Agenda

• Telecommuting update - sensitivity tests
• Admin Discussion

Technical

• Telecommuting update
  • Sensitivity tests
    • Purpose - test whether existing ActivitySim representation of telecommuting is behaviorally unattractive
    • Survey suggests that telecommuters make different number of non-mandatory tours compared to workers not working; confirmed with statistical tests
      • Size of tickers is observations
    • Ran base SANDAG ABM3 run
      • 65% of workers spent 0 days telecommuting; 10% worked exclusively from home; Rest are evenly split between 1-3 days telecommuting
      • Compared to survey, model has much higher number of non-mandatory tours (note, model may not be calibrated to 2022 survey; SANDAG confirmed this was not a focus of calibration to date)
      • Model has about the same level of non-mandatory tours across number of teleworking days per week
        • Existing ABM - can not calibrate it separately
      • Survey suggests telecommutes engage in shorter non-mandatory tours than those not working on the survey day
        • Model average durations do not change
      • Most likely a high telecommuting scenario will not produce different results
      • Survey suggests telecommuters are more likely to engage in non-mandatory tours outside of common work hours than those not working on the survey day
      • Model does not show differences in rate of escorting activities between rate of teleworking, while survey does show a difference
    • Not clear at this point what exactly needs to change to best enhance the model; Would be ideal to figure out what the simplest or most optimal fix is;
