Download or read book Accident Experience Involving Soundwalls written by L. L. Seamons and published by . This book was released on 1990 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a before-and-after study of soundwall installations which indicates that the installation of soundwalls did not significantly increase the total accident rate. The study involved comparing the accident experiences among groups of soundwall installations; a group being defined by base or protection type and distance from the edge of the traveled way. Soundwall accidents were also compared with all urban freeway accidents. All available collision reports were read and examined for angle of impact. Fatal collision reports were further examined for causative factors. The final conclusions are that the data in this report does not conflict with Caltrans' newly revised soundwall base type policy and actually lends support. The support is qualified because of the small data samples available for some aspects of the study.

Download or read book Evaluation of Operational Efficiencies Cost and Accident Experience of Four Phase Single Point Urban Interchanges written by Jim C. Lee and published by . This book was released on 2002 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research compares two interchange types, the Tight Urban Diamond Interchange (TUDI) and the Four Phase Single Point Urban Interchange (40SPUI). The 40SPUI is referred to in this report as a Single Point Urban Interchange with Frontage Roads (SPUI/F). The objectives of this research were to: (1) evaluate the SPUI/F based on available accident data and conflict analysis techniques, right-of-way and construction costs, and operating efficiency; (2) compare the performance of the SPUI/F and the TUDI; (3) evaluate current SPUI/F design assumptions and operation and recommend design and/or operational changes to enhance performance; and (4) evaluate the interchange form selection (pre-design) process and recommend changes where appropriate. The research found no significant difference in the safety aspects of the two interchange types. The SPUI/F generally did not perform as well operationally as the TUDI, with increased SPUI/F delay as the distance between frontage roads increased.

Download or read book Transit Noise and Vibration Impact Assessment written by and published by . This book was released on 1995 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual provides direction for the preparation of noise and vibration sections of environmental documents for mass transportation projects. The manual has been developed in the interest of promoting quality and uniformity in assessments. It is expected to be used by people associated with or affected by the urban transit industry, including Federal Transit Administration (FTA) staff, grant applicants, consultants and the general public. Each of these groups has an interest in noise/vibration assessment, but not all have the need for all the details of the process. Consequently, this manual has been prepared to serve readers with varying levels of technical background and interests. It sets forth the basic concepts, methods and procedures for documenting the extent and severity of noise impacts from transit projects.
Download or read book Gravel Roads written by Ken Skorseth and published by . This book was released on 2000 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
