Traveler Response to Transportation System Changes


Book Description

From a transportation and community perspective, objectives of pedestrian and bicycle facility improvements have evolved to include numerous aspects of providing viable and safe active transportation options for all ages, abilities, and socioeconomic groups. Pedestrian and bicycle facilities appear overall to benefit the full spectrum of society perhaps more broadly than any other provision of transportation. A challenge in non-motorized transportation (NMT) benefit analysis is to adequately account for all the different forms in which pedestrian and bicycle facilities provide benefit. In this report, new as well as synthesized research is presented. This chapter examines pedestrian and bicyclist behavior and travel demand outcomes in a relatively broad sense. It covers traveler response to NMT facilities both in isolation and as part of the total urban fabric, along with the effects of associated programs and promotion. It looks not only at transportation outcomes, but also recreational and public health outcomes. This chapter focuses on the travel behavior and public health implications of pedestrian/bicycle areawide systems; NMT-link facilities such as sidewalks, bicycle lanes, and on-transit accommodation of bicycles; and node-specific facilities such as street-crossing treatments, bicycle parking, and showers. Discussion of the implications of pedestrian and bicycle "friendly" neighborhoods, policies, programs, and promotion is also incorporated. The public health effects coverage of this chapter, and associated treatment of walking and bicycling and schoolchild travel as key aspects of active living, have been greatly facilitated by participation in the project by the National Center for Environmental Health--part of the Centers for Disease Control and Prevention (CDC). This pivotal CDC involvement has included supplemental financial support for the Chapter 16 work effort. It has also encompassed assistance with research sources and questions, and draft chapter reviews by individual CDC staff members in parallel with TCRP Project B-12A Panel member reviews (see "Chapter 16 Author and Contributor Acknowledgments". TCRP Report 95: Chapter 16, Pedestrian and Bicycle Facilities will be of interest to transit, transportation, and land use planning practitioners; public health professionals and transportation engineers; land developers, employers, and school administrators; researchers and educators; and professionals across a broad spectrum of transportation, planning, and public health agencies; MPOs; and local, state, and federal government agencies. This chapter is complemented by illustrative photographs provided as a "Photo Gallery" at the conclusion of the report. In addition, PowerPoint slides of the photographs in full color are available on the TRB website at http://www.trb.org/Main/Blurbs/167122.aspx.




Recent Roadway Geometric Design Research for Improved Safety and Operations


Book Description

RB’s National Cooperative Highway Research Program (NCHRP) Synthesis 432: Recent Roadway Geometric Design Research for Improved Safety and Operations reviews and summarizes roadway geometric design literature completed and published from 2001 through early 2011, particularly research that identified impacts on safety and operations.




Current Issues in the Education of Students with Visual Impairments


Book Description

International Review of Research in Developmental Disabilities is an ongoing scholarly look at research into the causes, effects, classification systems, and syndromes of developmental disabilities. Contributors come from wide-ranging perspectives, including genetics, psychology, education, and other health and behavioral sciences. The current volume, number 46, addresses current issues in the education of students with visual impairments. Topics covered include the expanded core curriculum for students with visual impairment; assistive technology; Braille reading comprehension; communication development; orientation and mobility issues, and more. Provides the most recent scholarly research in the study of developmental disabilities A vast range of perspectives is offered, and many topics are covered An excellent resource for academic researchers




Alternative Types of Roundabouts


Book Description

This book presents a history of roundabouts, an introduction to their design, calculations of their capacity and traffic-safety features. It describes the key features of standard roundabouts and their limitations. Alternative types of roundabouts are a fairly recent development and have only been implemented in a few countries to date. The book illustrates a broad variety of these recent alternative types of roundabouts, as well as proposed types still in the development phase, explaining for each the specific needs it meets, its advantages and drawbacks. In closing, the book offers an outlook on the role of roundabouts in future street traffic.




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.
