This book was released on 2005 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objectives of this research project were: (1) to develop an active advance warning device (AAWD) comprised of an actuated flashing beacon supplement to a conventional SCHOOL BUS STOP AHEAD sign (S3-1) and (2) to evaluate its effect on driver performance and safety through school bus loading and unloading zones. Secondary objectives were to summarize system components and costs, develop an activation strategy, review the liability risk, review national experience related to safety, and provide guidance regarding specifications and use in Texas. With respect to safety, 37 of 46 studies reported a positive effect resulting from AAWDs. Findings from field studies conducted in Texas also suggest favorable results with confirmed reductions in vehicle approach speeds when the flashing beacon was activated. Costs for the final AAWD are estimated to be 2,000 dollars for the S3-1 sign and flashing beacons and 2,600 dollars for the flashing beacon activation system, not including sign installation or ongoing maintenance and operations costs. A review of published literature and historic case law suggests minimal additional liability risk above what is already experienced by transportation departments. Unique areas of risk relate to "jurisdictional responsibility" for establishing, operating, and maintaining school bus loading and unloading zones and the hazard expectation tied to the flashing beacon activation (i.e., motorists may not exercise the same degree of caution when the bus is not present and the beacons are not flashing despite children being present at the bus stop). Given the favorable safety impacts, the low system cost, and the minimal additional liability risk incurred, the AA WD is recommended for further implementation.

Available in PDF, EPUB and Kindle. Book excerpt: This report contains the results of the NC Department of Transportation research project Placement of Detection Loops on High Speed Approaches to Traffic Signals (HWY 2007-13). The goal of this project was to determine the best places to locate detectors on the approaches to high-speed signalized intersections and the best signal control strategy to employ in conjunction with those sensor placement ideas to minimize dilemma zone occurrences.

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.
