TREC Final Reports

The 2010 Highway Safety Manual (HSM) provides methods for predicting the number of motor vehicle crashes on various roadway facilities. However, it includes only a rudimentary method for predicting the number of bicycle-related crashes. Despite research demonstrating that bicycle volume is an important factor in estimating number of bicycle crashes, the method does not include the volume of bicyclists using the roadway. To remedy this, this project will investigate the potential of various simplified methods to include bicycle volumes in future versions of the HSM. By studying locations where bicycle traffic volumes, motor vehicle traffic volumes, bicycle collisions, and roadway …


Walking While Black: Racial Bias At The Crosswalk, Kimberly Barsamian Kahn Oct 2017

Walking While Black: Racial Bias At The Crosswalk, Kimberly Barsamian Kahn

TREC Project Briefs

This project, led by Kimberly Kahn of Portland State University, explores social identity factors (race and gender) that 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. In 2010, there was one crash-related pedestrian death every two hours and an injury every eight minutes, and racial minorities are disproportionately represented in these pedestrian fatalities. In light of this disparity, this project examines whether racial discrimination occurs at crosswalks, which may lead to disparate crossing experiences and disproportionate safety outcomes.

TREC Final Reports

This project explores social identity factors (race and gender) that 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 (NHTSA, 2009). In 2010, there was one crash-related pedestrian death every two hours and an injury every eight minutes, and racial minorities are disproportionately represented in these pedestrian fatalities (CDC, 2013). In light of this disparity, this project examines whether racial discrimination occurs at crosswalks, which may lead to disparate crossing experiences and disproportionate safety outcomes. Racial minorities experience racial discrimination across various …
