The Public Release (Version 2) of Surrogate Safety Assessment Model (SSAM)
The Public Release (Version 2) of Surrogate Safety Assessment Model (SSAM) is now available for free downloading at http://www.itssiemens.com/research/ssam . The SSAM is a software application designed to conduct conflict analysis and to perform statistical analysis of vehicle trajectory data output from microscopic traffic simulation models including VISSIM, AIMSUN, Paramics, and TEXAS. The software computes a number of surrogate measures of safety for each conflict that is identified in the trajectory data and then computes summaries (mean, max, etc.) of each surrogate measure. This approach circumvents the need to wait for "abnormally high" crashes to actually occur, allows assessments of hypothetical designs and control alternatives, and is applicable to facilities where traditional, volume-base crash-prediction model have not been established.
