Book excerpt: The guidance supplied in this document, Roundabouts: an informational guide, is based on established international and U.S. practices and is supplemented by recent research. The guide is comprehensive in recognition of the diverse needs of transportation professionals and the public for introductory material through design detail, as well as the wide range of potential applications of roundabout intersections. The following topics are addressed: definition of a roundabout and what distinguishes roundabouts from traffic circles; public acceptance and legal issues associated with roundabouts; consideration of all user modes, including heavy vehicles, buses, transit, bicycles, and pedestrians; a methodology for identifying appropriate sites for roundabouts and the range of conditions for which roundabouts offer optimal performance: methodologies for estimating roundabout capacity, delays, and queues with reference to the Highway Capacity Manual; design principles and guidance on safety and geometric design, with reference to applicable national standards such as the AASHTO Policy on Geometric Design of Highways and Streets; guidelines for control features such as signing and pavement markings, with reference to the Manual on Uniform Traffic Control Devices; illumination; and landscaping.

Book excerpt: The roundabouts controlling traffic at the I-17/Happy Valley Road interchange represent Arizona's first application of modern roundabout traffic control in this manner. The construction of roundabouts at this interchange location served to alleviate past congestion and safety issues by reducing off-ramp queues and reducing speeds in the area of the I-17 off-ramp termini. The use of the roundabouts offered flexibility in addressing the complicated traffic interactions of the freeway on- and off-ramps, two-way frontage roads, and Happy Valley Road. Based on this milestone and the overall unique application of roundabout design and function at this particular interchange, the I-17/Happy Valley Road roundabouts were studied to help identify possible improvements that could be incorporated at this location and into future Arizona Department of Transportation roundabout initiatives. The anticipated benefits of the improvements include, but are not limited to, more efficient traffic operations, reduced costs (on average), increased capacity, and improved safety (due to overall slower speeds through the roundabout). The main objectives of this research project include literature review of other state guidelines; evaluation of the roundabouts' design parameters and operation as they relate to capacity and safety; collecting public opinion; and guidelines development. The deliverables of the research project include recommended improvements for the existing roundabouts involving geometric, striping, and signing modifications. Also, the research project culminates in guidelines for the selection, evaluation, and design of roundabouts which provide details on the facets of roundabout use as it relates to Arizona.
Book Synopsis Roundabouts as Safe and Modern Solutions in Transport Networks and Systems by : Elżbieta Macioszek
Download or read book Roundabouts as Safe and Modern Solutions in Transport Networks and Systems written by Elżbieta Macioszek and published by Springer. This book was released on 2018-07-31 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a collection of guidelines that will be particularly useful to those making decisions concerning roundabouts as safe and modern solutions in transport networks and systems. The decision-making support systems described here will interest those who face the challenge of finding solutions to problems concerning modern transport systems on a daily basis. Consequently, the book is chiefly intended for local authorities involved in planning and preparing development strategies for specific transport-related issues (in both urban and regional contexts), as well as for representatives of business and industry who are directly engaged in the implementation of traffic engineering solutions. The guidelines provided in the respective chapters help to address the given problem soundly, and to simplify the selection of an appropriate strategy. The topics covered include traffic conditions and the performance of single-lane, two-lane and turbo roundabouts, road traffic safety analysis, analysis of road traffic safety improvements, surrogate safety measures at roundabouts, analysis of pedestrian behavior at pedestrian crossings with public transport vehicles, methods for assessing vehicle motion trajectory at single-lane roundabouts using visual techniques, making compact two-lane roundabouts effective for vulnerable road users, concepts for wireless electric vehicle charging near roundabouts, work zones, and temporary traffic control at roundabouts. Since the book also considers new approaches to theoretical models (including modeling roundabout capacity, models of critical gaps and follow-up headways for turbo roundabouts, and estimating roundabout delay while taking into account pedestrian impact), it will also appeal to researchers and scientists studying these problems. The book gathers selected papers presented at the 15th Scientific and Technical Conference “Transport Systems. Theory and Practice”, organized by the Department of Transport Systems and Traffic Engineering, Silesian University of Technology in Katowice, Poland on September 17–19, 2018.

Book Synopsis Intersections Control and Safety by : Antonio Pratelli
Download or read book Intersections Control and Safety written by Antonio Pratelli and published by WIT Press. This book was released on 2013-05-22 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Starting off a new series on Transport Systems and Traffic Engineering the book aims to help bridge the gap between research and practice, encouraging a critical dialogue in different, specific, subjects spanning innovation, development and technology transfer. Those who offer innovation often do not meet the immediate needs of practitioners, especially in the traditional field of civil engineering. Still, the adequate diffusion of research results and wisdom derived from practical experience are crucial to both theoretical underpinnings and technical applications.The papers forming this book are devoted to intersection control and safety and have been selected bearing in mind the criteria stated above. That is, these papers provide both scholarly contribution as well as vision for application.As a general rule, about one-third of all highway crashes happen at intersections. This rule holds for many different countries. Intersection crashes also represent a significant portion of serious injury crashes, and by right are receiving considerable attention from researchers and practitioners alike. This book is therefore devoted to relevant safety aspects of road intersections and innovative features in design and operations that may address the intersection crash problem. The thirteen papers are more or less equally devoted to roundabouts and signals. These papers cover many of the most recent and emerging issues related to intersection control and safety. Topics range from design details to driver perception, from pedestrians behaviour to signal timing, and from capacity models to red-light running. The book will be useful for those wishing to expand their knowledge of this ever important subject area.
