Project Meeting 2017.03.16

Multiple Zone Systems Network LOS

• Will review progress from last meeting
• Merged code into master, but not implemented for the example, tests, documentation #159

Data Pipelining

• pipeline branch committed
• Example updated and run on the full example as well (but using all available RAM 160GB)
• todos:
  • write code docs
  • update ActivitySim documentation
  • make the current saving table-states debug statements prettier and put in the log file #160
• It would be good to clean-up the reading and processing of input data (i.e. the default namespace) now that pipelining is implemented. @Everyone - can we do this? This probably means
  • creating new model steps for loading and processing inputs
  • making the default tables just tables with key columns
  • moving all the orca computed columns to a mtctm1 folder/namespace for example
  • (maybe recoding the computed columns as an expressions file instead)
• Running the full example is pretty slow and using 3% of the CPU power. Maybe we should experiment with multi-processing in order to gauge the data pipeline performance? But this is no small task...
• Updated Design page

Random Number Sequences

• Random number sequencing in the pipeline branch as well
• Example updated and run on the full example as well
• todos:
  • write code docs
  • update ActivitySim documentation
  • add random number offset for trips, in addition to households, persons, tours #161
  • add random number to trace results #162
  • add random numbers for each model for each chooser to the relevant tables #163 - households get auto own rnum for example
• Updated Design page

Logsum

• started thinking about how to incorporate logsums - see Adding-Logsums
• see #164 as well
• will prototype revisions and report back to the team

Governance

• @Joe discuss updated Governance plan
• Can we have a draft online by the TRB Planning Applications conference in May?
