This book was released on 2015-09-01 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Designers and traffic engineers have to make decisions on selecting a pedestrian treatment whenever designing a new pedestrian facility or retrofitting an existing one. The goal is either to provide or improve pedestrian safety at pedestrian crossing facilities, including controlled locations of signalized intersections and approaches with stop and yield signs, and uncontrolled locations of intersections and midblock sites. Currently, the Indiana Department of Transportation (INDOT) has limited resources on pedestrian treatment selection that does not take into consideration key elements such as number of lanes and the existence of a raised median. Therefore, there is a need to find a more detailed and comprehensive approach to providing guidelines when deciding on a pedestrian crossing treatment. The approach has to be practical and can be easily utilized by traffic and design engineers, planners, and other constituents.Most of the State DOTs developed their guidelines on pedestrian crossing treatment based on several resources. However, the 2002 FHWA-RD-01-075 study titled "Safety Effects of Marked Vs. Unmarked Crosswalks at Uncontrolled Locations" was adopted by several states either "as is," with some modifications, or referenced as a source on pedestrian crosswalk selection. State DOTs mainly use standards and guidelines from the National MUTCD, Part 3 and NCHRP Report 672 for roundabout crosswalk markings. In general, there are no clear warrants for grade separation treatment. In addition, there is a need for a national and comprehensive study to develop practical guidelines on pedestrian crossing treatments, especially on multilane roadways, complex intersections, and when the speed is 45 mph or more.This study proposed guidelines on crosswalk markings and treatment selection of pedestrian crossings based on a synthesis of federal and state reports, guidelines, design manuals, polices, and other relevant publications. It is recommended to adopt these guidelines as a reference for pedestrian treatment selection at INDOT.

This book was released on 2017 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: "TRB's National Cooperative Research Program (NCHRP) Report 841: Development of Crash Modification Factors for Uncontrolled Pedestrian Crossing Treatments quantifies the safety benefits of four types of pedestrian crossing treatments—rectangular rapid flashing beacons, pedestrian hybrid beacons, pedestrian refuge islands, and advanced YIELD or STOP markings and signs—and presents a crash modification factor (CMF) for each treatment type. This information, which is suitable for inclusion in the American Association of State Highway and Transportation Officials (AASHTO) Highway Safety Manual, the U.S. Federal Highway Administration's (FHWA's) CMF Clearinghouse, and other guidance, will be valuable to transportation agencies in choosing the appropriate crossing treatment for uncontrolled pedestrian crossings." - Publisher description

This book was released on 2016-01-26 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: Get a complete look into modern traffic engineering solutions Traffic Engineering Handbook, Seventh Edition is a newly revised text that builds upon the reputation as the go-to source of essential traffic engineering solutions that this book has maintained for the past 70 years. The updated content reflects changes in key industry standards, and shines a spotlight on the needs of all users, the design of context-sensitive roadways, and the development of more sustainable transportation solutions. Additionally, this resource features a new organizational structure that promotes a more functionally-driven, multimodal approach to planning, designing, and implementing transportation solutions. A branch of civil engineering, traffic engineering concerns the safe and efficient movement of people and goods along roadways. Traffic flow, road geometry, sidewalks, crosswalks, cycle facilities, shared lane markings, traffic signs, traffic lights, and more—all of these elements must be considered when designing public and private sector transportation solutions. Explore the fundamental concepts of traffic engineering as they relate to operation, design, and management Access updated content that reflects changes in key industry-leading resources, such as the Highway Capacity Manual (HCM), Manual on Uniform Traffic Control Devices (MUTCD), AASSHTO Policy on Geometric Design, Highway Safety Manual (HSM), and Americans with Disabilities Act Understand the current state of the traffic engineering field Leverage revised information that homes in on the key topics most relevant to traffic engineering in today's world, such as context-sensitive roadways and sustainable transportation solutions Traffic Engineering Handbook, Seventh Edition is an essential text for public and private sector transportation practitioners, transportation decision makers, public officials, and even upper-level undergraduate and graduate students who are studying transportation engineering.

Book excerpt: This report describes two related studies intended to address double-lane roundabout accessibility issues for visually impaired pedestrians. The first study was conducted on a closed course to evaluate the feasibility of a pavement treatment to alert blind pedestrians when vehicles have yielded to them. The second study examined drivers' yielding behavior at a two-lane roundabout and the effectiveness of the same roadway treatment in an operational environment. In the first study, there were two experimental conditions: a control condition and a treatment condition in which rumble strip-like devices were placed on the roadway surface. Seven individuals who have severe visual impairments participated. Participants stood at a crosswalk and used hand signals to indicate when they detected vehicles stopping or departing after a stop. Compared to the control condition, the sound strips treatment increased the probability of detecting stopped vehicles, and decreased by more than a second the amount of time needed to make a detection; however, the treatment did not reduce approaching the crosswalk. The second study was an experiment conducted at an operating roundabout. In that environment the rumble strip-like treatment was not effective, probably because the majority of vehicles stopped in the circular roadway before crossing over the rumble strips. A Yield to Pedestrians, State Law sign that was placed in the roundabout exit between the two travel lanes resulted in an increase in drivers' yielding from 11 percent of vehicles in the control condition to 16 percent in the experimental condition. It was concluded that the treatments explored in these studies do not appear promising for double-lane roundabouts, but should be explored further to see if they might work at single-lane crossings.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides in-depth coverage of all aspects of pelvic ring fractures and their management. The opening chapters supply essential information on surgical anatomy, biomechanics, classification, clinical evaluation, radiological diagnostics, and emergency and acute management. The various operative techniques, including navigation techniques, that have been established and standardized over the past two decades are then presented in a step-by-step approach. Readers will find guidance on surgical indications, choice of approaches, reduction and fixation strategies, complication management, and optimization of long-term results. Specific treatment concepts are described for age-specific fractures, including pediatric and geriatric injuries, and secondary reconstructions. Pelvic ring fractures represent challenging injuries, especially when they present with concomitant hemodynamic instability. This book will help trauma and orthopaedic surgeons at all levels of experience to achieve the primary treatment aim of anatomic restoration of the bony pelvis to preserve biomechanical stability and avoid malunion with resulting clinical impairments.
