For the 3-30-300 guidelines, the rule indicated by the "300" is residences must be within 300 meters (walking distance) of accessible and usable green at least 1 hectare in size. This can be computed in the Tygron Platform by creating a determination of what green qualifies as accessible and usable green, where at least 1 hectare of such green exists, what green is part of that 1 hectare structure, and what routes towards that structure exists.
How to compute residences within walking distance of significant usable public green:
- Create a Grid Overlay which highlights which locations are to be considered "residences", such that:
Locations which are not residential have a value of 0.
Locations which are a residence have a value of 1. - Create a Grid Overlay which highlights which locations are to be considered "public space", such that:
Locations which are not public have a value of 0.
Locations which are publicly accessible have a value of 1. - Add an Average Overlay, configured so that
Attribute to average is GREEN_M2
Averaging distance is 0. - Add a Combo Overlay, configured so that:
Input A: Public space Overlay.
Input B:GREEN_M2 Overlay.
Formula: AND(GT(A,0),GT(B,0))
- Create a Grid Overlay which highlights which locations are to be considered "residences", such that:
Notes
- If the Travel Distance Overlay does not properly calculate travel routes across certain Functions, such as bicycle paths or pavements, it may be neccessary to change the Function Values of those Functions, specifically the num bicycles and the num pedestrians.
