Download or read book Comparative Analysis of Roundabout Capacity Analysis Methods written by Abdullah Ayed F. Alqahtani and published by . This book was released on 2019 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the Washington State Department of Transportation (WSDOT), the use of roundabouts has been increasing due to its numerous benefits. Compared to other types of intersection (conventional) controls, a roundabout improves traffic safety, reduces delays, lessens the severity of crashes, improves traffic flow, and minimizes maintenance costs. The Federal Highway Administration (FHWA) report that in some previous study findings the injury and fatality crashes were reduced by 78-82% after converting signalized intersections to roundabouts. This study used data from the City of Fairborn, Ohio, for a project where they were preparing to replace a 50-years old signalized intersection (at Kauffman Avenue and Colonel Glenn Highway) with a modern roundabout. This signalized intersection experienced 18 crashes between 2013 and 2015. The modern roundabout was scheduled to be constructed in 2019 by the City of Fairborn, and it was designed with three legs (similar to the existing intersection layout), with three entries, three exits, and one circulating lane. Two software programs were used in this study, which are RODEL and Highway Capacity Software (HCS7), and two manual methods were also used, which are 2010 Federal Highway Administration method (Roundabouts: An Informational Guide) and 2016 Highway Capacity Manual (HCM 6). The main aim of this study was to compare capacity analysis results to the same data inputs among all methods. The results from this study are helpful in explaining the performance of each method and provide an understanding of analyzing roundabout capacity. The comparative results for each method include capacity, volume-to-capacity ratio, control delay, level of service (LOS), 95th percentile queue length for each approach/lane, and the entire intersection control delay and LOS. The results show that RODEL (geometric model) predicted the largest capacity, the smallest volume-to-capacity, the lowest delay, the best LOS, the shortest 95% queue length, and the lowest delay and best LOS for entire intersection. This supports the conclusions of previous studies. The FHWA 2010 results were quite the opposite; estimated the lowest capacity for the same traffic and geometric inputs, largest queues, delays and volume-to-capacity ratio. The results from HCS7, 2016 HCM (HCM 6), 2010 FHWA and RODEL (HCM 2016 model) were similar because they use the same methodology. HCS7 software automates the HCM6 methodologies.
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.

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.
