Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to provide the Montana Department of Transportation (MDT) with information that will be useful in selecting cost effective pavement marking systems. This report begins with a description of available pavement marking technologies, including a discussion of performance parameters of importance and the advantages and disadvantages offered by the various technologies. A review of some of the pertinent studies completed by other states (Pennsylvania, Kansas, Minnesota, Virginia, Wyoming, North Dakota, and Idaho) on their pavement marking programs is subsequently presented. Based on the summary of the states included in this study, pavement markings such as conventional paints are viable in areas where pavement markings do not experience high levels of wear due to traffic or winter maintenance activities. In areas where more durability is required, such as intersections, highways in snowy areas, etc., durable products like epoxy paints or thermoplastics are justified. Since the MDT is able to procure epoxy paint markings for a very reasonable cost, greater use of this durable pavement marking is certainly justified, especially considering the level of wear Montana state highways experience from snowplowing and sanding. MDT investigation of the use of mid-durable paints is warranted due to increased durability and lower cost of these products. In spite of their high cost, extruded thermoplastics and preformed tapes are still viable in areas of high wear, such as intersections and urban streets, according to the results of the studies reviewed in this report.

Available in PDF, EPUB and Kindle. Book excerpt: The Virginia Department of Transportation (VDOT) currently uses snowplowable raised pavement markers (SRPMs) to supplement longitudinal pavement markings on some facilities. SRPMs are much more visible than traditional longitudinal markings under wet, nighttime conditions. SRPMs have been reported to dislodge from pavement, however, which has raised the question as to whether alternative marking materials might be able to replace SRPMs. The purpose of this study was to investigate the visibility performance of longitudinal pavement marking materials currently on the market. The specific objectives of this study were (1) to determine whether or not new pavement marking materials could be used in place of SRPMs; (2) if SRPMs were to be used, to develop guidelines for their installation and maintenance; and (3) to determine the costs and benefits of using SRPMs to the maximum extent possible. No new data on the visibility or durability of pavement marking materials were collected for this study. The study primarily synthesized existing research on the characteristics of different marking materials and then applied information derived from the synthesis to Virginia-specific data to estimate the impacts of using different materials. National practices for installing, inspecting, and maintaining SRPMs were also reviewed. The results of the literature review indicated that SRPMs remain the only marking system that provides sufficient nighttime preview time at high speeds, especially under wet conditions. Further, SRPMs can improve safety in certain situations, but they can also degrade safety in other situations since drivers may travel at higher speeds when the distance they can see down the road at night increases. Proposed guidelines for the installation and maintenance of SRPMs were developed. They recommend that SRPMs be installed on all limited access freeways, on all two-lane roads with an average daily traffic volume above 15,000 vehicles per day, and on all roads with a posted speed limit of 60 mph or greater. Several other situations where SRPMs might be installed based on engineering judgment were also identified. A proposed maintenance schedule that requires inspections every 2 to 3 years was also developed. A conservative economic analysis indicated that the benefits of installing and maintaining SRPMs using the guidelines developed in this study outweighed the costs by more than 80 to 1, based purely on potential safety improvements on road geometries where SRPMs have been shown to improve safety. Further, VDOT can realize cost savings by discontinuing SRPM usage on low-volume facilities and by revising particular SRPM standards.

This book was released on 2012-09-14 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical tools for analyzing, calculating, and reporting availability, reliability, and maintainability metrics Engineers in the telecommunications industry must be able to quantify system reliability and availability metrics for use in service level agreements, system design decisions, and daily operations. Increasing system complexity and software dependence require new, more sophisticated tools for system modeling and metric calculation than those available in the current literature. Telecommunications System Reliability Engineering, Theory, and Practice provides a background in reliability engineering theory as well as detailed sections discussing applications to fiber optic networks (earth station and space segment), microwave networks (long-haul, cellular backhaul and mobile wireless), satellite networks (teleport and VSAT), power systems (generators, commercial power and battery systems), facilities management, and software/firmware.
