We are committed to making decisions that promote the success and well-being of our campus community. Until further notice, all live events hosted by TREC will be online only.
Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online at 11:30 AM.
This seminar discusses how pedestrian race and gender can influence drivers’ behavior in interactions with pedestrians at crosswalks. Three speakers will present different lenses to look at this topic.
Kimberly Barsamian Kahn, a researcher at Portland State University, will discuss research exploring how pedestrian race and gender influence drivers’ behavior in interactions with pedestrians at crosswalks. One dangerous potential point of conflict for pedestrians within the transportation system is interactions with drivers at crosswalks, and racial minorities are disproportionately represented in pedestrian fatalities. Research tested the hypothesis that drivers’ would demonstrate unequitable yielding based on pedestrians’ race and gender in three controlled field experiments at an unsignalized crosswalk. Trained and matched confederate pedestrians simulated an individual pedestrian crossing, while observers recorded drivers’ stopping behavior, number of cars passed, and time until a driver yielded. Study 1 included Black and White male pedestrians, while Studies 2 and 3 crossed pedestrian race (Black/White) and gender (male/female).
Results indicated that Black pedestrians were less likely to have a car stop, were passed by more cars, experienced longer wait times, and had cars stop closer. Results suggest implicit bias may impact drivers’ stopping decisions, indicating a subtle way in which discrimination perpetuates. Less safe crossing experiences may dissuade minorities from adopting healthy transportation modes and contribute to disproportionate safety outcomes based on race and gender.
George Stern, Vice President of Deafblind Citizens in Action, will speak on his lived experience as a deafblind, visibly Black male pursuing freedom of movement across diverse landscapes, including four urbanscapes. The narrative will touch on themes of gentrification, transportation culture, and the utility-dependence perception gap.
Peter Koonce of the Portland Bureau of Transportation will offer a traffic engineer's perspective on this topic and address real-world applications.
KEY LEARNING OUTCOMES
- Mobility of all inhabitants is a crucial consideration in designing physical social spaces.
- Drivers’ yielding behavior at crosswalks is influenced by pedestrians’ race and gender.
- At unmarked crosswalks, stopping rates were very low and few differences emerged based on pedestrian race and gender.
- At marked crosswalks, drivers were less likely to stop for Black and male pedestrians, and when they did stop, they were more likely to stop closer to Black male and Black female pedestrians at a marked crosswalk.
- African American and Black pedestrians discussed how these are stressful interactions that harm their walking trips.
