Research Highlights
Shared Space and Bicyclists
Allison Duncan
Shared space is a traffic calming technique and design concept. The technique is relatively new, and the majority of existing research concerns pedestrians only. This mixed methods study will be international in scope focusing on intersections in England. The goal of this dissertation is to understand how cyclists perceive and travel through shared space intersections by observing cyclists as they traverse selected sites and control sites as well as intercepting and surveying those cyclist...

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...
