model concepts and different vehicle operational states. The model, aiming to include the impact of traffic characteristics, fuel consumption rates, and control variables, includes different vehicle opeational states describing operations on three intersection elements: inbound approach, intersection itself, and outbound approach. For each element, vehicle operational states are described in three signal cycle stages. Numerical experiments are conducted to calibrate fuel consumption rates of the new model for different traffic volumes and cycle lengths. Results show consistency with those of the TEXAS simulation model. Results for both fuel consumption and delay minimization show that short cycle time lengths are preferred in low volume cases, and likewise, long cycle lengths are preferred in high volume cases.
Download or read book Traffic Signal Timing Manual written by U.s. Department of Transportation and published by CreateSpace. This book was released on 2015-02-20 with total page 286 pages. 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.
