This flyer provides information regarding the discontinuation of the Interactive Highway Safety Design Model (IHSDM) software development. However, the Federal Highway Administration (FHWA) will continue to provide free technical support via Geometric Design Laboratory (GDL) staff essentially as long as agencies are still using the IHSDM 2021 (version 17.0.0) software.
