Enclosure: Jaskiewicz described this as the edges of a site, and the degree to which the edge is complete. I will be considering enclosure as scale. A wide open site with a large width will be one extreme, while a tight and claustrophobic site would be the other. (Site 1: Gran Via de les Cortes Catalanes, and site 5: Rambla del Raval, are the most open sites, while site 3.2: Carrer de la Cera is the tightest)
Physical Conditions: Jaskiewicz broadly explains this as, "anything else that plays a role in pedestrian experience." For my study, physical condition will focus on the materials used, and their condition. A site that lacks a variety of materials and/ or shows wear and tear, would receive a grade of 1, while a site that uses a wide range of materials and/ or is in immaculate condition would receive of 5.
Organization: The degree to which traffic lanes for pedestrians, bicycles, and vehicles are provided. A site that has very distinct moving lanes for all three would receive a grade of 5, while a site that has no lanes would receive a grade of 1. (Sites 1 and 3.2 are the upper and lower extremes once again.)
