Project Meeting 2021.02.25

Task 1 Project Management (milestone)

• Should we establish AMPO resources for this project:
  • Paid GitHub organization account, see https://github.com/organizations/ActivitySim/settings/billing. This is needed for storing the large files at https://github.com/rsginc/activitysim_resources. This account is currently $5/month and paid by RSG.
  • Paid TravisCI test system account, see https://travis-ci.com/organizations/ActivitySim/plan. This is needed for the test system and is currently $69/month and paid by RSG.
  • The website, see http://www.activitysim.org/. The domain name is now owned by AMPO and there is a cost to maintain the name and the site.
  • A large Windows server with ~48 cores and ~512GB RAM to run full scale model runs for testing. This is currently done using RSG servers. This could be an AMPO owned computer or Amazon AWS cloud service / Microsoft Azure cloud service resource. The costs depend on usage, but the cost is substantial.
  • AMPO recently purchased the trademark for ActivitySim as well
  • Joe/Caitlin to discuss
• Contracting / bench update
  • Partners meet to discuss bench setup and future work orders
  • Plan to get Informal RFPs (IRFPs), which are like task orders on an on-call
  • Planning to get going in a few weeks
  • Partners follow-up with Joe if you missed the call
  • IRFPs will require a 3-5 page response
• Agenda next week
  • Clint and Joel share recent work for ARC and SEMCOG

Task 2 Complete Estimation Mode (milestone)

• Newman working through submodel examples and coordinated with Doyle on improvements as needed
• We plan to circle back and discuss potential additional improvements once through all the submodels

Task 3 Telecommute Model in Cooperation with SEMCOG (milestone)

• Joel/Albab working on person occupation/industry approach based on available data
• I'll add more depth to the design page

Task 4 Transit Pass Ownership Model in Cooperation with SEMCOG (milestone)

• No updates
• I'll add more depth to the design page

Task 5 Performance Enhancements (milestone)

• Presampling pushed to develop2 for PSRC testing
• Stefan to do some testing, including shadow pricing convergence
• Jeff finishing up tracing and then I'll review again for the merge to develop

Task 6 Prototype multiple models test system (milestone)

• Jeff and I further discussed and I need to update the draft plan
• Jeff continuing to get agency examples in order for the test system improvements
• We need to continue to better define/differentiate test vs agency example...how do they blur? how are they different?
• Let's inventory a list of issues/ideas
• Every code change needs test backing
• Regarding the frequency of updating agency registered models, how close do we want to tie the PSRC owned to day-to-day ActivitySim development?
• Small/cropped examples tested by Travis - yes, Full scale examples - no, but what's in the middle? And its important we don't miss key aspects of the system such as scaling/performance by not adequately testing "complete" examples
• I'll review ODOT's input checker stuff from a few months ago since its relevant (including the list of checks here)

Task 7 Input checking and error handling and pipeline improvements (milestone)

• No updates

Task 8 Maintenance and Support (milestone)

• Accessibility chunking pushed to develop2 for SANDAG testing
• SANDAG has successfully ran 100k HHs all the way through using SANDAG three zone system, skims, and land use!
• Took 560 minutes single processed
• Plan to look at high level results and test multiprocessing
• Representative logsums will help significantly with runtimes
