BACKGROUND
One of the most common locations for fatal motor vehicle-bicyclist crashes is at intersections, which inherently have a large number of turning conflicts. Reducing these conflicts is a key objective in improving intersection safety across all modes. Of particular concern for bicyclists’ safety at intersections are the conflicts between straight-through bicyclists and motor vehicle right-turns and opposing left-turns. Despite the widespread acknowledgement of this problem, trans...

Portland State University is a subcontractor on NCHRP 17-87 award to Kittelson & Associates, Inc: http://apps.trb.org/cmsfeed/TRBNetProjectDisplay.asp?ProjectID=4373
Challenge
Despite its prevalence as a transportation mode, walking receives less attention than the motor vehicle mode in terms of national guidance and methods to support planning, designing, and operating safe, functional, and comfortable facilities.
Solution
Kittelson partnered with Portland State University and the Hi...
