Project Meeting 2017.04.28

Separating core from model (mtctm1)

• We forked the repo and significantly cleaned up the package organization
• Draft pull request to discuss - https://github.com/activitysim/activitysim/pull/180
• We now have:
  • activitysim.core - logit, pipeline, expressions, tracing, etc
  • activitysim.mtctm1 - example sub-models
  • activitysim.cdap
• On the call we decided to revise this to be:
  • activitysim.core
  • activitysim.abm
    • models - example sub-models
      • including cdap
• ActivitySim's organization is looking similar to that of AstroPy and Matsim
• We're still figuring out how different agency models such as MTC and SANDAG will cooperate within the repo; of course we want as little code duplication as possible
• When we do pull requests, we need to merge into a new branch, not the master
• @Jeff - revise the package setup and @Ben - update the documentation (for the pipelining and random number sequences as well)
• We will create a new pull request once it is ready-to-go

Governance

• @Joe is working on finalizing the administrative section
• @Clint is working on finalizing the technical section
• @Joe will address Clint's concern about a potential conflict w.r.t. the AMPO contract
• We'll post our plan ahead of the TRB PA meeting in just over two weeks
• Our ActivitySim presentation is Wednesday

Project progress

• Tasks 2 and 3 basically done, and cost was on budget
• Have spent some budget from task 6 for repo clean-up
• Will soon start on task 4, logsums

SANDAG multiple zone systems

• We have NTP on the extension to integrate and speed-up the prototype #167
• Will add networkLOS engine to core and update abm.models to use it as well
• The example models will still use TAZ to TAZ network LOS since they are TAZ-level models
