Missouri Highway Safety Manual Recalibration

The American Association of State Highway and Transportation Officials (AASHTO's) Highway Safety Manual (HSM) was calibrated in 2013 using 2009 to 2011 data to reflect Missouri driver population, conditions, and environment. This project involves the recalibration of the HSM for Missouri. All 25 HSM values (16 facilities) that were previously calibrated will be recalibrated using additional data since 2011. The facilities that previously resulted in calibration values close to or higher that 2.0 will be carefully reviewed. In additional, crash severity distributions in terms of fatal, severe injury, minor injury, and property damage only (PDO) will be produced. Quarterly Progress (Apr-Jun 2016): The verification of previous calibration sites and the identification of substitute sites began this quarter. Substitute sites are needed due to road facility changes or other facility-specific issues. Data collection for traffic and geometric data is continuing. Crash data for the six-year period (2009-2014) was obtained from Missouri Department of Transportation (MoDOT) Traffic Management Systems (TMS) with the assistance from Myrna Tucker and Darrell Knierim.
