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...
