Welcome to the new site! There were a lot of upgrades and changes behind the scenes, including a new hosting company. The wiki is up again! The biggest change you will see is in the forums with the new Agora software.
There were some problems in the move to the new site. A major crash occurred while transferring the forum posts to the new site. The crash, combined with schedule concerns, means that information posted in May and early June is lost. The crash also wiped registrations during this period. Recovering this information would have required more administration time and resulted in increasing site down time. This was a difficult decision, but it really was time to get the site up and running again.
If your member registration was lost, please re-register. If you encounter problems, please email me at This e-mail address is being protected from spambots. You need JavaScript enabled to view it .
Thank you for your patience during this transition.
After weeks of downtime, the site is now back online with just basic features. Work to recover the site is ongoing and will probably take another week. Thank you for your patience.

Now available for download, these slides cover lessons learned in two open source research community development efforts in the traffic modeling and simulation domain: TRANSIMS and NGSIM. Although different types of federally-sponosored open source research communities, one can draw several similar observations regarding the two communities. The slides address fundamental issues for both communities ranging from motivating participation, maintaining infrastructure, and adapting for self-governance.
In an effort to keep improving the web sites functionality and flow we have introduced a new menu to allow you to quickly access the following key areas of the site: forums, wiki, bug tracker and home page. Now moving between these areas of the site can easily be done by clicking one the links in the header of any of the pages. No more having to go back to the main page to select a different part of the site. This new menu also removes the need for a 2nd slider bar on long pages and allows users to bookmark pages directly instead of just the section home page.
We hope you like the new menu and if there is any way we can improve the site more please let us know.
The community now has a Wiki package (DokuWiki) for documentation. Please go to the Wiki menu item on the Home Page to start using it.
Please post questions, comments on ease of use and suggestions for improvements here.
The Federal Highway Administration (USDOT) is conducting a study of the mobility impacts stemming from the street closures around the White House. The White House Area Transportation Study (WHATS) implemented a 24-hour simulation for a large portion of downtown DC for the base scenario, back-cast validation scenario, future base year, and multiple mitigation scenarios.
The forum structure has been modified as part of an ongoing redesign and enhancement effort to make navigating the forums more intuitive. The old posts have been moved to the most appropriate forum.
Please visit the Charm School forum for posting guidelines.
A new How-To that provides specific instructions on the command-line development of TRANSIMS on a Windows platform has been posted in the DOWNLOADS section. This how-to calls for the use of Visual C++ 2005 Express Edition.
Thank you John Leonard and Rob Dell-Ross, for contributing the How-To to the community!

New HowTo's for the Population Synthesizer and using Census 2000 data have been posted. A revised HowTo for the Activity Generator is also now available.
The community web site now implements a member contribution tracking system. The web site has been enhanced to support community management functions and recognize member contributions. In addition, content has been revised or added to make resources more readily accessible. Finally, in an effort to keep up with the rapidly expanding community we have upgraded our server - you should find the site to be faster!
As always, your opinion counts! So, please post your suggestions for improvements here.
How is the community working so far? This status report is the first of an open-ended series of semi-annual assessments of the state of the community. What's your take on how this is working? We're asking all community members to share their opinions in a special forum thread.
Does something seem different? The communitys new look and feel was unveiled as part of an ongoing redesign and enhancement effort that will continue through the fall of 2007. In addition to just looking downright snappy, the new layout was designed to make navigating the site more intuitive and to support a range of new features.
The open source community is our community, so please post here to let us know what you think of the new layout. Both compliments and suggestions for improvement will be accepted!
This document presents the charter comprising the mission statement, the principles of community membership and governance, and the core assets. The document also outlines the by-laws for community organization and governance.
