              Abstract:This provides information regarding technical support for Interactive Highway Safety Design Model (IHSDM). The Federal Highway Administration (FHWA) has discontinued IHSDM software development. However, FHWA will continue to provide free technical support via Geometric Design Laboratory (GDL) staff through at least September 2024, but essentially as long as agencies are still using the IHSDM 2021 (version 17.0.0) software.
