WELCOME TO THE NGSIM COMMUNITY WEBSITE

You are encouraged to register as a member on this site.  Once registered, you will be given the opportunity to become a "Friend" of one or more active work groups in the community, including:

  • Algorithms -- Exploring research regarding the improvement of simulation algorithms
  • Research Needs -- Investigating the direction and needs of simulation research
  • Data Sets -- Researching the provision of data to support simulation needs.

 Registering on the web site will provide you with basic access to documents, data and research created by the NGSIM Program and Community.  Becoming a "Friend" of one or more of the work groups will provide you with the ability to participate in work group discussion forums, and be recognized by the Community as a contributor to the work groups.  Recognition as a contributor to the NGSIM community allows an individual further participation access to on-going research efforts as well as the possibility to directly participate in the government of the community.

The Next Generation Simulation (NGSIM) program was initiated by the United States Department of Transportation (US DOT) Federal Highway Administration (FHWA) in the early 2000's.  The program developed a core of open behavioral algorithms in support of traffic simulation with a primary focus on microscopic modeling, and collected high-quality primary traffic and trajectory data intended to support the research and testing of the new algorithms. The NGSIM program has actively engaged traffic simulation vendors to accelerate the inclusion of advanced or improved algorithms in the commercial models used across the world. 

The NGSIM program has resulted in unprecedented collaboration between software developers, researchers, and software tool end-users.  The end result is that there is now a critical mass of individuals composing an NGSIM community,  a diverse and collaborative collection of academics, public sector staff, vendors, consultants and other analysts seeking to improve the underlying fidelity and accuracy of traffic simulation analysis. There remains strong interest among the NGSIM community members to continue the research momentum, and maintain and expand the products developed as part of the NGSIM program. The NGSIM community is an Open Source community, managed and governed directly by its members and contributors.

To support this new Open Source NGSIM community, this web site provides capabilities for members to communicate and share information directly with each other, and to govern the community.  This website also provides continuing access to the data and documentation developed as part of the NGSIM program.
