Create a new Mobility Simulation model

00:03

Mobility Simulation is an integrated multimodal mobility simulation engine for InfraWorks.

00:09

One way to use Mobility Simulation is to create animated simulations of pedestrian movement.

00:15

Before creating a simulation, you must create a new model.

00:20

With a traffic study area open in the Mobility Simulation window, from the toolbar, select File > New.

00:27

This opens the New Commuter Model – Parameters Wizard.

00:31

The wizard provides guidance through the creation of a new model.

00:35

However, bypass this for now by clicking Cancel to start with a blank model.

00:40

Orient the new model by clicking the View Cube, and then ensure you are working in Orthographic mode.

00:46

If “Orthographic” is not displaying in your project space, on your keyboard, press the letter O.

00:52

The easiest way to start a basic simulation is to add a walkway and then make some adjustments.

00:59

The two lines that look like an XY axis in the project space are the “cursor” and viewpoint.

01:05

This is where auto components are entered.

01:07

Scroll your mouse wheel, and notice the values of the cursor change.

01:12

This Zoom value can change from 2 to Infinity, representing the height of the viewpoint, in meters, above the ground plane.

01:19

Once the Zoom value is set to around 30 meters, right-click and select Walkway > New Walkway at Cursor.

01:27

This opens the New Walkway dialog.

01:30

Here, you can specify the name, route class, and measurements of the walkway.

01:36

For now, only adjust the length of the walkway.

01:39

In the Length field, enter “30”.

01:42

Click OK.

01:44

Back in the project window, the new walkway appears and is actively selected, with relevant data also displayed.

01:52

On your keyboard, press ESC to deselect the walkway.

01:57

The walkway now appears as two vertical lines.

02:01

This is not enough to physically manipulate the model, so the next step is to turn on some layers.

02:07

Zoom into the walkway and, from the Tabs panel, open the Layer tab.

02:12

The Layer tab is a two-dimensional table of colored toggle buttons.

02:16

Named layers are listed down the left-hand side, and numbered aspects are displayed along the top.

02:22

A Layer is a group of objects of the same type, like Lanes, Signs, or Crossings.

02:29

Each Layer can be switched on or off in any Aspect by pressing the toggle button.

02:34

You can also change the color of any Layer in any Aspect by right-clicking the button.

02:39

Select the first Aspect column, 0 - General, and enable Walk Centerlines.

02:45

Next, enable Walk Connections.

02:48

While walk connections are not necessary for simple models, it is best practice to always enable it.

02:54

Then, enable Handle – End and Handle – Other.

02:57

With these layers configured, you can now manipulate the walkway.

03:01

In the project window, select the walkway with the middle mouse button.

03:06

Now, you can pick the walkway and move its position.

03:10

This process also applies to the end handle of the walkway.

03:13

Pick and move the end handle to change the angle of the walkway.

03:17

Creating new models and placing walkways in InfraWorks Mobility Simulation

makes it possible to simulate pedestrian movements through environments.
