Configure people demands for a train network in InfraWorks Mobility Simulation

00:03

In InfraWorks Mobility Simulation, once a train network is properly configured with stands, scheduled service,

00:10

and pedestrian walkways, you are ready to add people.

00:14

You define the number and location of pedestrians added to a simulation model using people demands.

00:21

Begin in an open InfraWorks Mobility Simulation model with a completed train network.

00:27

To set demands for passengers being picked up and dropped off by the scheduled service, select Demand, and then click Demands.

00:36

The Demand Editor dialog appears.

00:39

Here, click New to create a new matrix where you can add passenger volume to the train network.

00:45

For this example, the default name Matrix1 is used.

00:50

Click OK.

00:52

Back in the Demand Editor dialog, you see that in Matrix1, there is currently no pedestrian data.

00:59

The train service in this example runs in only one direction, meaning you only need to set demands for the beginning of the train route.

01:07

In the matrix, click the first cell of column 2, and in the model, a yellow arrow indicates the direction of demand for that cell.

01:16

To add 200 pedestrians traveling from the lower pedestrian area to the upper area, enter 200, and then click OK.

01:25

You can create different views to change visual perspectives as the multimodal simulation animation runs.

01:32

First, orient the model to a view of the first train stand.

01:36

Then, in the Tabs panel, on the View tab, click New.

01:41

The Name for View dialog appears.

01:44

For this example, use the name “Pickup” to represent where passengers board the train.

01:50

Click OK.

01:52

The Pickup option now appears in the View tab.

01:55

Repeat these steps to create 2 more views.

01:59

Again, reorient the model, and this time, choose a perspective of the entire train network.

02:05

Name the view “Overview”, and click OK.

02:09

Create a final view to watch passengers exit the train, and name it “Setdown”.

02:16

Select Overview to return to the full view.

02:20

Now, create and run a simulation.

02:23

In the Tabs panel, select the Simulation tab, and click New.

02:28

For this example, Simulation is the default name.

02:32

Click OK.

02:34

Select Simulation, click Show (the light bulb) to make it the current view, and then click Play.

02:41

With the simulation running, you see the train moving, people arriving at the boarding area, and people exiting the train at the second stand.

02:50

For different perspectives, use the views you just created.

02:53

Click the View tab and select Pickup to view people arriving along the mapped pedestrian streams

02:59

and queuing to be picked up by the scheduled train.

03:04

Select Setdown to watch passengers exit the train service at the end of the network.

03:11

Select Pickup to return to the boarding area view, and then zoom in.

03:16

Notice that people in the animation are only queuing at 4 out of the 10 doors.

03:21

That is because only 4 doors were specified when the train service and transport type were configured.

03:28

Again, click Setdown to see passengers also leaving the train through only 4 doors.

03:35

Finally, select Overview to see the entire train network in action,

03:39

driven by the people demands you just configured in InfraWorks Mobility Simulation.

03:44

While this example of a multimodal simulation combines only a train and some people,

03:50

you can use this process to combine many different modes, including cars, bicycles, taxis, and buses, for a more advanced simulation.
