Create a traffic simulation model in InfraWorks

00:03

In InfraWorks, you can create a traffic simulation, which allows you to view and analyze traffic flows along roads,

00:11

intersections, and roundabouts.

00:14

Begin by opening an InfraWorks model with planning roads already converted into component roads,

00:20

and with a defined traffic study area actively selected.

00:25

From the Traffic Study Area panel, under Analysis Display, you can set the result volume information for your simulation.

00:33

This lets you configure demand parameters for traffic to and from the demand zones within the model.

00:40

For this example, under Analysis Display, set Result Volumes to Per Approach and set the Delay Threshold to 20 seconds.

00:49

With the result volume set, color-coded queue lengths based on demand will be added to the traffic study area when you run the simulation.

00:58

The color represents the delay time.

01:00

Queues appear red if the delay exceeds the threshold you set, visually warning you if there is a problem with traffic queuing in that area.

01:09

Now, run a quick simulation.

01:12

Still in the Traffic Study Area panel, under Simulation, expand the Simulations drop-down.

01:19

Here, you can choose from pre-built simulations.

01:22

For this example, select Quick Simulation.

01:26

Then, click Run Simulation to create a traffic flow animation file.

01:31

Keep in mind that this can take some time.

01:34

A loading dialog appears, reporting progress, as InfraWorks prepares the Mobility Simulation equivalent of your model.

01:41

When the analysis is complete, the Animation Player lists the animation with a status of Ready.

01:48

To view the traffic simulation animation, click Play.

01:53

You can adjust the speed of the animation as needed using the speed buttons.

01:57

Zoom in to the model for a better view.

02:00

In this example, there is not a lot of traffic activity, because the pre-built simulations are configured with relatively low demands.

02:08

Zoom further into an intersection, if necessary, to see the color-coded queue lengths based on demand.

02:16

As you have seen, viewing custom traffic simulation animations

02:21

allows you to understand and predict the traffic flow patterns in your InfraWorks model.
