Shared space streets: design, user perception and performance

Shared space is becoming an increasingly well-accepted approach to street design, pursuing improvement of street uses on foot without restricting other modes of movement. This approach introduces a degree of uncertainty regarding application of traffic rules by minimising traffic signs and conventional physical demarcations to enable different users to share the road space and negotiate their movement through and across it. Despite existing evidence for reduced traffic accidents and casualties, this type of street design remains an unorthodox approach. This article addresses the key issues of road safety, user comfort and revitalization aspects of the shared space, raised in the last decade with a focus on pedestrian users. Based on analysis of the layout, performance and user perception of six study areas, evidence reveals how these schemes affect safety, comfort, the conventional spatial distribution or hierarchy of users, and public life
