Documentation

  • Shuming prepared a list of questions related to inputs/settings
  • @RSG to update User's Guide in response to questions

Calibration Update

  • Hu sensitivity tested terminal times and the current settings appear to be reasonable
  • COB sent highway and transit counts to RSG
  • Nagendra compared the highway and transit counts to the latest model runs and there appears to be a bug/issue
  • All the highway screenline volumes are too high - 200-300% percent too high
  • Otherwise results generally look ok except for a few noted issues:
    • Trip lengths are generally a bit too long
    • There are not enough trips to Bellevue downtown from places other than Bellevue and Kirkland
  • Results outside BKR reflect the larger zone sizes
    • For example, trip lengths are even longer and transit boardings are low
  • @RSG to investigate highway volumes issue. It seems likely due to an issue with building demand matrices by time-of-day or EMME network settings. Will share calibration/validation summaries once resolved.
