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:
-
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.
-
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).
- If you want to change the time over which the data is spread, enter a new value (in seconds) in the cell labelled ‘Spread’.
- 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.
