This book was released on 2006 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an annual pavement marking program of approximately $2 million and another $750 thousand invested in maintenance of durable markings each year, the Iowa DOT is seeking every opportunity to provide all-year markings staying in acceptable condition under all weather conditions. The goal of this study is to analyze existing pavement marking practices and to develop a prototype Pavement Marking Management System (PMMS). This report documents the first two phases of a three-phase research project. Phase I includes an overview of the Iowa DOT's existing practices and a literature review regarding pavement marking practices in other states. Based on this information, a work plan was developed for Phases II and III of this study. Phase II organized the key components necessary to develop a prototype PMMS for the Iowa DOT. The two primary components are (1) performance/life cycle curves for pavement marking products, and (2) an application matrix tailored to the pavement marking products and roadway and environmental conditions faced by the Iowa DOT. Both components will continue to be refined and tailored to Iowa materials and conditions as more performance data becomes available.

This book was released on 2011 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report discusses the use of image processing techniques to assess pavement marking quality. Images of pavement markings are processed using a number of operations. Image segmentation is the process of assigning the set of image pixels to regions having common characteristics. The proposed system tries to segment images of white or yellow pavement markings into foreground (marking) and background (pavement) parts. The images are then processed to determine pavement marking presence in an objective and consistent manner. The resulting assessment is critical to the implementation and development of a pavement marking management system and quality control/assurance processes.

This book was released on 2008 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document summarizes the development of a scalable, reliable, and practical process for viewing, querying, understanding, and making consistent, objective, and cost effective decisions regarding pavement marking needs, durability, and quality. The research team developed a Web-based pavement marking management system through the development environment of Microsoft Visual Studio 2005 ASP.NET in conjunction with ESRI's ArcGIS Sever Enterprise 9.2 SP4 functionalities to manage and produce the GIS map resources. The web site hosting itself was done on a Windows based server operating Internet Information Services (IIS). The resulting web based mapping tool provides Mn/DOT staff the ability to map and query pavement marking retroreflectivity information and serves as a significant resource to both district and central office staff in developing short and long-term pavement marking plans.
Download or read book Pavement Marking Performance Analysis written by and published by . This book was released on 2009 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research evaluated pavement marking performance and developed useful degradation models for thermoplastic and paint pavement markings which can help North Carolina meet the pending FHWA minimum retroreflectivity requirements. The impacts of several important factors (such as lateral location, directionality, region, and pavement roughness) on pavement marking retroreflectivity were evaluated. With two large datasets in hand, the authors determined whether these factors had significant impacts on marking retroreflectivity. Image processing techniques were used to analyze pavement marking surface glass bead density. The authors were able to explain why paint marking retroreflectivity values degraded over time by evaluating the impact of bead density on paint marking retroreflectivity. The research reviewed existing marking retroreflectivity degradation models and developed useful new models for both thermoplastic and paint pavement markings in North Carolina. The research presented a transportation asset management system framework for estimating the current and future condition of pavement markings. The research outcomes enable the North Carolina Department of Transportation to have a better understanding of thermoplastic and paint pavement marking performance, which can lead to cost saving by maximizing pavement marking service lifecycles.

Available in PDF, EPUB and Kindle. Book excerpt: Pavement markings guide and safeguard road users, and maintaining adequate retroreflectivity is crucial for ensuring road safety. Accurate prediction of retroreflectivity and determination of service life are essential for optimizing maintenance efforts. As the Wyoming Department of Transportation (WYDOT) performs routine application of pavement markings, there is a pressing need for a comprehensive management program to ensure their cost-effective management. So, this thesis focuses on enhancing pavement marking management in Wyoming by investigating factors influencing retroreflectivity, developing predictive models for degradation over time, and establishing a comprehensive Pavement Marking Management Plan (PMMP) that incorporates the principles of the Transportation Asset Management Plan. Binary Logistic Regression models were developed to determine the contributing factors affecting pavement marking retroreflectivity. The findings of this study indicate that factors such as the degree of curvature of horizontal curves, location (rural or urban), material type, pavement marking color, and line position significantly affect pavement marking retroreflectivity. Pavement marking degradation models were developed by using Bayesian Ordered Logit Model. The degradation models provide valuable insights into the deterioration process of pavement markings over time and can assist highway agencies in prioritizing maintenance efforts. The proposed Pavement Marking Management Plan (PMMP) template also integrates Pavement Marking Management Systems of several state DOTs and Transportation Asset Management principles, providing project selection, budgeting, procurement, and contracting strategies. The PMMP also addresses advanced vehicle technologies, advocating for wider longitudinal pavement markings to accommodate machine vision systems.

This book was released on 1993 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1992, the Iowa DOT Pavement Management Information System (PMIS) was designed and implemented. The PMIS replaced the Iowa Pavement Management System (IPMS) that had been implemented in 1979. Based upon the interviews that were conducted with many Iowa DOT Offices so that "User Requirements" for the system could be determined, this phase of the PMIS is the "first building block" in providing better and easier access to the data that is used in the calculation of PCRs (Pavement Condition Ratings). The PCRs are used as a guide by the Office of Program Management to determine which sections of highways should be included in the five-year "Iowa Transportation Improvement Program".

Download or read book Evaluation of Pavement Markings on Low Volume Rural Roadways in Iowa written by Keith Knapp and published by . This book was released on 2015 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many rural roadways in Iowa have centerline and/or edgeline pavement markings. The current Manual on Uniform Traffic Control Devices (MUTCD), however, requires centerline and/or edgeline pavement markings only along streets and roadways with traffic volumes much greater than 400 vehicles per day (the volume-based definition of a low-volume roadway in the MUTCD). This project was initiated to gather and summarize information about the state of practice related to the installation and maintenance of pavement markings along low-volume rural roadways in Iowa. Additional information was also collected to provide more guidance in the pavement-marking decision-making process. The tasks completed include an examination and summary of past research, the collection of legal input related to the use of pavement markings in Iowa, and a survey of Iowa county engineers that focused on their current pavement-marking practices. A basic safety benefit-cost evaluation of pavementmarking applications was also performed. Overall, the literature on the effectiveness of pavement markings and their safety impacts is limited. A number of studies have been completed with varying levels of robustness and reliability in their results. The Highway Safety Manual includes crash modification factors for the installation of centerline markings that it indicates should be used with caution, and one for the installation of edgeline and centerline markings that equates to a 24 percent total serious and minor-injury crash reduction. A more recent study from Louisiana also found a 15 percent reduction in total crashes after the addition of edgelines. The legal input acquired as part of this project was generally common knowledge. It indicated that once a traffic control device has been installed, the jurisdiction must properly and adequately maintain it. The survey completed found that, of the great majority of the respondents (97 percent), painted centerline/no passing zones and edgelines on at least some of their paved low-volume rural roadways. A much smaller percentage took this approach, or just painted centerlines/no passing zones, along their seal-coated roadways. The basic cost-benefit evaluation found that the percentage of crash reduction needed from pavement markings to make them beneficial was very low (i.e., 5.1 percent, at most). Overall, it was concluded that pavement markings are widely used in Iowa along low-volume paved roadways and sometimes seal-coated roadways. In addition, there is a safety benefit to the installation of pavement markings. but the research into that impact is limited, particularly along low-volume roadways. It is recommended that further analysis be completed on potential pavement-marking safety impacts, that a pavement-marking database be developed, and that a committee be initiated to help develop policies related to pavement-marking removal.
