Highway Safety Manual in States II -- Freeway/Software

The American Association of State Highway and Transportation Officials (AASHTO) is preparing to release a revision to the Highway Safety Manual (HSM) that includes models for freeway segments, speed-change lanes and interchanges. Select models that are relevant to Mid-America Transportation Center (MATC) states will be calibrated using local sites and local crash data. The calibration of such models will ensure that they reflect local driver population, conditions and environment. The HSM has a related software package, the Safety Analyst (SA). This software will be investigated for the generation of the annual needs list (high-severity facilities). There have been some facilities that are unique to the MATC states that do not have HSM models. Two examples are the diverging diamond (or double-crossover) and the J-turn. This project will also develop Safety Performance Functions for these innovative geometric designs that are designed to reduce severe crashes.
