Car-free spaces will be defined by three parameters : size, ownership and time.
Size: a car free space must be at a minimum of one city block (or the equivalent measurement). The measurement may vary according to the geographical location but must be longer than 100 meters (300 ft) or 1000 sq. This excludes pedestrian shopping district and Public parks (Central Park to Yellowstone) but includes Historical areas (old Jerusalem) , car-free villages/towns (Freiburg, Venice), temporary re-purposed public spaces (Paris-Plage) car-free urban districts.
Ownership: a car free space must be publicly owned and access to it must be free of charge.
Time: A car free space does not have to be permanent, but it must be car-free longer than 10 hours to account as a temporary car free space.
A car-free space must be geographically accessible to people and be publicly owned. It aims to be a part of the urban fabric but must be at least 1000 square meters to be considered a car-free space for purposes of this project. . Primary examples are Historical areas (Old Jerusalem), Car-free villages/towns (Freiburg, Venice) and Temporary repurposed public spaces (Paris-Plage). (Other categories of car-free spaces exist such as disaster-impacted areas, privately owned car-free spaces, and areas in which car use is extremely restricted due to extreme weather conditions).A car-free space does not have to be permanent, but it must be “car-free” for a minimum of ten hours to be considered a temporary car-free space
