This report summarizes the results of the work performed under the project Study of Optimal Travel Speed Limits for Shared Traffic. The objectives of the research were to determine if a 25-mph speed limit addresses safety needs of bicyclists and pedestrians sharing roadway with vehicles, to recommend a method to assess and set speed limits for shared use of public right of way by motor vehicle, bicycle and pedestrian traffic, and to recommend optimum speed limits for shared use bicycle/motor vehicle traffic in terms of different perspectives for low volumes, low speeds, and road geometry.
A new way forward for sustainable quality of life in cities of all sizes Strong Towns: A Bottom-Up Revolution to Build American Prosperity is a book of forward-thinking ideas that breaks with modern wisdom to present a new vision of urban development in the United States. Presenting the foundational ideas of the Strong Towns movement he co-founded, Charles Marohn explains why cities of all sizes continue to struggle to meet their basic needs, and reveals the new paradigm that can solve this longstanding problem. Inside, you’ll learn why inducing growth and development has been the conventional response to urban financial struggles—and why it just doesn’t work. New development and high-risk investing don’t generate enough wealth to support itself, and cities continue to struggle. Read this book to find out how cities large and small can focus on bottom-up investments to minimize risk and maximize their ability to strengthen the community financially and improve citizens’ quality of life. Develop in-depth knowledge of the underlying logic behind the “traditional” search for never-ending urban growth Learn practical solutions for ameliorating financial struggles through low-risk investment and a grassroots focus Gain insights and tools that can stop the vicious cycle of budget shortfalls and unexpected downturns Become a part of the Strong Towns revolution by shifting the focus away from top-down growth toward rebuilding American prosperity Strong Towns acknowledges that there is a problem with the American approach to growth and shows community leaders a new way forward. The Strong Towns response is a revolution in how we assemble the places we live.
TRB Special Report 254 - Managing Speed: Review of Current Practices for Setting and Enforcing Speed Limits reviews practices for setting and enforcing speed limits on all types of roads and provides guidance to state and local governments on appropriate methods of setting speed limits and related enforcement strategies. Following an executive summary, the report is presented in six chapters and five appendices.
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.
This Handbook provides comprehensive coverage of all of the major factors that underpin our understanding of urban and transport planning in the developed world. Combining urban and transport planning in one volume, the chapters present the state of the art as well as new research and directions for the future. The contributions from leading international academics at the forefront of their fields consider transport and urban planning from a number of different perspectives including historical, policy and strategy dimensions, appraisal and financing of options, planning and design of urban areas and the management of transport and urban systems. Examples and practical guides from the developed world are included along with a detailed discussion of the emerging issues. The Handbook provides an essential reference to all of the key points on the topic as well as signalling areas of concern and future research paths. Academics, researchers, students, policymakers and practitioners will find it a constant source of information and guidance.
Driving is a fact of life. We are all spending more and more time on the road, and traffic is an issue we face everyday. This book will make you think about it in a whole new light. We have always had a passion for cars and driving. Now Traffic offers us an exceptionally rich understanding of that passion. Vanderbilt explains why traffic jams form, outlines the unintended consequences of our attempts to engineer safety and even identifies the most common mistakes drivers make in parking lots. Based on exhaustive research and interviews with driving experts and traffic officials around the globe, Traffic gets under the hood of the quotidian activity of driving to uncover the surprisingly complex web of physical, psychological and technical factors that explain how traffic works.
This book constitutes the refereed proceedings of the two workshops held at the 14th International Conference on Principles and Practice of Multi-Agent Systems, PRIMA 2011, held in Wollongong, Australia, in November. The workshops were, Workshop on Agent Based Simulation for a Sustainable Society (ABSSS 2011) and International Workshop on Multi-Agent Smart Computing (MASmart 2011). The 8 papers presented were carefully reviewed and selected from various submissions. The papers cover topics from agent based simulation for a sustainable society and on multi-agent smart computing.
