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...

Understanding Factors Affecting Arterial Reliability Performance Metrics
Avinash Unnikrishnan
Sirisha Kothuri , Jason Anderson
Researchers from Portland State University (PSU) partnered with Washington County, Oregon to offer data-driven strategies in prioritizing funding for travel time reliability improvements on their urban arterials. The vast majority of existing research on travel time reliability has focused exclusively on freeways. Funded by the National Institute for Transportation and Communities, PSU researchers Avinash Unnikrishnan, Sirisha Kothuri and Jason C. Anderson leveraged Bluetooth sensors provided...
