Parameters
(W) Maximum Walking Distance to Retail Node = 83 m./ 1 minute (at typical 5km/hr)
(A) Detour Angle = 40°
(O) Overlap Percentage = 30%
Method
The D=200 | F=0.9 Simulation output was fed into the network builder function.
The algorithm first detected clusters of dwellings and productive cells.
Continuous Productive plots of larger than 1 ha were identified and wholesale nodes placed.
Retail Nodes were placed throughout the dwelling clusters, based on the (W) Maximum Walking Distance parameter.
From every Wholesale Node towards the closest Retail Nodes a distribution network is built, using several Detour Angles as inputs. 40deg was selected for its balance of low trip time and low overall network cost.
In order to facilitate a continuous social movement individual distribution trees were connected changing the Overlap values. Unlike our sample tissues in the previous experiments, we were unable to generate connectivity and circuitry values to approach the Brooklyn reference tissue. We believe that our test network is too small and this aspect of the network function should be tested again on a larger scale in the future.
The images above show the output from each step of the network algorithm, with evaluations.
