Fragment of Generative Code for Neighborhoods


Spatial distribution of cars within the neighborhood

Originally written for Strood Riverside, September 2005 Each neighborhood is, to a greater or lesser extent, pedestrian at its core. This pedestrian core is essential to the life of the neighborhood.

In order to bring cars into the neighborhood, for parking, convenience, movement, emergency and so on, the cars must be placed in such a way that they do not impinge unduly on the pedestrian center and central zone.

It is a good idea to create a gradient, in the neighborhood, which assigns a probability of cars being present in each ring, this probability being very close to 0% in the central core area, and perhaps close to 100% at the perimter of the neighborhood, with concentric rings of decreasing probability as one passes from outside to inside.


  • Draw a series of concentric rings, from neighborhood perimeter to core.
  • The number in each ring, defines the % of area that may be devoted to cars in that ring.
  • In this calculation space which allows passage of emergency vehicles can be counted at half its actual area.
  • The total area of space in the neighborhood, for cars, driveways, and emergency access, summed over all the rings, may not exceed 18%.

    Later plans showing the actual parking positions and roads positions will have to conform to this arithmetic.
