Drivers’ Attitudes and Behaviors Toward Bicyclists: Intermodal Interactions and Implications for Road Safety
Tara Goddard
Psychology teaches us that implicit biases—attitudes we hold on a level below consciousness, and may not even be aware of—can have a heavy influence on split-second decisions. In a fast-paced activity like driving, with a lot of moving parts in a complex environment, we make those snap decisions all the time. There are obvious safety implications to this, particularly for the most vulnerable road users. That’s why TREC researchers are becoming more and more interested in studying implicit bia...

Evaluation of Different Curb Extension Treatments for Pedestrian Comfort and Safety at Intersections
Nathan McNeil
Sirisha Kothuri
In a project funded by the The District Department of Transportation (DDOT), Portland State University is partnering with the University of North Carolina at Chapel Hill to document and identify factors associated with road user safety and comfort at intersections with permanent versus tactical (both with and without mural art) curb extensions, as well as a set of control locations with no curb extensions. DDOT has over the last few years installed several curb extension treatments on differe...
