• Abstract:
  AASHTO’s Highway Safety Manual (HSM) facilitates the quantitative safety analysis of highway facilities. In a 2014 ; supplement, freeway facilities were added to the original HSM manual which allows the modeling of highway ; interchanges. This report documents the calibration of the most vital freeway interchange facility types in Missouri. These ; facility types include nine freeway interchange terminals, including diamond, partial cloverleaf, and full cloverleaf ; interchanges. The non-terminal facilities included entrance and exit speed-change lanes, and entrance and exit ramps. The ; calibrated facilities applied to both rural and urban locations. For each facility type, sample sites were randomly selected ; from an exhaustive master list. Four types of data were collected for each site: geometric, AADT, traffic control, and crash. ; Crash data was especially noteworthy because of the crash landing problem, i.e. crashes were not located on the proper ; interchange facility. A significant companion crash correction project was undertaken involving the review of 12,409 crash ; reports, and the detailed review of 9,169 crash reports. Using the corrected data, 44 calibration values were derived for ; freeway terminal and non-terminal facilities. These values are the first reported freeway interchange calibration values ; since the release of the 2014 HSM supplement.
