Discover Traffic Simulation advanced options (5:14 min)

00:01

GOYO GRZESKOW: In this video, we will

00:03

discover what are the advanced options we can modify

00:06

in traffic simulation to analyze and design our road and highway

00:10

projects.

00:11

This is where we are on the overall field

00:13

of the Analysis in Civil Engineering Learning Path.

00:17

Back in InfoWorks, on the R and H conceptual model,

00:21

I'm starting on the PO2 proposal created on the previous course.

00:25

I'll switch to the PO1 local planning reporter

00:29

and then to the engineering view.

00:31

We'll select the traffic simulation option,

00:34

and focus on the TSA 3, or traffic simulation

00:38

area 3, the east intersection.

00:41

Actually, we are going to create a bookmark for this area.

00:46

Let's check the zone demands for TSA 3.

00:49

Note that the in and out demands display the demands related

00:52

to the active simulation, quick simulation,

00:55

but when switching to long morning simulation,

00:58

we can see how the in and out demands change,

01:01

when hovering over the zones.

01:03

We can easily relate the zones within our TSA

01:06

to the cardinal points by looking at the view.

01:10

Let's run a quick simulation, and then

01:12

open the tab, the traffic analyst panel,

01:16

to dive into its advanced options.

01:18

Initially, you should be able to see the model imaginary TSA 3.

01:23

On the right-hand side menu, you can see five tabs--

01:27

view, layer, action, analysis, and simulation.

01:30

The Simulation tab displays whole simulations

01:33

we can see within traffic simulation preview

01:35

back in InfoWorks.

01:36

Below, you will see the components of the simulation.

01:39

The active simulation is grayed out,

01:41

and in order to change the active simulation,

01:43

we need to select and click the bulb icon.

01:47

If we zoom in TSA 3 and we start the active simulation,

01:50

we can observe the level of detail, which can

01:53

be changed under the View tab.

01:57

On the top of the View tab menu, we

01:59

will find the bookmark fields within tab, traffic analyst

02:03

panel.

02:04

In this case, the View one is an already existing view.

02:10

If you check at the bottom, we have three very important

02:13

dropdown menus.

02:14

The middle one adjusts the level of detail.

02:19

The right-hand side one allows to adjust

02:22

the speed of the simulation, and the left-hand side one

02:26

allows to disable the addition of tab elements.

02:32

The next tab is the Layer one, which

02:35

give us the chance to control what is being displayed.

02:39

For clarity, I will hide the image of the surface and also

02:43

the cursor.

02:49

After finishing to set up according to your preferences,

02:52

press Sync to save the changes for future tab openings

02:57

on the top-left corner under the Cloud tab.

02:59

The next tab in row is the Actions one,

03:02

which sets the tab using different options.

03:06

And to finish, the Analysis tab, which display different data

03:10

views related to the active simulation being run.

03:13

Among all this, you can see the current vehicle count in

03:16

or the intersection level of service.

03:19

Back on the Simulation tab, when reactivating quick simulation,

03:22

in this case, we can observe that it

03:24

last 10 minutes, which is the time specified

03:27

for that simulation.

03:28

Hence, the AM10 parameter.

03:31

And AM180 will mean a three-hour simulation.

03:36

TAP has the capability of running

03:39

a maximum of

03:41

so that no matter how long our simulation is,

03:44

it will stop after 30 minutes.

03:46

This does not occur on the traffic simulation preview.

03:49

Back in InfoWorks, the whole length of the simulation

03:52

is displayed.

03:54

We'll now quickly create a new 5-minute simulation.

03:59

For that, we'll create a new AM05 parameter and a new AM05

04:05

demand.

04:06

The AM05 trip will be automatically created

04:10

after having the previous two.

04:12

Then, we will create the simulation, GGSIM.

04:16

In order to edit our components, the new simulation

04:19

must be active.

04:26

We can then edit the demand metrics, and also,

04:31

the time frame of our simulation,

04:33

adjusting it to five minutes.

04:37

After adjusting accordingly to our needs,

04:40

we needed to sync the component changes to the simulation

04:44

table, and then we can run the simulation.

04:49

Note that the below message appears

04:51

because of the lights and the speed limit

04:54

at the intersection.

04:55

Those parameters constrain the number

04:58

of trips scheduled on the demand matrix.
