This report provides guidance on selecting the appropriate barrier performance level for the installation of longitudinal barriers. The report presents performance-level selection guidelines to help designers determine the most appropriate guardrail test level for any route. Further, site-specific guidelines not only identify what guardrail test level should be incorporated but also can be used to determine when guardrail use is not cost beneficial. Supplemental procedures for identifying appropriate guardrail test levels have also been developed. These procedures expand the applicability of the guardrail selection guidelines to many unusual hazards that cannot be included in development of general procedures. The report will be of particular interest to designers with responsibility for designing roadside safety features.

This report contains the findings of research performed to quantify the safety and operational impacts of design element trade-offs and their associated risks. The report details the research performed and includes specific recommended crash prediction models and Accident Modification Factors (AMFs) for shoulder width and median width on rural four-lane roads. Thus, the report will be of immediate interest to engineers in state highway agencies responsible for geometric design and traffic operations and safety.

This report presents proposed guidelines for dowel alignment in concrete pavements. These guidelines deal with the effects of dowel misalignment on performance and the measures for reducing misalignment and its adverse effect. The report will guide pavement and construction engineers in considering dowel misalignment in pavement design and identifying measures for reducing misalignment during construction or for dealing with misaligned dowels. The information contained in the report will be of immediate interest to state engineers and others concerned with concrete pavement design and construction.

Adhesive Anchors in Concrete Under Sustained Loading Conditions
Author: Cook, Ronald A | Size: 9.67 MB | Format:PDF | Quality:Original preprint | Publisher: Transportation Research Board | Year: 2009 | pages: 142 | ISBN: 9780309117883
This report presents a test method recommended to determine an adhesive anchor's ability to resist sustained tensile loads. The report will be of immediate interest to public- and private-sector engineers with responsibility for the specification and use of adhesive anchor systems. The recommended test method, which is presented in Appendix A in the form of a draft AASHTO standard, is under consideration for possible adoption by the AASHTO Highway Subcommittee on Materials.

Procedures Guide for Right-of-Way Cost Estimation and Cost Management
Author: Anderson, Stuart D | Size: 6.97 MB | Format:PDF | Quality:Original preprint | Publisher: Transportation Research Board | Year: 2009 | pages: 226 | ISBN: 9780309117807
This procedures guide presents practical and effective approaches for developing right-of-way (ROW) cost estimates and for then tracking and managing ROW cost during all phases of project development, including planning, programming, and preliminary and final design. It is a resource for managers, practitioners, and decisionmakers interested in developing and managing realistic and accurate estimates of ROW cost from the earliest ROW cost estimate made during planning through to the management of ROW acquisition cost during final design.

This report presents a recommended process for determining the type of concrete pavement texture that should be used for a specific highway project. The process considers the effects of texture type on friction and noise characteristics. The report will guide pavement and construction engineers in identifying and specifying textures for concrete pavements that will provide adequate surface characteristics. The information contained in the report will be of immediate interest to state engineers and others concerned with concrete pavement design and construction.

Guidance for the Design and Application of Shoulder and Centerline Rumble Strips
Author: Torbic, Darren John | Size: 7.30 MB | Format:PDF | Quality:Original preprint | Publisher: Transportation Research Board | Year: 2009 | pages: 181 | ISBN: 9780309117999
This report provides guidance for the design and application of shoulder and centerline rumble strips as an effective crash reduction measure, while minimizing adverse effects for motorcyclists, bicyclists, and nearby residents. Using the results of previous studies and the research conducted under this project, safety effectiveness estimates were developed for shoulder rumble strips on rural freeways and rural two-lane roads and for centerline rumble strips on rural and urban two-lane roads. The report will be of particular interest to safety practitioners with responsibility for roadway design.

This report presents a business plan for the development of Transportation Knowledge Networks in the United States. The project builds on a number of previous Transportation Research Board activities aimed at improving access to information for transportation professionals. If successfully implemented, a decentralized, managed network of information centers will help link users to the information they need, when they need it. This report will be of interest to all transportation practitioners, managers, and executives who need more effective and efficient ways to navigate the vast pool of information resources available to them.
