TRB conducted a webinar on Tuesday, October 20, 2015 from 2:00 PM to 3:30 PM ET that examined retroreflectivity in sign and pavement marking from the perspective of a state Department of Transportation (DOT). This webinar discussed the basic measurement of sign and pavement marking retroreflectivity using equipment available to state DOT employees. This webinar presented a summary of sign retroreflectivity assessment methods used to meet the new Manual on Uniform Traffic Control Devices (MUTCD) requirements. This webinar also presented advancements in Road Markings to Support Autonomous Vehicle Technologies.
This webinar was organized by the TRB Standing Committee on Sign and Pavement Markings.
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 from the presentations.
