Pavement Marking Performance Analysis by Anonim Pdf

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.

Durability and Retro-Reflectivity of Pavement Markings (Synthesis Study) by Yi Jiang Pdf

Waterborne paints are used to paint pavement markings (edgelines and centerlines) to provide guidance for motorists. The painted markings need to be repainted periodically as their retro-reflectivity deteriorates. The Indiana Department of Transportation (INDOT) repaints pavement markings at least annually. INDOT engineers would like to determine the feasibility of extending the time intervals of repainting pavement markings on at least some types of roadways. The purpose of this synthesis study is to accomplish the following: (1) to locate and assemble documented information on pavement marking durability; (2) to learn what criteria have been used in other states in measuring retro-reflectivity and scheduling pavement marking painting; (3) to determine the necessity of conducting full scale study on INDOT pavement markings; (4) to identify the type and cost of equipment required for retro-reflectivity measurements and conditions of operation of the equipment; (5) to organize, evaluate, and document the useful information that is acquired; and (6) to provide recommendations based on the evaluated information. This report presents the findings of the synthesis study on various pavement marking materials. It was found in this study that many state highway agencies have evaluated several types of pavement marking materials. The evaluation results include performance, cost, service life, and retro-reflectivity measuring equipment of marking materials. However, the results could vary from different sates. The information gathered through this study will provide INDOT engineers the state-of-practice of pavement marking materials in this country.

Advanced Deep Learning Strategies for the Analysis of Remote Sensing Images by Yakoub Bazi,Edoardo Pasolli Pdf

The rapid growth of the world population has resulted in an exponential expansion of both urban and agricultural areas. Identifying and managing such earthly changes in an automatic way poses a worth-addressing challenge, in which remote sensing technology can have a fundamental role to answer—at least partially—such demands. The recent advent of cutting-edge processing facilities has fostered the adoption of deep learning architectures owing to their generalization capabilities. In this respect, it seems evident that the pace of deep learning in the remote sensing domain remains somewhat lagging behind that of its computer vision counterpart. This is due to the scarce availability of ground truth information in comparison with other computer vision domains. In this book, we aim at advancing the state of the art in linking deep learning methodologies with remote sensing image processing by collecting 20 contributions from different worldwide scientists and laboratories. The book presents a wide range of methodological advancements in the deep learning field that come with different applications in the remote sensing landscape such as wildfire and postdisaster damage detection, urban forest mapping, vine disease and pavement marking detection, desert road mapping, road and building outline extraction, vehicle and vessel detection, water identification, and text-to-image matching.
