INTERACTIVE HIGHWAY SAFETY DESIGN MODEL (IHSDM) SOFTWARE VERSION 17

The IHSDM Version 17 software download is composed of a suite of software
analysis tools used to evaluate the safety and operational effects of geometric
design decisions on highways.

IHSDM is a decision-support tool that provides estimates of a highway design's
expected safety and operational performance. Results of the IHSDM support
decisionmaking in the highway design process. Intended users include highway
project managers, designers, and traffic and safety reviewers in State and local
highway agencies and in engineering consulting firms.

The Federal Highway Administration (FHWA) recently acquired the .gov domain for
the Interactive Highway Safety Design Model (IHSDM) program. Although FHWA used
to be associated with the www.ihsdm.org domain name, it was recently purchased
by another entity unrelated to FHWA. As such, FHWA is no longer affiliated with
the .org site and thus not associated with any content that appears on the .org
domain name.
