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...

As part of the City of Portland Enhanced Transit Corridors Plan, the Portland Bureau of Transportation (PBOT) is working with TriMet and Jacobs Engineering to evaluate the impact of red colored transit priority lanes at key locations in and around downtown Portland. Transit priority lanes restrict access to certain lanes, prioritizing transit movement, while sometimes allowing for other users or specific actions - for example shared bus and bike lanes, or shared bus and right-turn lanes.
