Defining precise Arrival Profile data

In many cases, especially in the early stages of a project before more accurate survey data is available, simply spreading the data in the OD matrix between the start and end times of a model will be sufficient.

For more accurate profiles, possibly including peak demand periods or ‘peaks within peaks’, you can define precise time intervals and enter values for each.

Tip: You can define a single row of time intervals for all your Arrival Profiles or create individual rows for particular Entrances.

To define precise Arrival Profile data:

  1. Underneath ‘Time intervals [hh.mm.ss]’ on the right-hand side of the Data Profiles worksheet, add a row of time intervals for the length of your model’s runtime (for example, you might need increments of 15 minutes).
  2. Under each time interval, enter the numbers of pedestrians entering the model.
  3. Ensure you have the correct value in your ‘Spread’ column (see A note on "Spread" values if you require more information).
  4. Repeat steps 1 to 3 for any other rows of time intervals you need to define.
