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...

Human Wayfinding
Amy Parker
The Tri-County Metropolitan Transportation District Of Oregon (TriMet) is in need of specialized support to improve and promote effective resources in human wayfinding and navigation at its transit centers. Areas of need include, but are not limited to:
1. Tactile Maps: Providing tactile spatial information accessible to people who are blind or low vision.
2. Written descriptions of stations and routes: information needed by people who are blind or low vision, to allow independent mobil...
