Applying Pulse

The Pulse function enables you to quickly define a Standard Pulse (single fixed value over a given time interval) or a Pulse Train (repeated standard pulse over a specified period of time).

The following procedures assume that you have already selected a suitable Data Profile. Availability profiles work slightly differently from the other data profiles, so their procedures are described in Applying Pulse to Availability Profiles .

To apply Pulse:

  1. Right-click in the graph and select Apply > Pulse.

    The ‘Pulse/Pulse Train’ dialog box is displayed.

  2. Enter the Start time for the Pulse in seconds.
  3. Enter the Duration of the Pulse in seconds.
  4. Enter the number of People (Entities) to apply to each second of the Pulse.

    To apply a Pulse Train at this point, see the next procedure below.

  5. If you don’t want the pulse to overwrite the existing data and prefer the pulse to be added to the existing data, untick the Overwrite box under ‘Pulse Application’.
  6. Click the OK button to apply the Pulse to the Data Profile.

To apply Pulse Train:

  1. Enter the Pulse settings as described in the procedure above.
  2. Tick the Pulse Train box.
  3. In the On Duration box, specify the number of seconds that the pulse will apply the ‘People’ value in a single cycle of the pulse.
  4. In the Off Duration box, specify the number of seconds that the pulse will not apply the pedestrians value (that is, no demand will be applied) in a single cycle of the pulse.
  5. If you don’t want the Pulse to overwrite the existing data and prefer the pulse to be added to the existing data, untick the Overwrite box.
  6. Click the OK button to apply the Pulse Train.
