Project Meeting 2020.10.29

5b/6a Task 1 Project Management (milestone)

• Working to wrap up 5b
• Budget basically spent but RSG is committed to delivering the scope
• 6a just getting started
• We have an email NTP; I'll check on the status of the contract amendment

5b Task 2 Strategic Planning (milestone)

• Partners discussed and @Joe to propose some revisions
• The document is a living doc so we'll continue to work on it over time

5b Task 10 Support for Three Zone Systems and TVPB (milestone)

• Jeff working on caching strategies
• Jeff checked in latest examples so I'm going to start on QA/QC/verification
• My plan is to:
  • 1. make sure it runs for me and all the settings/inputs make sense
  • 2. do some simple test runs, trace results, visually check results for reasonable transit paths
  • 3. do a full run and check results against Marin TM2
• Can we compare detailed logging between the two setups?
• Results will be a little different, but the general distributions - taps chosen, mode share, district-to-district flows, etc. should be similar
• Let's be clear eyed about adding new dependencies
• Unlike ct-ramp, which does generic calculations and then individual level calculations, we're instead just doing all calculations for a user defined set of market segments for consistency and ease-of-use
• Questions remain about how/when to pre-compute versus on-demand/cache and we're still working toward doing full runs to help us answer these questions
• More task design would have been good
• Let's make sure the documentation includes:
  • highlights all the heuristics, assumptions, etc.
  • Gives good guidance to new users to avoid frustration
  • Assumptions around network coding requirements
• Also include a discussion of the tradeoffs and benefits:
  • more accurate transit walk times
  • station choice / capacity restraint for BART
  • multipath transit routing to better consider tradeoffs of walking time versus ride time
  • basically maz to maz transit assignment
  • greater level of spatial detail / precision for integration with land use modeling
  • slower but worth it in some cases and hopefully will get faster over time through improvements
• Once software in place, we could actually do a comparison of with and without, assuming we build the two data sets required

6a Task 2 Complete Estimation Mode (milestone)

• Newman starting on non-mandatory tour frequency EDB larch reader

6a Task 3 Telecommute Model in Cooperation with SEMCOG (milestone)

• Joel started on the design based on what was done for SANDAG
• Mobility model that predicts days per week typically telecommute
• Based on SEMCOG's 2018 data
• Still need to work on considerations related to telecommuting under COVID
• Plans to talk with Jilan this week and then the ActivitySim team next week
• @Wu/@Joel share SANDAG work ahead of time for background reading

6a Task 8 Maintenance and Support (milestone)

• Helping BYU a little with their implementation
• BYU, Berkeley, and Toledo are getting hands-on experience so let's get some feedback from them
• @Joe to reach out and schedule a discussion at an upcoming Tuesday call
