14% of all claims of auto damage 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. Posted by: UMDTerpsGirl | November 2, 2009 12:10 PM Data source: national safety council injury facts 2015

Modeling

Pedestrian flow(orange) Entrance Exit Obstacle Passway Vehicle flow(red) Parking spots Layout of a parking lot

Walking to destination and back to the parking spot Parking into the spot Entering the garage Leaving the garage Leaving the parking spot Yielding to other drivers or pedestrians Cruising: looking for a parking spot A typical drivers‘ behaviors

Traffic Rules Vehicles in passway yield to pedestrians. Vehicles wait for vehicles in maneuvers. Vehicles in subroutine yield to main routine. At intersection: first come, first go.
