Abstract:

This technology transfer workshop presented transportation planners in the public and private sectors with two successful and closely related studies, conducted respectively by Morgan State University and the University of Virginia. The first module of the workshop is based on the two studies recently completed by a team of researchers at Morgan State University. The Maryland State Highway Administration (SHA) funded the studies. The first study developed local calibration factors for the State of Maryland by adjusting the predicted crash frequencies on state-maintained roadway facilities using the predictive methods of the first edition of the Highway Safety Manual (HSM) (Association of American State Highway Transportation Officials, 2010). While the HSM is the first comprehensive and systematic approach to transportation research, prototype models must be readjusted for each state in order to account for, to name a few, different traffic characteristics, roadway geometrics, socioeconomic characteristics, weather, and geology specific to a study region. The factor for adjusting predicted crash frequencies is called the local calibration factor (LCF). The second study assessed the safety conditions of base and future traffic scenarios for an interchange on I-495. This study used the new chapters of the HSM for Interstate highways. The second module presented the surrogate safety assessment model (SSAM) in assessing safety conducted by researchers at the University of Virginia. The SSAM can be applied to conditions such as when historical crash data are not available or new technology is under consideration.
