From bike lanes to pedestrian plazas, the urban transportation systems of American cities – and Philadelphia specifically – are becoming more multimodal. Yet the increasing number of cyclists and pedestrians has led to a rise in conflicts and crashes. This is a public health epidemic requiring transportation planning science: Pedestrians are sustaining fatal and serious injuries because of crashes at dangerous intersections in Philadelphia’s University City.
Safe Urban Mobility: A User-Based Safety Analysis of the Chestnut Street Bike Lane
Chestnut Street in University City, Philadelphia
This transportation planning research project collects the missing user-based information on vulnerable road users (pedestrians and cyclists) using Eye Tracking Glasses, thereby 1.) enabling the study of the new protected bike lane on Chestnut Street in West Philadelphia/University City and 2.) assisting the city of Philadelphia in deploying safe urban infrastructure.
The initial results indicate the most “high-stress” portions of the bike lane; develop metrics to compare stress and safety between protected and unprotected bike lanes; and how signage can be improved to maximize safety information to cyclists.
