Basic Definitions for Design Modularity of Urban Canyons

Constants

Street Width = 8m (approx. 7.9) (constant) = 8 cells

  • One way roadway = 3m (minimum) = 3 cells (asphalt road[ST])
  • Longitudinal parking = 2.5m (minimum = 2.2) = 3 cells (asphalt road[ST])
  • Sidewalk_1 = 1.2m (minimum = 0.6) = 1 cell (concrete pavement gray[PG])
  • Sidewalk_2 = 1.2m = 1 cell (concrete pavement gray[PG])
  • rest of model (sandy soil[SD])

Building Width = 12m (constant) = 12 cells
