Fast Track: Allowing Bikes To Participate In A Smart-Transportation System

Stephen Fickas Marc Schlossberg
This project focuses on a mode of transportation that is currently left out of V2X (vehicle-to-everything) conversations: bicycling. The project demonstrates how university researchers, city traffic engineers, and signal-controller manufacturers can come together to give bicyclists the same technology appearing on modern vehicles: Green Light Optimized Speed Advisory (GLOSA). GLOSA allows motorists to set their speed along corridors to maximize their chances of catching a “green wave” (i.e.,… Read More

ODOT Understanding Pedestrian Injuries and Social Equity

Nathan McNeil
Portland State University partnered with the project PI Josh Roll of the Oregon Department of Transportation on a two-phase research project examining pedestrian injury and social equity. Past research and planning has highlighted the existence of pedestrian injury disparities throughout the US and some local agencies have performed cursory analysis in Oregon. However, no statewide analysis of pedestrian injuries in Oregon has been completed to see how these injury outcomes differ by race and… Read More
