Book excerpt: "The FHWA in coordination with AASHTO conducted a study to define a consistent and reliable method to document infrastructure health with a focus on pavements and bridges on the Interstate System, and to develop a framework for tools that can provide FHWA and State DOTs ready access to key information that will allow for better and more complete assessments of infrastructure health nationally. This report summarizes the proceedings of a national meeting entitled, AASHTO/FHWA Workshop on the Highway Infrastructure Health Assessment Study. This workshop provided an opportunity for senior-level State department of transportation (DOT) stakeholders to provide input into national performance measures for pavements and bridges and identify challenges and implementation issues. The results of this Workshop including a summary of discussions related to proposed pavement and bridge condition and health metrics are contained in this report."--Technical report documentation page.

This book was released on 2011 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to define a consistent and reliable method to document infrastructure health with a focus on pavements and bridges on the Interstate System (that can be expanded to the National Highway System) and to develop a framework for tools that can provide FHWA and State DOTs ready access to key information that will allow for better and more complete assessments of infrastructure health nationally. The goal of the proposed work is to evaluate how performance/condition data can be used for corridor and system management, and facilitate analysis of performance measures and system health for a multi-state Interstate highway corridor. Data quality and data collection differences between States are important issues to be addressed. This work will compliment efforts underway (i.e. such as FHWA's Pavement Health Tool initiative, AASHTO's Bridge element inspection manual, and various activities being undertaken by AASHTO's performance management Task Forces, and NCHRP) to develop improved methodologies that could be used as the basis for performance measurement within an infrastructure performance based program. Critical work areas within this project will better support FHWA and AASHTO's role in managing a performance based infrastructure program.

Available in PDF, EPUB and Kindle. Book excerpt: "This report documents the results of a pilot study conducted as part of a project on improving FHWA's ability to assess highway infrastructure health. As part of the pilot study, a section of Interstate 90 through South Dakota, Minnesota, and Wisconsin was evaluated in order to 1) test approaches for categorizing bridge and pavement condition as good/fair/poor that potentially could be used across the country, and 2) provide a proof of concept for a methodology to assess and communicate the overall health of a corridor with respect to bridges and pavements. As a result of the pilot study, it was found that a bridge good/fair/poor methodology can be implemented nationwide today. For pavements, the International Roughness Index can be used today to classify pavement ride quality nationwide. However, additional investigation of other pavement condition metrics is necessary prior to implementation of a holistic pavement indicator that includes distress and structural condition. Also, a conceptual condition and health reporting tool was developed and is presented in the report."--Technical report documentation p.

Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted as part of the Federal Highway Administration (FHWA) Task Order “Improving FHWA’s Ability to Assess Highway Infrastructure Health.” This portion of the study had the objective of developing a next generation pavement performance measure that provides an accurate and repeatable assessment of the functional condition of the roadway. The measure is to combine ride quality, cracking, and rutting or faulting and rely entirely upon data from the Highway Performance Management System (HPMS) database. Over the course of the study, the effort shifted away from a single composite index of ride quality, cracking, and rutting or faulting to using these distresses individually. This report provides recommendations for collecting, processing, reviewing, and storing each of these distresses. Further recommendations are made with regard to assessing pavement condition based upon the stored values.

This book was released on 2013 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This addendum documents the investigation of the rutting bias between field data and the Highway Performance Monitoring System (HPMS)/State Department of Transportation (DOT) pavement management system (PMS) data observed in the pilot study conducted as part of the "Improving FHWA's Ability to Assess Highway Infrastructure Health" project. The objectives of this study were to: 1) investigate the discrepancy between rutting observed from field data collection versus that retrieved from HPMS/State data to determine the cause of the bias, and 2) develop data requirements and an algorithm that can be applied to rutting to produce consistent, high - quality data. A conclusive reason for the South Dakota rutting bias found during the pilot study was identified, but one for the Minnesota data could not be identified. It is possible that the rutting bias for the Minnesota data is the result of several variables, including different gage width, different sensor types, different years of data collection, different drivers, and different vehicle types. Based on the results of this investigation, rutting data requirements such as maximum longitudinal spacing, minimum number of points collected to characterize the transverse profile, gage width, and rutting algorithms are recommended.

Download or read book Federal-aid Highways written by United States. Government Accountability Office and published by . This book was released on 2005 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The federal-aid highway program provides over $25 billion a year to states for highway and bridge projects, often paying 80 percent of these projects' costs. The federal government provides funding for and oversees this program, while states largely choose and manage the projects. Ensuring that states effectively control the cost and schedule performance of these projects is essential to ensuring that federal funds are used efficiently. We reviewed the Federal Highway Administration's (FHWA) approach to improving its federal-aid highway project oversight efforts since we last reported on it in 2002, including (1) FHWA's oversight-related goals and performance measures, (2) FHWA's oversight improvement activities, (3) challenges FHWA faces in improving project oversight, and (4) best practices for project oversight. FHWA has made progress in improving its oversight efforts since 2002, but it lacks a comprehensive approach, including goals and measures that guide its activities; workforce plans that support these goals and measures; and data collection and analysis efforts that help identify problems and transfer lessons learned. FHWA's 2004 performance plan established, for the first time, performance goals and outcome measures to limit cost growth and schedule slippage on projects, but these goals and measures have not been effectively implemented because FHWA has not linked its day-to-day activities or the expectations set for its staff to them, nor is FHWA fully using them to identify problems and target its oversight. FHWA undertook activities in response to concerns raised about the adequacy of its oversight efforts that have both promising elements and limitations. For example, while FHWA now assigns a project oversight manager to each major project (generally projects costing $1 billion or more) and identified skills these managers should possess, it has not yet defined the role of these managers or established agencywide performance expectations for them. While FHWA issued guidance to improve cost estimating and began collecting information on cost increases, it still does not have the capability to track and measure cost growth on projects. Finally, although FHWA received direction to develop a more multidisciplinary workforce to conduct oversight, it has not fully incorporated this direction into its recruiting and training efforts. FHWA faces challenges to improving its oversight that are in large part rooted in the structure of the federal-aid highway program and in FHWA's organization and culture. As such, they may be difficult to surmount. For example, because the program does not link funding to states with the accomplishment of performance goals and outcome measures, it may be difficult for FHWA to define the role and purpose of its oversight. Also, FHWA's decentralized organization makes it difficult to achieve a consistent organizational vision. Human capital challenges affecting much of the federal government have affected FHWA, particularly in its need to transform its workforce to meet its evolving oversight mission. FHWA faces an increased oversight workload in the years ahead as the number of major projects grows and if provisions Congress is considering to increase FHWA's responsibilities become law. Questions exist about FHWA's ability to effectively absorb these new responsibilities, overcome underlying challenges, and improve its oversight. We identified selected best practices that could help FHWA develop a framework for a comprehensive approach to project oversight. These include establishing measurable goals to objectively and quantifiably assess progress, making oversight managers accountable for the effective implementation of these goals, providing professional training, and collecting and transferring lessons learned.

This book was released on 2001 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Federal and state governments have played a vital role in the nation economy by facilitating the movement of people and goods through significant investments in highways. At the federal level, the Department of Transportation (DOT) Federal Highway Administration (FHWA) uses a computer model known as the Highway Economic Requirements System (HERS) to estimate the future investment required to maintain and improve the nation highways. DOT reports the results of this analysis to the Congress on a biennial basis. However, state governments make a large number of highway infrastructure investment decisions. States currently use a variety of analytic tools to make these decisions. Interest in using HERS at the state level has grown. Two states Indiana and Oregon are already using customized versions of the model, and in December 2000, FHWA began a pilot project to test its state-level version of HERS, called HERS-ST, with interested states.

Available in PDF, EPUB and Kindle. Book excerpt: In an increasingly globalised world, despite reductions in costs and time, transportation has become even more important as a facilitator of economic and human interaction; this is reflected in technical advances in transportation systems, increasing interest in how transportation interacts with society and the need to provide novel approaches to understanding its impacts. This has become particularly acute with the impact that Covid-19 has had on transportation across the world, at local, national and international levels. Encyclopedia of Transportation, Seven Volume Set - containing almost 600 articles - brings a cross-cutting and integrated approach to all aspects of transportation from a variety of interdisciplinary fields including engineering, operations research, economics, geography and sociology in order to understand the changes taking place. Emphasising the interaction between these different aspects of research, it offers new solutions to modern-day problems related to transportation. Each of its nine sections is based around familiar themes, but brings together the views of experts from different disciplinary perspectives. Each section is edited by a subject expert who has commissioned articles from a range of authors representing different disciplines, different parts of the world and different social perspectives. The nine sections are structured around the following themes: Transport Modes; Freight Transport and Logistics; Transport Safety and Security; Transport Economics; Traffic Management; Transport Modelling and Data Management; Transport Policy and Planning; Transport Psychology; Sustainability and Health Issues in Transportation. Some articles provide a technical introduction to a topic whilst others provide a bridge between topics or a more future-oriented view of new research areas or challenges. The end result is a reference work that offers researchers and practitioners new approaches, new ways of thinking and novel solutions to problems. All-encompassing and expertly authored, this outstanding reference work will be essential reading for all students and researchers interested in transportation and its global impact in what is a very uncertain world.

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.
