Book Field Implementation Testing and Refinement of Density Based Coordinated Ramp Control Strategy

Download or read book Field Implementation Testing and Refinement of Density Based Coordinated Ramp Control Strategy written by and published by . This book was released on 2015 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Twin Cities metropolitan area, freeway ramp metering goes back as early as 1969, when the Minnesota Department of Transportation (MnDOT) first tested ramp metering in an I-35E pilot project. To date, the Twin Cities ramp metering system has grown to include more than 433 ramp meters. Research on better, improved ramp control strategies has continued over the years and MnDOT has implemented minor and major changes in the control logic. Two independent studies both aimed at developing the next generation in ramp metering by focusing on density. Based on these efforts, two new algorithms were developed: the UMN Density and the UMD KAdaptive, named based on the campus at which they were developed. The goal of this project was to implement both algorithms and test them under real conditions. Priorities and technical problems prevented the evaluation of the UMN algorithms, so this report focuses on the evaluation of the UMD KAdaptive algorithm on two freeway corridors in the Twin Cities, MN. The first site, a section of TH-100 northbound between 50th Street and I-394, was selected to compare the then current logic, the Stratified Zone algorithm, with the new one. During the course of this project, the UMD algorithm eventually replaced the Stratified Zone algorithm and was implemented in the entire system. This full deployment also included corridors that were not controlled before. The second evaluation site on eastbound TH-212 was a site that allowed for a with/without control evaluation of the UMD algorithm. This report describes the experiments conducted at both sites and includes a comprehensive review of the state of ramp metering strategies around the world to date.

Book RHODES ITMS MILOS

Download or read book RHODES ITMS MILOS written by Frank W. Ciarallo and published by . This book was released on 2002 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: The RHODES-Integrated Traffic Management System Program addresses the design and development of a real-time traffic adaptive control system for an integrated system of freeways and arterial roads. The goals of this project were to test coordinated, adaptive ramp metering using the Multi-Objective, Integrated, Large-Scale, and Optimized System (MILOS) software on a major urban freeway. A 7-mile eastbound segment of I-10 in Phoenix, just west of the I-10/I-17 Interchange, was chosen as the study area because of the availability of data, and because of recurring congestion.

Book International Encyclopedia of Transportation

Download or read book International Encyclopedia of Transportation written by and published by Elsevier. This book was released on 2021-05-13 with total page 4418 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an increasingly globalised world, despite reductions in costs and time, transportation has become even more important as a facilitator of economic and human interaction; this is reflected in technical advances in transportation systems, increasing interest in how transportation interacts with society and the need to provide novel approaches to understanding its impacts. This has become particularly acute with the impact that Covid-19 has had on transportation across the world, at local, national and international levels. Encyclopedia of Transportation, Seven Volume Set - containing almost 600 articles - brings a cross-cutting and integrated approach to all aspects of transportation from a variety of interdisciplinary fields including engineering, operations research, economics, geography and sociology in order to understand the changes taking place. Emphasising the interaction between these different aspects of research, it offers new solutions to modern-day problems related to transportation. Each of its nine sections is based around familiar themes, but brings together the views of experts from different disciplinary perspectives. Each section is edited by a subject expert who has commissioned articles from a range of authors representing different disciplines, different parts of the world and different social perspectives. The nine sections are structured around the following themes: Transport Modes; Freight Transport and Logistics; Transport Safety and Security; Transport Economics; Traffic Management; Transport Modelling and Data Management; Transport Policy and Planning; Transport Psychology; Sustainability and Health Issues in Transportation. Some articles provide a technical introduction to a topic whilst others provide a bridge between topics or a more future-oriented view of new research areas or challenges. The end result is a reference work that offers researchers and practitioners new approaches, new ways of thinking and novel solutions to problems. All-encompassing and expertly authored, this outstanding reference work will be essential reading for all students and researchers interested in transportation and its global impact in what is a very uncertain world. Provides a forward looking and integrated approach to transportation Updated with future technological impacts, such as self-driving vehicles, cyber-physical systems and big data analytics Includes comprehensive coverage Presents a worldwide approach, including sets of comparative studies and applications

Book Active Traffic Management for Arterials

Download or read book Active Traffic Management for Arterials written by Richard Gerhard Dowling and published by Transportation Research Board. This book was released on 2013 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Active traffic management (ATM) includes a suite of traffic management and control strategies that improve operational efficiency. These strategies are used to manage traffic flow to enhance capacity and safety. This synthesis documents the state of the practice associated with designing, implementing, and operating ATM on arterial roadways."--Preface.

Book Transportation Infostructures

Download or read book Transportation Infostructures written by John Diebold and published by Bloomsbury Publishing USA. This book was released on 1995-05-30 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, the first to result from the Diebold Institute Information-Based Infrastructure Project, explores the links between business and government in the development of intelligent transportation systems (ITS) technology. The work focuses on road and vehicular infrastructures, comparing those of the U.S., Europe, and Japan, and the roles that ITS can play in solving major current and anticipated future transportational problems. Special attention is given to environmental and economic concerns. The world's infrastructure requires refurbishing, but it especially requires rethinking. The computer has transformed business enterprises and now information technology can change our environment. This book explores the benefits and how to achieve them through the use of intelligent transportation systems (ITS). The implementation of ITS will potentially lead to individual drivers, fleet operators, and public transit users saving vast amounts of journey time and fuel, to a significant reduction in pollution and to improved road safety. The Japanese are ahead of the U.S. and Europe in the area of intelligent transportation systems, using position location devices, and electronic maps. Most look at this development as one that helps speed passenger cars, but this book details the economics which point to the technology being equally good for speeding trucks and easing the movement of freight. Traffic avoidance is only part of the problem although route guidance is helpful. Financing of projects in ITS is an important area for innovation and ITS could be a source of revenue to municipalities rather than an expense.
