Book Description
"The purpose of this study was to determine current motorist compliance to RTOR regulations, develop and field test countermeasures for RTOR pedestrian accidents, and develop improved warrants and guidelines for prohibition of RTOR. Based on data from several U.S. cities, only 3.7 percent of all right-turning drivers violate no turn on red (NTOR) signs. However, of drivers with an opportunity to turn right on red, 20 percent violated the sign. At locations with RTOR allowed, 56.9 percent of motorists do not come to a complete stop before turning right on red. Based on conflict and violation data, 30 countermeasures were developed as possible treatments for RTOR-pedestrian accidents. Seven of these were field tested, including an offset stop bar, a red ball (symbolic) NTOR sign, a larger 30x36-in (75x90-cm) NTOR sign, a Look For Turning Vehicles pavement marking, a NTOR When Pedestrians Are Present sign, and an electronic variable message (blank-out) NTOR sign. Several promising applications for the devices were recommended. A critique was made of the current MUTCD guidelines on RTOR prohibition. Based on an analysis of conflicts at 199 intersection approaches, improved guidelines were recommended"--Technical report documentation page

Book Description
This guide is intended to provide information on how to identify safety and mobility needs for pedestrians with the roadway right-of-way. Useful for engineers, planners, safety professionals and decision-makers, the guide covers such topics as: the Walking Environment including sidewalks, curb ramps, crosswalks, roadway lighting and pedestrian over and under passes; Roadway Design including bicycle lanes, roadway narrowing, reducing the number of lanes, one-way/two-way streets, right-turn slip lanes and raised medians; Intersections with roundabouts, T-intersections and median barriers; and Traffic calming designs.

Book Description
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.

Book Description
Get a complete look into modern traffic engineering solutions Traffic Engineering Handbook, Seventh Edition is a newly revised text that builds upon the reputation as the go-to source of essential traffic engineering solutions that this book has maintained for the past 70 years. The updated content reflects changes in key industry standards, and shines a spotlight on the needs of all users, the design of context-sensitive roadways, and the development of more sustainable transportation solutions. Additionally, this resource features a new organizational structure that promotes a more functionally-driven, multimodal approach to planning, designing, and implementing transportation solutions. A branch of civil engineering, traffic engineering concerns the safe and efficient movement of people and goods along roadways. Traffic flow, road geometry, sidewalks, crosswalks, cycle facilities, shared lane markings, traffic signs, traffic lights, and more—all of these elements must be considered when designing public and private sector transportation solutions. Explore the fundamental concepts of traffic engineering as they relate to operation, design, and management Access updated content that reflects changes in key industry-leading resources, such as the Highway Capacity Manual (HCM), Manual on Uniform Traffic Control Devices (MUTCD), AASSHTO Policy on Geometric Design, Highway Safety Manual (HSM), and Americans with Disabilities Act Understand the current state of the traffic engineering field Leverage revised information that homes in on the key topics most relevant to traffic engineering in today's world, such as context-sensitive roadways and sustainable transportation solutions Traffic Engineering Handbook, Seventh Edition is an essential text for public and private sector transportation practitioners, transportation decision makers, public officials, and even upper-level undergraduate and graduate students who are studying transportation engineering.

TRB's National Cooperative Highway Research Program (NCHRP) Report 672: Roundabouts: An Informational Guide - Second Edition explores the planning, design, construction, maintenance, and operation of roundabouts. The report also addresses issues that may be useful in helping to explain the trade-offs associated with roundabouts. This report updates the U.S. Federal Highway Administration's Roundabouts: An Informational Guide, based on experience gained in the United States since that guide was published in 2000.

Book Description
Right turn on red (RTOR) is permitted at most signalized intersections in the United States, primarily to reduce vehicle delays and fuel consumption. However, RTOR increases the risk of motor vehicle crashes and injuries, especially to pedestrians and in urban areas. To reduce the risk of pedestrian crashes at busy intersections, RTOR can be either entirely prohibited, prohibited during specified hours, or prohibited when pedestrians are present. The purpose of this study was to evaluate two methods for restricting RTOR at urban intersections -- traffic signs prohibiting RTOR during specified hours, and signs prohibiting RTOR when pedestrians are present. Fifteen intersections in Arlington, Virginia, where RTOR had previously been permitted at all times were randomly assigned into three groups -- control, no RTOR during specified hours, and no RTOR when pedestrians are present. Signs prohibiting RTOR during specified hours were very effective at increasing the percentage of drivers stopping at stop lines (from 21 to 40 percent), reducing the percentage of drivers turning right on red without stopping (from 32 to 13 percent), and reducing the number of pedestrians yielding to turning vehicles (from 17 to 7 percent). Signs giving drivers discretion to turn right on red based on whether pedestrians are present were not effective.
