Welcome to the Interactive Highway Safety Design Model (IHSDM) software download web site.
An Update to the IHSDM - HSM Predictive Method 2011 Release (version 7.0.1; March 14, 2012) is now available free-of-charge. 2011 AASHTO “Green Book” policies for rural two-lane highways (for both U.S. Customary and Metric units) were added in the IHSDM Administration Tool for use in applicable IHSDM modules (i.e., Policy Review, Crash Prediction, and Intersection Review Modules).
The IHSDM - HSM Predictive Method 2011 Release (initial release on September 29, 2011) includes a Calibration Utility in the IHSDM Administration Tool, to assist agencies in implementing the calibration procedures described in the Appendix to Part C of AASHTO's Highway Safety Manual (HSM), and applied via the IHSDM Crash Prediction Module. In addition, the Intersection Editor was redesigned to help users enter, edit and organize their intersection data.
Through this site you can complete the required registration process and, upon approval, download IHSDM. (Existing registered users, follow the “Download Login” link to access this update. New users, click on the “Download Registration” link.)
The IHSDM - HSM Predictive Method 2011 Release includes six evaluation modules: Crash Prediction, Policy Review, Design Consistency, Traffic Analysis, Driver/Vehicle and Intersection Review. To the extent possible, the Crash Prediction Module (CPM) faithfully implements Part C (Predictive Method) of AASHTO's 1st Edition Highway Safety Manual (June 2010) for evaluating rural 2-lane highways, rural multilane highways and urban/suburban arterials. For more information on IHSDM, visit FHWA's general IHSDM website.
On October 19, 2011 FHWA hosted a web conference on the IHSDM - HSM Predictive Method 2011 Release. To access a recording of the web conference and the PowerPoint slides used during the presentation, click here.
