microzones

uses: -activity based model -bike model -remm?

Questions to ask:

• how will this be used for the ABM
• how will this be usded for REMM (ask Andy)
• does the zone make sense for the planning context in which its being used
• how will the socioeconomic data distribute into the zones
  • university employment
• How will the socioeconomic data aggregate into the microzones
• how will traffic within the zone access the road network

Rules of thumb:

• how many microzones per TAZ?
  • usually around 3-10 depending on TAZ side, how developed it is, and the land use mix
• the Outer boundaries of microzones should remain intact; they should not extend pass TAZ boundary where they lie
• keep the microzone shape simple, no donuts, limit extrusions

Environment:

• arcgis pro
• github

What we need:

• taz are too coarse some applications
• create and maintain sub taz level geographic units
• aggregates up and forms taz boundaries
• other sub taz: census blocks, centers, parcels
• places to split
  • current & future land use
  • environmental constraints
  • centers types
  • taz boundaries
  • census blocks?
  • greenfield vs developed

What has been done:

• interactive activity with analytics group
• how they are broken depends on use case
• using all streets network or census block didn't yield useful results land use wise
• zones based off street network, split by taz

Notes:

• there is no right or wrong answer at the moment. That fact that some thought is being put into them is enough for now
