GOYO GRZESKOW: In this video, we will explore InfraWorks Traffic
00:03
Simulation tool to analyze, and design our road and highway
00:06
projects.
00:08
This is where we are at the analysis in civil engineering
00:11
learning path, right at the start.
00:14
There are two different traffic simulation interfaces
00:16
within InfraWorks, you have the basic tool, the traffic
00:19
simulation preview, and you have also
00:22
a more advanced tool called, traffic analysis panel.
00:27
In InfraWorks, you will find Traffic Simulation
00:32
within the InfraWorks analyze tab,
00:35
under the transportation panel.
00:38
If you cannot see the traffic simulation icon straight away,
00:41
simply click on the panel's drop-down menu to find it.
00:45
If you wish to have the traffic simulation
00:47
icon within the panel toolbar, select the three dots
00:50
option to the right of the traffic simulation line,
00:54
and pin to the toolbar.
00:56
If there are already exist in traffic study areas
00:59
within the model, once we select a traffic simulation icon,
01:03
the preview tool will automatically
01:04
zoom in to the latest modified area on the model.
01:08
The traffic study areas are delimited by a red dashed line,
01:12
and blue boxes called zones, which
01:15
are the points from which, and to which, vehicles move,
01:18
determined by the in an out demands.
01:22
Something important to notice is that, in order
01:24
to create a traffic study area, we
01:26
will need to have at least one intersection within it,
01:29
composed by two component roads.
01:32
If we zoom out, and there are more traffic study areas,
01:36
we will recognize them by the traffic simulation
01:38
icon, projected on the terrain.
01:40
If I hover over the icon, a tool will be displayed
01:43
with the most relevant data--
01:45
name, area value, number of valid roads, intersections,
01:49
and zones.
01:51
In this particular traffic study area,
01:53
we will see only two zones.
01:55
Why the perpendicular road does not
01:57
have another two zones like in the previous example,
02:01
that is because the perimeter of the traffic study area
02:04
is too close to the intersection.
02:06
Bear this in mind, when using the tool.
02:09
Let's focus now on the Traffic Simulation preview window.
02:14
If you accidentally close the window,
02:16
simply right-click on any area of the canvas,
02:19
and select asset card to recover it.
02:21
On the top of the window, we have
02:23
the name of the traffic study area selected,
02:25
which we can edit.
02:27
Then the analysis display options, result volumes,
02:30
and delay threshold.
02:32
Below it we can see a drop-down menu,
02:34
containing the predefined simulations we are able to run.
02:38
And finish the simulations previously ran,
02:40
and the results.
02:42
Lets use a presimulated one.
02:46
By clicking on the Play icon of one
02:49
of these pre-run simulations, for example
02:52
the one called quick simulation, the animation player displays.
02:57
On it, we can see different speeds on a time line below.
03:02
If we press play, the vehicles will
03:04
start to appear within the traffic study
03:06
area moving between zones.
03:15
If we want to run a simulation that is not on the results,
03:19
you can select one of the simulations
03:21
available on the drop-down menu, and then
03:23
click on Run simulation.
03:26
Once we process it, it will appear in the results,
03:29
and we can play it as we did with the previous one.
03:32
Notice, the timeline has also changed.
03:35
We did traffic simulation preview two,
03:37
we can easily understand if the lanes
03:39
queue is over passing the delay threshold of our choice.
03:43
This information gives us valuable references
03:46
to guide our designs.
03:52
If we are flexible with the waiting time,
03:55
we have the ability to edit the threshold.
04:00
We can also change the result volumes to have them,
04:04
per approach, per lane, or off.
04:09
So, as you see, this tool only allows
04:12
us to run by the full simulations, which
04:14
means that the rules governing the behavior
04:17
of the intersection, and the vehicles being displayed
04:19
are predefined parameters.
04:22
You will not be able to edit those parameters
04:24
from the Traffic Simulation preview window, however,
04:27
it will be able to do so, and add new simulations,
04:31
when using the traffic analyst panel.
04:34
If you right-click in the canvas,
04:36
you will see the option of the traffic analyst panel.
04:40
Select that option to open it.
04:43
Note that you will be only able to open the traffic analyst
04:46
panel once a traffic study area has been defined, not before.
04:51
The Traffic Simulation panel is an advance simulation tool
04:54
for vehicles moving on a network of roads.
04:57
With this tool, we can edit demands, profiles, timing,
05:01
vehicle types, intersection details, lanes, parameters,
05:05
et cetera, for new or existing simulations.
05:09
We can then synchronize these simulations,
05:11
and have them ready for the InfraWorks traffic simulation
05:15
preview tool.
05:17
We will explore in depth the practical capabilities
05:19
of the traffic simulation panel on our upcoming videos.
05:24
For now, and before we run our first step-by-step simulation
05:27
on the next video, let's load the data set that
05:30
has been shared with you on the welcome page, and make sure
05:33
the setup is well done.
05:35
If you haven't downloaded the R&H conceptual design zip
05:39
file, please do it now.
05:41
Once you have extracted the content of the zip file,
05:45
you should have a folder called R&H Conceptual.files,
05:50
and a couple of files.
05:53
One called RoadCleared.imx, and the other R&H Conceptual.sqlite
05:60
file.
06:02
Starting from the InfraWorks homepage,
06:04
we will open the file that contains the model.
06:07
Please, select, and open the sqlite file mentioned before.
06:17
You will see, that we have the development proposal
06:20
I shared in previous courses.
06:23
As usual before editing, create a new proposal
06:26
we can call PL1_local, which has to be based on the road design
06:33
proposal.
06:36
In this particular case, we'll need
06:37
to clean up the model where the road was displayed,
06:41
and define the way to avoid errors when analyzing.
06:44
In order to ease this task, I have shared with you
06:46
the RoadCleared.imx file.
06:49
But before inputting it, we are going
06:50
to delete the resources that are not related, nor needed,
06:54
for this course, so that our model is more agile,
06:58
and there are less elements to be regenerated.
07:01
For the same reason, I would also
07:03
recommend you to switch to the engineering view
07:05
when designing, or analyzing.
07:08
Remember that we can safely delete elements,
07:11
as we have created a parallel proposal.
07:13
Changes made on an active proposal
07:15
are not affecting all the proposals.
07:18
If we realized later that we have deleted too many items,
07:22
there is always a way back.
07:24
In this case, we will remove buildings
07:26
that are not part of the proposed development,
07:29
the coverage area folder, the railway folder, the roads
07:34
folder, the water areas folder, and only
07:38
after importing the imx, I'll also
07:41
remove the original sources from the terrain folder.
07:44
When importing the imx files, make sure
07:46
that all the sources are checked.
07:49
Once they are under the data source area,
07:52
right-click to configure.
07:55
Go to the Source tab, and on the draping options
07:59
select drape, close, and refresh.
08:06
If this message appears, open the surface layer panel
08:10
to put the layers of the sources we have just
08:13
imported under the ground surface layers.
08:18
Click Apply, and OK.
08:23
Once we've done that, let's remove the elevations that were
08:27
part of the previous terrain.
08:30
The reason we cannot see the terrain now is because we
08:33
didn't switch on the ground surface layers we imported
08:36
before.
08:38
Once we switch them on, click Apply, and OK.
08:42
They will be displaying correctly.
08:45
Remember that in order to run a traffic simulation
08:48
in InfraWorks, you will need to have the model extents defined,
08:53
an intersection, and two component roads defining
08:56
the intersection.
