Execution procedure

Short-term Calibration Running Instructions

• Inputs

  • ~/SimMobST_Calibration/data/SensorMapping, ~/SimMobST_Calibration/data/TravelTimeData contain the reference (external) data for the calibration in the .RData file format. These files typically do not change.
  • To update the .RData
  • The configure_Whole_set.m file contained in ~/SimMobST_Calibration/ the initial values of the parameters for the simulation, along with their upper and lower bound values.

• Execution of the Calibration loop

  • When new Trip chains are provided by MT
    • Output the Trip chains from the database into TripChain.csv and place it in the folder ~/SimMobST_Calibration/data/TripChain
    • Run Ffunction.R: Open the Ffunction.R file and dnsure start and end time is set in the code
      • Using RStudio: Open file ~/SimMobST_Calibration/data/TripChain/Ffunction.R, then select all the contents of the file and press Ctrl+Enter
      • Using Terminal: Navigate to the folder Open file ~/SimMobST_Calibration/data/TripChain/ and type Ffunction.R to execute.
    • Run the Calibration
      1. Clear the RESULT folder
      2. Run the queries in ‘reset_db.sql’
      3. Open Matlab (type matlab in the Terminal from any location) and ensure working directory is ~/SimMobST_Calibration.
      4. Open file wspsaNTE_enhanced.m and click the ‘run’ button
  • When existing Trip chains are to be used
    • Run the Calibration
      1. Clear the RESULT folder
      2. Run the queries in ‘reset_db.sql’
      3. Open Matlab (type matlab in the Terminal from any location) and ensure working directory is ~/SimMobST_Calibration.
      4. Open file wspsaNTE_enhanced.m and click the ‘run’ button

• Outputs

  • Output files will be located at ~/SimMobST_Calibration/RESULT
  • To analyze calibration result, we run the CalResultAnal.R
