How to Develop a Pedestrian Safety Action Plan 2006 - This guide from FHWA will help state and local officials know where to begin to address pedestrian safety issues by providing a framework to develop and implement a pedestrian safety action plan tailored to their specific problems and needs. It is also intended to assist agencies in further enhancing their existing pedestrian safety programs and activities, including identifying safety problems, analyzing information, and selecting optimal solutions.
Symposium on Geometric Design - This link provides presentations given at TRB's 3rd International Symposium on Highway Geometric Design, held in Chicago, IL, in June 2005.
New AASHTO Design Publications 2005 (2Mb, PowerPoint) - This presentation provides an overview of changes made in the new Green Book, as well as other new publications released in 2005.
Style Manual for AASHTO Publications (1.4Mb, pdf) - This document was created to assist the many committee volunteers, vendors, and consultants in editing, formatting, and preparing text for AASHTO publications.
SCOD Technical Committee Work Plans 2005 (85k pdf) - This report contains the work plans for the Technical Committees that report to the Subcommittee on Design. These work plans outline the activities planned for the coming year, as well as goals for the next 5-year period.
Bicycle Railing Height Report (1.1Mb pdf) 2004 - This NCHRP research report focused on appropriate bridge railing heights for bicyclists.
Highway Loading Information (1.1Mb pdf) 2002 - Excerpted from the 2002 Standard Specifications on Highway Bridges, 17th Edition, this information on loading provides details on typical dead and live loads used in design work, including standard H and HS truck loadings.
Project Cost Estimating: A Synthesis of Highway Practice (782Kb pdf) 2003 - This report, developed through an NCHRP project and based on a survey of all 50 states, provides information on the state-of-the-practice of project cost estimating within State DOTs. Areas investigated include: estimating practices; methods for resolving discrepancies between DOT estimates and bid prices; problems that remain largely unresolved across the country; and practices that produce estimates within a +/- 5% variability between the DOT estimate and contractor bid.
Interim Guide, Geometric Design for Transit Vehicles on Highways and Streets, July 2002 - Many agencies at the state, county, and municipal level are required to plan, design, and/or modify highways and streets to accommodate public transportation vehicles or facilities. Currently, there is no single publication to which an agency can refer for highway design guidance to accommodate transit services and facilities. This interim document is intended to function as a comprehensive reference of current practice in geometric design applications for transit facilities on urban highways and streets.
A follow-on project, TCRP D-09, will develop a handbook that includes comprehensive geometric design guidelines for accommodating transit vehicles and facilities, and guidelines for selecting appropriate transit facilities to accommodate current and future transit demand. This project is scheduled for completion in December 2004.
Preconstruction Engineering Management Survey Results (940Kb pdf) 2003 - This report summarizes a survey that was conducted of the State Departments of Transportation in Spring 2003 on the state of preconstruction engineering management. The survey focused on seven distinct areas, including organizational structure, project management practices, preconstruction scheduling and authority, computer system software, streamlining issues, the use of consultants, and performance measures. Detailed responses from each state are provided in an accompanying spreadsheet: Individual State Responses (169Kb Excel).

Center for Environmental Excellence by AASHTO - This AASHTO web site provides current environmental information for transportation professionals.
Domestic Scan Tour on Environmental Commitment Implementation - This FHWA web site houses the report from a 2002 US Scan which reviewed successful State processes, procedures, and methodologies used in fulfilling environmental commitments made in the transportation project development process and environmental permits.
NCHRP Report 480, A Guide to Best Practices for Achieving Context Sensitive Solutions - This report demonstrates how state departments of transportation (DOTs) and other transportation agencies can incorporate context sensitivity into their transportation project development work.
Design-Build References - This is a link to the References page of the Design-Build Task Force's web site, including their "Current Design-Build Practices for Transportation Projects" report, which is a compilation of the design-build experiences of State DOTs and other public agencies dealing with transportation infrastructure.
