Project Meeting 2016.08.25 - bellevuewa/BKRCast GitHub Wiki

Employment data

State attorney general interpretation that only employment department consultants can access ES202/QCEW data
Project team will continue to work on changing this
RSG to share other state employment data confidentiality / NDA forms
PSRC to compare LEHD employment data model runs to current model runs
Maybe mashup LEHD, QCEW, InfoUSA instead so source of data unknown?
Project will need best employment data at the parcel level by Nov/Dec

RSG started working on getting the quick-and-dirty BKRCast model setup
Using new zone system and network
PSRC shared latest model setup and inputs (except for parcel employment) with RSG
BKR still refining network so will need to batch in again at a later point
Will share with BKR once working

Mark discussed draft plan for evaluating sampling, randomness variation
Three stages – spatial sampling, destination choice sampling, overall model feedback sampling
Spatial sampling
- 5 spatial sampling options and 10 random seeds
- Therefore 50 1 iteration Daysim runs; no EMME stuff at this point
- Review standard deviation of outputs for common metrics
- Summarize at the region, BKR, district, and TAZ level
Select 2 most promising spatial sampling plans and do different destination choice sampling options
- 2 by 10 seeds by 3 dest choice samples = 60 model runs
Select 2 most promising dest choice sampling plans and do different overall model feedback sampling options
- 2 by 10 seeds by 3 samples = 60 model runs
- Will run EMME and include assignment metrics as well
Hu to draft new district scheme based on BKR neighborhoods
RSG started implementing spatial sampling plan in Python
- Reads hdf5 full population file, TAZ sample rate file and other settings, and writes new sampled hdf5
