This is the draft plan for developing a revised version of the current UrbanSim pro forma and developer modules.

Running List of Questions

• How to organize project vis-a-vis full urbansim and urbansim_defaults repositories
• How to release to UDST (how should old models start using the new proforma model?)
• Need to discuss:
  • Releases and versioning scheme
  • Proper setup for an open source python package

Features

Paul's writeup of desired features in the Discourse forum is a good starting place. See the Features page for more discussion.

Key Clients

• We have a consulting contract with MAG (Phoenix) to complete this work. See requirements
• SEMCOG (Detroit) is also interested in improvements to this functionality. See requirements

Team

• Paul S (point person, coding)
• Conor (client support, code review, possible coding)
• Martin (code review, possible coding)

Roadmap

Week 1 (beginning January 30)

Activities

1. Contact interested clients (MAG and SEMCOG) and ask for desired features, implementation, and test data (done)
2. Get or create test data for new features (e.g. a multi-period development) (probably skip this step)
3. Code Review of existing implementations (Tuesday)
4. Review features in detail (Wednesday)
5. Complete high-level project plan (Wednesday)
6. Get signoff from team, Paul (Thursday)
7. Kickoff meeting with team to discuss the plan (Friday)
   • Should come with a detailed, structured plan in response to features
   • Conor and I should have processed and discussed MAG wishlist and data by then (and SEMCOG if possible)
