This book was released on 2015-02-27 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This primer has been developed to assist agencies in establishing and monitoring a useful set of work zone safety and mobility performance measures. Work zone performance measures are metrics that help to quantify how work zones impact travelers, residents, businesses and workers. Work zone performance measures help agencies improve their understanding of how their decisions during planning, design, and construction affect work zone safety and mobility, and thus can help improve how they make decisions for future work zones. The primer describes possible work zone performance measures, and provides guidance to help agencies select and implement measures that make sense for their own work zone programs. The primer outlines the methods and technologies that are available to gather data to monitor the various possible measures and procedures for calculating specific performance measures from different types of work zone traffic monitoring data. The primer also discusses the use of measures across multiple projects to assess an agency's overall efforts and outcomes against its policies and goals.

This book was released on 2015-02-25 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current Federal Regulations (23 CFR 630 Subpart J) encourage States to collect and analyze both safety and mobility data to support the initiation and enhancement of agency-level processes and procedures addressing work zone impacts. The purpose of this guidance document is to provide practitioners with the skills to identify current data sources (both existing data and data collected specifically for the work zone) for use in work zone performance measurement, as well as potential data sources that could be useful to work zone performance measurement in the near future. This document is also intended to assist practitioners in determining how to select and compute useful work zone performance measures, given the data sources available to them. For both current and potential data sources, guidance is presented on the viability of each source for work zone performance measurement, as well as on possibly leveraging opportunities to maximize the value of data collection and extraction efforts. In addition to information about data sources and opportunities, guidance is provided regarding work zone performance measures that the various data sources can support. Where appropriate, examples are provided as to how data assessment, collection, application, and interpretation can be accomplished. In this way, document users can obtain an overall perspective.

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 Impacts Assessment written by United States Department of Transportation and published by CreateSpace. This book was released on 2015-02-23 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Guide is designed to help transportation agencies develop and/or update their own procedures for assessing and managing the work zone impacts of their road projects throughout the different program delivery stages. Understanding work zone impacts is critical to developing effective work zone transportation management plans (TMPs) that provide for safety, mobility, and quality in maintaining, rehabilitating, and rebuilding the nation's highways. The primary intended audience for this Guide is transportation agency staff, including technical staff (planners, designers, construction/traffic engineers, highway/safety engineers, etc.); management and executive-level staff responsible for setting policy and program direction; field staff responsible for building projects and managing work zones; and staff responsible for assessing performance in these areas. This document also provides support to agencies in their efforts to implement the recently updated work zone regulations. In September 2004, the 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. 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. 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. These include procedures that address work zone impacts assessment, work zone data, work zone training, and process reviews. The Rule also calls for the development of project-level procedures to help agencies assess and manage the work zone impacts of individual projects. While the Rule does not require a specific work zone impacts assessment process/procedure, it recommends that agencies develop and implement systematic procedures to assess work zone impacts in project development, and to manage safety and mobility during project implementation. This document is the last of four guidance documents developed on the Rule, and provides a general approach for conducting work zone impacts assessment and management, as well as many examples of the approaches currently being used by transportation agencies.

Download or read book Work Zone Performance Measures Pilot Test written by United States Department of Transportation and published by CreateSpace. This book was released on 2015-02-27 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently, a well-defined and validated set of metrics to use in monitoring work zone performance do not exist. This pilot test was conducted to assist state DOTs in identifying what work zone performance measures can and should be targeted, what data they will need to collect to compute those measures, and what methods exist to obtain that data. Work zone activity and traffic data from five work zone projects were gathered and analyzed. Multiple data sources and collection methods were examined and utilized to the extent available at each project. These sources were field crew personnel manually documenting queue presence, length, and duration; traffic surveillance data from a transportation management center or from portable work zone ITS; and third-party probe vehicle data (in this test, large truck speed data obtained via the FHWA Office of Freight Management). The results of the pilot test indicate that manual documentation of queuing by field personnel, and the use of permanent or portable traffic sensor data can be used effectively to measure work zone impacts, given that information as to the time and location of work activities is known. Probe vehicle data is also believed to be a viable source of data, but sample size issues did limit is applicability in this pilot test. Average and maximum queue lengths and duration, duration of queues exceeding pre-determined thresholds, vehicle exposure to queues, and vehicle delays when queues are present were among the several performance measures tested and demonstrated as viable indicators of work zone mobility impacts. A number of lessons learned through this pilot test effort are also included in the report.
