- Technical updates
- There will be another partners-only meeting regarding Phase 9b.
- Agencies should be receiving paperwork for their next fiscal year contracts.
- PSRC validation notebooks with Quarto
- Recently received 2023 survey data and wanted to create summaries for each model component to compare model and survey data, via Jupyter notebooks
- Used Quarto software to create the notebooks – can automatically create reports, books, etc. Similar to rmarkdown, which is more oriented to r. This is more flexible and can be used with python.
- Quarto allowed them to incorporate all the notebooks into one navigateable html
- Formatting can be done through a yaml file
- Option to provide scs files
- You can interact with the graphs (used plotly), so you can click on/off different data sources
- Github repo with PSCR validation code
- SFCTA use of SimWrapper
- SimWrapper was developed in past phases of ActivitySim work.
- Managed through yaml files
- Has ability to do maps of different network-based results
- You only need to configure this once and it can be applied to any model runs
- The tables are all markdown files, and charts are based on a few libraries. The maps support comparisons between model runs.
- Simwrapper accepts geojsons and shapefiles, maybe others, and different projections for mapping.
- Simwrapper for matrices (“skimwrapper”)
- Simwrapper is being used with DaySim for SFCTA, with ActivitySim, and now MatSim in europe
- It now has the ability to load and view/visualization matrices
- Go to Simwrapper.github.io/staging
- Scroll down and click on HDF5 matrix table
- You can drag and drop hdf or omx files and visualize it
- You can use the map or data view
- You can set a file as the base and then add another file and do a comparison
- You need a GeoJSON, but working to add shapefile capabilities
- You can use QGIS to create a GeoJSON and make sure it uses lat/long
- Trip destination alternatives preprocessor is not quite solved, @dhensle and @jpn-- working on a solution
- SANDAG ABM3 runs and gives same (test) results with and without sharrow, no skips, up until trip destination
- Draft PR #870 implements explicit chunking for all interaction models.
- @i-am-sijia confirms skim load time using non-sharrow / legacy SkimDictionary code loads regular ZLIB compressed OMX skims to memory for ABM3 in 20 minutes.
