Cyclists and Intersections: A Seminar Double Header

For the next two weeks, the PSU Transportation Seminar will focus on what happens with folks riding bikes at intersections:

 

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

Speaker: Stefan Busse, PSU CEUG Honors Student

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

When: Friday, November 8, 2013, 12-1 p.m.

Where: PSU Urban Center Building, SW 6th and Mill, Room 204

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.

Cyclist Compliance at Signalized Intersections

Speaker: Sam Thompson, PSU Graduate Student

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

When: Friday, November 15, 2013, 12-1 p.m.

Where: PSU Urban Center Building, SW 6th and Mill, Room 204

Summary: Although the running of red lights is perceived by motorists as a commonplace behavior for cyclists, little research has been done on the actual rates of cyclist compliance at signalized intersections. Furthermore, little is known about the factors that influence cyclist non-compliance. This research seeks to illuminate the rates of and reasons for infringement against red lights using video footage and survey data from cyclists in Oregon.
