All HSS subscriptions include technical support (automatic updates, downloadable updates, toll-free telephone assistance, data file review, etc.) for the first year. Thereafter, an annual support subscription must be maintained to continue these services, but no more upgrade fees are required.

HSS has expanded its capabilities and is now offered as a stand-alone product. For those interested in both HSS and the Highway Capacity Software (HCS), McTrans offers bundled discounts of up to 40%.

HSS is a typical Windows installation and the system should meet the following minimum requirements including Windows XP/Vista/7 or newer, 512MB RAM, VGA+ Monitor and 750 MB hard drive space available. This will be a completely new installation, separate from any existing version. The installation program will present a license agreement, which must be agreed to for the installation to proceed.

No issues have been discovered in testing or reported by users.

The Highway Safety Software (HSS) implements Crash Prediction Models from Highway Safety Manual (HSM) 1st edition and the HSM Supplement, which means the following chapters are included:
  • Chapter 10 – Rural Two-Lane, Two-Way Roads
  • Chapter 11 – Rural Multilane Highways
  • Chapter 12 – Urban and Suburban Arterials
  • Chapter 18 – Freeways
  • Chapter 19 – Ramps

HSS is designed to determine the predicted and expected number of crashes for segments and intersections following the Predictive Method, which is explained in the aforementioned HSM chapters. The basis of the Predictive Method is calculating a Safety Performance Function (SPF) and applying Crash Modification Factors (CMFs) based on certain geometric and safety feature data in the intersection/segment. Whenever Historical Crash data is available, HSS allows Empirical Bayes method implementation.

The Highway Safety Software also includes new methods developed as a product of research projects. These methods were implemented as published in the reports listed below, and may be adjusted when formally incorporated in a future release of the Highway Safety Manual:

  • NCHRP Project 17-70 – Roundabouts
  • NCHRP Project 17-68 (Chapter 3) – Intersections with All-Way Stop-Control
  • NCHRP Project 17-68 (Chapter 4) – Three-Leg Intersections with Signal Control on Rural Highways
  • NCHRP Project 17-58 (Chapter 5) – Urban and Suburban Segments with Six or More Lanes
  • NCHRP Project 17-58 (Chapter 6) – Intersections of Urban and Suburban Arterials with Six or More Lanes
  • NCHRP Project 17-58 (Chapter 7) – Urban and Suburban One-Way Arterial Roadway Segments
  • NCHRP Project 17-58 (Chapter 8) – Intersections of Urban and Suburban One-Way Arterials
  • NCHRP Project 17-68 (Chapter 5) – Intersections on High-Speed Urban and Suburban Arterials
  • NCHRP Project 17-68 (Chapter 8) – Crossroad Ramp Terminals at Single-Point Diamond Interchanges
  • NCHRP Project 17-68 (Chapter 9) – Crossroad Ramp Terminals at Tight Diamond Interchanges
  • NCHRP Project 17-84 (Chapter 4) – Pedestrian and Bicycle Safety Performance Functions
