DATA
20% of accidents
50,000+ crashes
60,000+ injuries and 500+ deaths
14% of all claims of auto damage
occur in parking facilities every year in US.
VOICES
I really wish parking lots were designed with "sidewalks" or "pedestrian paths" down the center of each row (so that you have a parking space, a pedestrian lane, and then another parking space). This would give pedestrians a safe place to walk without having to worry about backing up cars. Other safety features are single direction travel lanes and angled parking spaces. Not sure how feasible all of these are though, as they all require more space.
