Bike lanes experiment measures cyclist response to infrastructure design

According to the Pennsylvania Department of Transportation (PennDOT), Philadelphians were involved in 740 crashes between 2011-16—killing 20 cyclists and causing a major injury to 80 more.

For pedestrians, those numbers are measured in the hundreds. Thus, making cycling safety not just a problem but, increasingly, a priority.

Enter, Megan Ryerson, an assistant professor of city and regional planning at PennDesign, research director of the $14 million PennDOT-funded Mobility 21 transportation research center, and, uniquely, director of a brand-new project that attempts to document not just these crashes, but the many more near-crashes that happen every day.
