6.2.6 Highway Safety Software (HSS)

The HSS performs crash prediction evaluations for roadway facilities based on the developed HSM methodologies. Similar to IHSDM, the HSS is another safety software tool developed to implement the HSM predictive method. The HSS software can be used to evaluate the following facility types:
  • Rural Two-Lane Highways and Intersections;
  • Rural Multi-Lane Highways and Intersections;
  • Urban and Suburban Arterials and Intersections;
  • Freeway Ramps and Interchanges; and
  • Roundabouts
The HSS software is distributed as part of McTrans HCS and comes with a comprehensive user’s guide to provide the needed references for the user along with the data requirements.
