TRB conducted a webinar on Thursday, August 11, 2016 from 2:00PM to 3:30PM ET on crash modification factors (CMFs). A CMF is a number used to quantify how effective a safety measure is expected to be when implemented. This webinar discussed the basic study types used to develop CMFs, what data are needed, and how to avoid potential biases.
This webinar was requested by the TRB Standing Committee on Highway Safety Performance. A certificate for 1.5 Professional Development Hours (PDHs) was provided to attendees who registered and attended the webinar as an individual. Contact Reggie Gillum at
RGillum@nas.edu for instructions on receiving a copy of the recorded webinar.
Here are the slides.
