Other IHSDM Software Web Sites

The IHSDM software is currently under development. An access-controlled Developers Web Site is maintained for the IHSDM development team. In addition, several access-controlled download web sites are available to provided access to IHSDM products to those individuals with a requirement for the software. Three categories of special downloads are available:

• the daily build of the Release Candidate Public release distributions,
• the daily build of the Developer release distributions, and
• the current Training release distributions.

In addition to these download sites, there is a Integrators web site for data, documentation and components of interest to software developers that are integrating IHSDM technology into other products. A public web site with documentation (XMLSchema) for the IHSDM-related data is also provided for software developers.

Most of these web sites require a user-id and password for access. For more information, please contact Mike Dimaiuta at FHWA/Geometric Design Laboratory, or 202-493-3332.
