There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number of bicyclists is increasing, safety remains a top concern. In urban areas, a common crash type involving bicycles at intersections is the “right hook” where a right-turning vehicle collides with a through bicyclist. While geometric treatments and...

The latest report from the National Cooperative Highway Research Program (NCHRP), “Road User Understanding of Bicycle Signal Faces on Traffic Signals” (20-07/Task 420), zeroes in on some key gaps in research and practice around road users' comprehension of bicycle-specific traffic signal faces.
Led by Chris Monsere and Sirisha Kothuri of Portland State University, the research team included members from Oregon State University and Toole Design Group. The research team reviewed the current ...
