Roundabouts


Book Description

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.

The Shaping of Us


Book Description

The spaces we inhabit– from homes and workspaces to city streets—mediate community, creativity, and our very identity. Using insights from environmental psychology, design, and architecture, The Shaping of Us shows how the built and natural worlds subtly influence our behavior, health, and personality. Exploring ideas such as “ruin porn” and “ninja-proof seating,” mysteries of how we interact with the physical spaces around us are revealed. From caves and cathedrals to our current housing crisis and the dreaded open-plan office, Lily Bernheimer demonstrates that, for our well-being, we must reconnect with the power to shape our spaces. Have you ever wondered why we adorn our doorframes with moldings? What does Wikipedia’s open-source technology have to teach us about the history and future of urban housing? What does your desk say about your personality? From savannahs and skyscrapers to co-working spaces, The Shaping of Us shows that the built environment supports our well-being best when it echoes our natural habitats in some way. In attempting to restore this natural quality to human environments, we often look to other species for inspiration. The real secret to building for well-being, Bernheimer argues, is to reconnect humans with the power to shape our surroundings. When people are involved in forming and nurturing their environments, they feel a greater sense of agency, community, and pride, or “collective efficacy.” And when communities have high rates of collective efficacy, they tend to have less litter, vandalism, and violent crime. Playful and accessible, The Shaping of Us is a delightful read for designers, professionals, and anyone wanting to understand how spaces make us tick and how to fix the broken bits of our world.




Traffic Safety and Human Behavior


Book Description

This comprehensive 2nd edition covers the key issues that relate human behavior to traffic safety. In particular it covers the increasing roles that pedestrians and cyclists have in the traffic system; the role of infotainment in driver distraction; and the increasing role of driver assistance systems in changing the driver-vehicle interaction.




Assessing the Benefits and Costs of ITS


Book Description

The 17 chapters in this book, which evolved from a conference on measuring the contributions of ITS sponsored by the California Department of Transportation in February 2002, examine the costs and benefits of ITS in an economic and business policy context. Section 1 examines the broad theme of how and what ITS contributes to the economy and how one makes a business case for ITS. Section 2 includes three chapters on ITS applications in mass transit. Section 3 explores ITS applications in the automobile/highway system. Section 4 considers integrative issues including how ITS is perceived and how it can be positioned to improve surface transportation. This volume will be especially useful to researchers and policy makers working in transportation, transportation engineering, and the economic analysis of transportation systems.

Roundabouts


Book Description

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.
