Why doesn't that traffic signal ever turn green? An evaluation of roadway markings for cyclists



Friday, November 8, 2013 12:00 pm - 1:00 pm
Where: Room 204 of the Distance Learning Center Wing of the Urban Center at PSU
Speaker: Stefan Bussey, PSU CEUG Honors Student
Summary: Signalized intersections often rely on vehicle detection to determine when to give a green light. The 2009 Manual of Uniform Traffic Control Devices (MUTCD) includes an on-pavement marking and curbside sign that public agencies can use to indicate where cyclists should position themselves while waiting at an intersection. This presentation reviews the effectiveness of current markings, signs, and other methods used to help cyclists properly position themselves over detection.

Stefan Bussey is an undergraduate civil engineering student at Portland State University. He is interested in exploring how road users’ interactions with each other and the built environment affect the efficiency and safety of road networks. He currently works as a civil design intern at Harper Houf Peterson Righellis Inc.
