Project Meeting 2018.06.21

Stop models

Trip mode choice implemented in branch trip-mode
Updated trip destination choice to use trip mode choice logsums now as well
Needed to revise and clean-up mode choice utility specifications to be easier to use / finalize
@Jeff working on the full scale example run now
- A few trips failing with all zero_probs, and still investigating
- Issue in tour_mode_choice caused by the fact that some WALKDIST and BIKEDIST skims are asymmetrical (O->D vs. D->O) so tour_mode_choice would allow outbound walk (<3mi) but the return was >3mi, so they couldn’t get back
- Remember transit subzones were not implemented in this version
Once complete, we'll do a pull request and then update documentation and re-release

Example model design and sub-model designs updated
Sub-models hyperlinked flow chart integrated
Updated listing of all sub-model input files
Updated data schema and built auto-documentation tool based on our data pipelining technology
Updated getting started steps
Lots of little clean-up in the docstrings and existing documentation
Released Friday June 8th
@Ben will update and re-release for trip mode choice updates

Updated Progress Report through trip mode choice
Current scope will be completed in a few days and all funds will be expended by then
Updated Phase 4 Scope of Work posted for comment
- Moved multiprocessing to the top since it is the next important step
- Updated shadow pricing design to be flexible for use in all regions - allow for specifying classifiers for types of persons, land use, and geographies in the form of expression files for example
- Moved continued verification and clean-up to the end since it's an ongoing part of the overall effort
- Moved multiple zone systems to the end and suggested we test with either MTC TM2 or SANDAG instead of TM1 + fake data
Lots of discussion about how best to implement support for multiple zones systems
- No one wants to create fake data for the TM1 example
- @Lisa and @Wu to think about setting up MTC and SANDAG
- @Ben to break out task into sub-tasks
  - Setup example to implement new features for
  - Add support for multiple zone systems
  - Implement transit virtual path building
- See table below for multiple zone systems in use by region
See you Monday night in Atlanta

Region	TAZs	TAZs + MAZs/parcels	TAZs + MAZs/parcels + transit stops	Notes
PSRC		X		gets transit access/egress times from nearest stop in the buffered MAZ/parcel file
SFCTA		X		gets transit access/egress times from nearest stop in the buffered MAZ/parcel file
MTC TM1	X
MTC TM2			X	does transit virtual path building
SANDAG			X	does transit virtual path building
SEMCOG	X			current trip-based model
