Developing Safety Performance Functions for Rural Two-Lane Highways that Incorporate Speed Measures

The objective of this research is to develop a predictive methodology for rural two-lane, two-way highways, for consideration by the AASHTO HSM Steering Committee, that incorporates speed measures (or surrogates for speed measures) to estimate crash frequency and severity.
