TRB Webinar: Principles and Practices of Quieter Pavements

Designing and constructing quieter pavements can be accomplished using the same materials and techniques commonly used today. However, there remain knowledge gaps in how to do so effectively, and without compromising other important characteristics including safety, durability, and cost. This webinar will introduce the principles and practices of designing & constructing quieter pavements. It is intended to educate noise practitioners on the fundamentals of pavements, and to educate pavement practitioners on the fundamentals of noise.

At the conclusion of this workshop, the audience members should be able to:
• Discuss some of the fundamentals of sound and texture.
• Describe research and policy directions related to the use of quieter pavements.
• Illustrate how quieter pavements are measured and interpreted.
• Categorize the mechanisms that lead to tire-pavement noise.
• Develop an approach for incorporating quieter pavement design and construction principles into their current practices.
• Evaluate the role of a quieter pavement among other needs including safety, durability, and cost effectiveness.

Panelists for this webinar include:
Robert Rasmussen, The Transtec Group, Inc.
Paul Donavan, Illingworth & Rodkin, Inc.
Judy Rochat, USDOT Volpe Center

TRB Webinar: Entering and Managing Project Records in the Research in Progress (RiP) Database

TRB will be conducting a web seminar or “webinar” on August 11, 2011, from 2:00 PM to 3:30 PM EDT that will enable individuals to become familiar with entering and managing project records in the Research in Progress (RiP) Database.

The Transportation Research Board's RiP website is a leading tool for transportation professionals to stay updated on the status of world-wide transportation research projects. The website contains the Research in Progress (RiP) Database and a data-entry system to allow users to add, modify, and delete information on their current research projects. The RiP database contains more than 12,000 current or recently completed transportation research projects. Most of the RiP records are projects funded by federal and state departments of transportation. University transportation research is also included. The RiP Database serves as a clearinghouse of University Transportation Centers’ ongoing research. International research projects from the TRIP file of the International Transport Research Documentation Database are included in the RiP database, and the Transportation Association of Canada supplies records from its Canadian Surface Transportation Research Database.

At the end of this training webinar users will know how to:

• Submit a new project using the form on the RiP web site;
• Upload a batch of project records;
• Locate records from your organization;
• Modify or delete an existing project record from your organization;
• Submit or modify information on a person, e.g. project manager;
• Submit or modify information on an organization.

Trial access to the National Technical Reports Library (NTRL)

I have arraigned for us to have a trial subscription to the National Technical Reports Library (NTRL). NTRL provides easy access to federally funded technical reports in all subject areas “directly and seamlessly to the user's desktop.” A description of the database can be found here -

You can access the database from any LTRC and DOTD networked computer at and linked from the Library’s web site, through May 23, 2011. Please try it out and let me know what you think. How useful do you think this would be to your work and research?

This trial was offered by the National Technical Information Service (NTIS) as an opportunity to participate in the evaluation of the NTRL Beta platform. If you have to opportunity to try out NTRL, they have asked that you give them some feedback at

Enjoy! And don’t forget to let me know what you think.

The TRIS and ITRD Databases are now TRID!

Hi all,
If you haven’t already heard, the TRIS database is no more. In its place, we now have TRID which combines the resources from TRIS with RiP (Research in Progress) and ITRD (International Transport Research Documentation) from the OECD's Joint Transport Research Centre. This will give us access to many more resources and open up our research to include what is going on outside of the US.

If you have any questions or comments about TRID please let me know. If don’t know the answer I will certainly find out for you, and I will pass on any comments you have.

Here is the announcement I received from TRB:

The Transportation Research Board and the Joint Transport Research Centre of the International Transport Forum and OECD are pleased to announce that TRID - the TRIS and ITRD Database was launched at TRB’s 90th Annual Meeting on 23 January, 2011.

TRID offers:
  • One database to locate research from around the world
  • Multilingual database with records in English, German, French or Spanish
  • More than 900,000 records of published or on-going research
  • Indexing from the Transportation Research Thesaurus or the multilingual ITRD thesaurus
  • Free access to the public at TRB’s website

TRID offers flexibility in searching. It includes both simple and advanced query screens and offers browsing of recent publications by mode. When available, links are provided to the full text of the document or to direct ordering information. TRID allows users to print, download, directly e-mail, or share search results and also offers users the ability to subscribe to RSS feeds to receive notification of the latest publications on a specific topic. The TRID website includes “Hot Topic” searches on subjects of current interest.

TRID is available at

The TRIS and TRISworld databases will be available through 30 January, 2011. On 31 January the URLs for TRIS and TRISworld will permanently redirect to TRID. TRID is very similar to TRIS and TRISworld and thus we expect that users will easily transition to using TRID.
