This data provides observations and measurements used to answer questions of interest regarding how intersection and traffic characteristics impact the frequency and severity of bicycle-vehicle conflicts as part of the study titled “SPR 833 Intersection Treatments and Bicyclist Safety.” Data includes measurements from the field portion of the study used to assess post-encroachment time, hourly road user volumes, and conflict-involved road user speeds that were extracted from field-collected videos in Portland, Oregon. Also included are the measurements from the simulator portion of the study which gathered information relating to average velocity, lateral position, galvanic skin response, eye-tracking fixations, and survey data to describe bicyclist behavior on approach to different intersection geometries and configurations. The study focused on the impact of three intersection treatments which include a bike box, mixing zone, and bicycle signal intended to improve bicyclists safety at signalized intersections.
