Download or read book Implementing the Rule on Work Zone Safety and Mobility written by United States Department of Transportation and published by CreateSpace. This book was released on 2015-02-23 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: In September 2004, the Federal Highway Administration (FHWA) published updates to the work zone regulations at 23 CFR 630 Subpart J. The updated rule is referred to as the Work Zone Safety and Mobility Rule (Rule) and applies to all State and local governments that received Federal-aid highway funding. Transportation agencies are required to comply with the provisions of the Rule by October 12, 2007. The changes made to the regulations broaden the former rule to better address the work zone issues of today and the future. Growing congestion on many roads, and an increasing need to perform rehabilitation and reconstruction work on existing roads already carrying traffic, are some of the issues that have lead to additional, more complex challenges to maintaining work zone safety and mobility. To help address these issues, the Rule provides a decision-making framework that facilitates comprehensive consideration of the broader safety and mobility impacts of work zones across project development stages, and the adoption of additional strategies that help manage these impacts during project implementation. The Rule requires agencies to develop an agency-level work zone safety and mobility policy to support systematic consideration and management of work zone impacts across all stages of project development. Based on the policy, agencies will develop standard processes and procedures to support implementation of the policy. The third primary element of the Rule calls for the development of project-level procedures to address the work zone impacts of individual projects. To help transportation agencies understand and implement the provisions of the Rule, FHWA has been developing four guidance documents. This Guide is the main Rule Implementation Guide and provides a general overview of the Rule and overarching guidance for implementing the provisions of the Rule. This document includes guidelines and sample approaches, examples from transportation agencies using practices that relate to the Rule, and sources for more information. While this Guide covers aspects of the Rule, it also contains information that can be useful to agencies in all of their efforts to improve safety and mobility in and around work zones, and thereby support effective operations and management of our transportation system.
Download or read book Work Zone Public Information and Outreach Strategies written by United States Department of Transportation and published by CreateSpace. This book was released on 2015-02-23 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document is meant to help transportation agencies plan and implement effective public information and outreach campaigns for work zones. The focus of this document is not on project selection and design, but on the travel impacts of a work zone – such as lane closings, new traffic patterns, and traffic delay – and available travel alternatives (e.g., different routes and travel modes). This document provides information and strategies for developing public information and outreach campaigns for specific work zones, rather than general work zone education and safety campaigns. It is primarily designed for personnel in transportation agencies responsible for planning and operating highway work zones and those responsible for public relations and public information. It will also be of interest to transportation policy makers, work zone contractors, consultants, public relations firms, and emergency responders. This document also provides support to agencies in their efforts to implement the recently updated work zone regulations. In September 2004, the Federal Highway Administration (FHWA) published updates to the work zone regulations at 23 CFR 630 Subpart J. The updated rule addresses the use of public information and outreach as a work zone management tool. The updated rule is referred to as the Work Zone Safety and Mobility Rule (Rule) and applies to all State and local governments that receive Federal-aid highway funding. Transportation agencies are required to comply with the provisions of the Rule by October 12, 2007. The changes made to the regulations broaden the former rule to better address the work zone issues of today and the future. Growing congestion on many roads, and an increasing need to perform rehabilitation and reconstruction work on existing roads already carrying traffic, are some of the issues that have lead to additional, more complex challenges to maintaining work zone safety and mobility. To help address these issues, the Rule provides a decision-making framework that facilitates comprehensive consideration of the broader safety and mobility impacts of work zones across project development stages, and the adoption of additional strategies that help manage these impacts during project implementation. The Rule requires agencies to develop an agency-level work zone safety and mobility policy to support systematic consideration and management of work zone impacts across all stages of project development. Based on the policy, agencies will develop processes and procedures to support implementation of the policy. The third primary element of the Rule calls for the development of project-level procedures to address the work zone impacts of individual projects. This includes requirements for identifying significant projects and developing and implementing transportation management plans (TMPs) for all projects. For significant projects, the TMP must include public information and outreach strategies to inform those affected by the project of expected work zone impacts and changing conditions. This document is the second of four guidance documents on the Rule and contains guidance, as well as many examples of work zone public information and outreach campaigns used by transportation agencies.
Download or read book Developing and Implementing Transportation Management Plans for Work Zones written by United States Department of Transportation and published by CreateSpace. This book was released on 2015-02-23 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Guide is designed to help transportation agencies develop and implement transportation management plans (TMPs). A TMP lays out a set of coordinated transportation management strategies and describes how they will be used to manage the work zone impacts of a road project. The scope, content, and level of detail of a TMP may vary based on an agency's work zone policy and the anticipated work zone impacts of the project. The intended audience for this Guide is the persons responsible for developing TMPs. Depending on the agency's processes and procedures, this may be agency personnel and/ or contractors. Persons responsible for TMP-related policy/procedure development and revision, implementation, review, approval, and assessment will also benefit from this Guide. This document also provides support to agencies in their efforts to implement the recently updated work zone regulations. In September 2004, the Federal Highway Administration (FHWA) published updates to the work zone regulations at 23 CFR 630 Subpart J. The updated rule is referred to as the Work Zone Safety and Mobility Rule (Rule) and applies to all State and local governments that receive Federal-aid highway funding.

Download or read book Improving Traffic Control Effectiveness in Complex Work Zones written by Gerald L. Ullman and published by . This book was released on 2003 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information from driver studies performed during the first year of the project identified several features and conditions that created confusion and anxiety in traversing the work zone. Many of these conditions represented deficiencies in the work zone traffic control from the standpoint of positive guidance principles. This report describes the efforts to tailor the application of positive guidance procedures to work zone traffic control installations reviews. Four key steps, hazard visibility assessment, expectancy violation determination, information load analysis, and information needs specification, are described in the context of traffic control at potentially complex work zones. A methodology is presented for applying these steps in a field review process to be performed as part of the work zone traffic control installation process.
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.

Download or read book A Comprehensive Discrete Choice Analysis of Injury Severity in Roadway Work Zone Crashes written by Mohamed Osman and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Work zones are critical parts of the transportation infrastructure renewal process consisting of rehabilitation of roadways, maintenance, and utility work. Given the specific nature of a work zone (complex arrangements of traffic control devices and signs, narrow lanes, duration) a number of crashes occur with varying severities involving different vehicle sizes. This dissertation proposes a comprehensive discrete choice analysis of injury severity of crashes in work zones on both the crash and occupant levels, in roadway work zones through a comprehensive set of discrete choice econometric frameworks. Robust discrete choice modeling structures are introduced and applied in the field of work zone safety. This dissertation contains three (3) studies representing the empirical analysis conducted to address the following research questions:1. What factors may contribute to the injury severity levels of large-truck crashes in work zones? And what are the robust analytical methods to recognize such factors?2. How do specific work zone configurations affect factors contributing to the levels of injury severity of work zone crashes?3. How does the specific work zone-component-area where a crash has occurred affect factors contributing to the injury severity levels of work zone crashes?The first study investigates the causal factors contributing to injury severity of large truck crashes in work zones. The second study investigates the causal factors contributing to the injury severity of passenger-car occupants for crashes occurring in different work zone configurations (lane closure, lane shift/crossover, shoulder/median, intermittent, and other). The third study investigates the causal factors contributing to driver & rsquo;s injury severity in the different work zone component-areas (advance-warning, transition, activity, and termination areas). The first study compares a comprehensive set of discrete choice modeling structures; Multinomial Logit (MNL) model, Nested Logit (NL) model, Ordered Logit (ORL) model and Generalized Ordered Response Logit (GORL) model. The second and third studies developed the Mixed Generalized Ordered Response Probit (MGORP) modeling framework to conduct the proposed analysis to answer the second and third research questions. The empirical analysis was conducted using work zone crash database in 10 years of the Highway Safety Information System (HSIS).
