Abstract:

This report documents the results of a research project to support CDOT in the area of Safety ; Performance Function (SPF) development. The project involved collecting data and developing SPFs for ; ramp-freeway merge zones categorized as isolated, non-isolated and weave. For each of these three ; categories, data for the period 2007 to 2011 were collected at sites selected to ensure statewide ; geographical representation and coverage of the range of traffic volume and other variables in each ; category. The development of SPFs for the three categories of ramp-freeway merge zones was ; successful. Separate SPFs were developed for Total, fatal+injury (FI) and Property Damage Only (PDO) ; crashes. ; Implementation ; CDOT can use the developed SPFs immediately to apply state-of-the-art methodologies for road safety ; management activities.
