Creating Arrival Profiles automatically

The quickest and easiest way to create Arrival Profiles is by generating them automatically from an OD matrix: this method will only work if you have correctly defined one on the ‘OD matrix’ worksheet.

To create Arrival Profiles automatically:

  1. Click the button labelled ‘Create Profiles from OD matrix’.

    Arrival Profiles are generated and the relevant data appears in the columns labelled ‘Profile type’, ‘Profile name’, ‘Origin name’, ‘Supply/Entity Type’. A ‘Spread’ value is automatically defined to span the model’s runtime. If an origin appears more than once, the profiles will be numbered ‘<origin>#001’, ‘<origin>#002’, etc.

  2. To add a range of statistical noise to your data, specify minimum and maximum levels in each profile’s ‘Noise’ cell, separating them with a comma.

    For example, if you set minimum and maximum limits of 2 and 5, a cell containing an initial quantity ‘10’ will ultimately be modified to contain between 5 & 8 (if noise is subtracted) and between 12 and 15 (if noise is added).

  3. If you want to change the time over which the data is spread, enter a new value (in seconds) in the cell labelled ‘Spread’.
  4. If your OD matrix was specified in percentages rather than actual number of pedestrians, you will need to enter actual numbers for each time interval of your model runtime.
    Note: If you would like to rename an Arrival Profile after creating it automatically, enter the new name in the relevant ‘Profile name’ cell.
