Interactive Highway Safety Design Model (IHSDM): Publications

The IHSDM Library includes all recently published materials on IHSDM in online and/or hard copy format. Past published materials, denoted as archive, are also available; these materials are somewhat dated due to IHSDM's evolving nature, but may still contain information of interest to serious researchers. Some publications are available only for purchase from the National Technical Information Service (NTIS).

Please Note:

Many of the online documents are in Adobe Portable Document (PDF) File format, which requires a free Adobe Acrobat Reader.
