This book was released on 2005 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: As traffic volumes grow on urban freeways, highway agencies face an ongoing challenge to maintain efficient traffic operations and acceptable levels of service. Increasing the capacity of a freeway by adding a lane can be difficult and expensive if it involves widening the existing roadbed, regrading roadside areas, and/or acquiring additional right-of-way. A number of highway agencies, however, have implemented projects in which a travel lane is added on an urban freeway by restriping the traveled way with narrower lanes, converting all or part of the shoulder to a travel lane, or a combination of both. The traffic operational benefits of such conversions are immediate and obvious, but the safety effects are uncertain. This study addresses these safety effects.

Download or read book Use of Narrow Lanes and Narrow Shoulders on Freeways written by Louis G. Neudorff and published by . This book was released on 2016 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Congested freeways are often located in urban areas with constrained environments and/or rights-of-way where significant widening of the roadway is not practical due to adjacent developments and land use, physical constraints, along with limited availability of funding. Among the strategies for increasing freeway capacity in such constrained environments — and thereby reducing congestion and improving operations — is to add a travel lane within the existing roadway footprint by reducing the widths of the existing lanes and/or shoulders. The additional lane may be utilized by all traffic at all times, as a special use or managed lane that is open only to specific types of vehicles or movements (e.g., High Occupancy Toll (HOT) lane, exit only lane), or only during selected times of the day and/or when congestion warrants opening the lane (e.g., temporary shoulder use). Narrow lanes and shoulders may be applied to add capacity on the freeway mainline and in interchange areas including ramps. This primer provides information to policy makers, transportation agency managers, designers and operators on the use of narrow lanes and narrow shoulders to improve capacity within an existing roadway footprint. Much of the information contained in the primer is presented in the broader context of both Performance Based Planning and Programming (PBPP) and Performance — Based Practical Design (PBPD). Primer contents include case studies on the use of narrow lanes, issues and approaches for analyzing the operational and safety impacts of narrow lanes and narrow shoulders, and the role of transportation systems management and operations (TSMO) in support of narrow lanes operations.
Download or read book Highway Safety Manual written by and published by AASHTO. This book was released on 2010 with total page 886 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Highway Safety Manual (HSM) is a resource that provides safety knowledge and tools in a useful form to facilitate improved decision making based on safety performance. The focus of the HSM is to provide quantitative information for decision making. The HSM assembles currently available information and methodologies on measuring, estimating and evaluating roadways in terms of crash frequency (number of crashes per year) and crash severity (level of injuries due to crashes). The HSM presents tools and methodologies for consideration of 'safety' across the range of highway activities: planning, programming, project development, construction, operations, and maintenance. The purpose of this is to convey present knowledge regarding highway safety information for use by a broad array of transportation professionals"--p. xxiii, vol. 1.

Download or read book Traffic Management written by Simon Cohen and published by John Wiley & Sons. This book was released on 2016-06-15 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transport systems are facing an impossible dilemma: satisfy an increasing demand for mobility of people and goods, while decreasing their fossil-energy requirements and preserving the environment. Additionally, transport has an opportunity to evolve in a changing world, with new services, technologies but also new requirements (fast delivery, reliability, improved accessibility). The subject of traffic is organized into two separate but complementary volumes: Volume 3 on Traffic Management and Volume 4 on Traffic Safety. Traffic Management, Volume 3 of the 'Research for Innovative Transports' Set, presents a collection of updated papers from the TRA 2014 Conference, highlighting the diversity of research in this field. Theoretical chapters and practical case studies address topics such as cooperative systems, the global approach in modeling, road and railway traffic management, information systems and impact assessment.

Book excerpt: 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.
