Set targets for corridors

00:05

In this video, we're going to further refine our corridor by assigning our targets,

00:10

and by setting the frequency of our assemblies inside of our corridor.

00:14

In order to do that, we're going to navigate over to the Prospector tab,

00:17

we're going to go down to our Dev-Cor, we're going to right click and we're going to go to Properties.

00:22

Inside of properties, we're going to go into parameters and this is where we have our baseline and region sections.

00:27

So inside of our baseline and region sections, if we go and we select Set all Targets,

00:34

inside of here it has all of the targets associated with certain sections inside of our corridor.

00:41

So we have the Dev-Cor and assembly names.

00:43

I don't prefer to do an all-in-one shot because I don't want to accidentally set the wrong target.

00:49

So what I'm going to go ahead and do is I'm going to set my baselines one at a time.

00:53

So I'm going go to my baseline for my main corridor, not the Cul-de-sac,

00:57

I'm going to go over to my targets and I'm going to click the ellipses associated with my Dev-Cor, Dev-Target.

01:04

I'm going to set my target surfaces as EG.

01:10

I'm going to set my width or offset targets as my offset alignments.

01:18

And so as you can see, my transition alignment is set to right.

01:22

So what I need to make sure I'm doing is selecting my Dev-Align-Right, and clicking ''Add'' and then clicking ''OK''.

01:29

And then same thing here for my left, I need to make sure I'm choosing my Dev-Align-Left, clicking ''Add'' and clicking ''OK''.

01:38

Moving on to slope and elevation targets, we have our basic lane transitions for right.

01:44

So I'm going to go ahead and set my right to my Dev-Align-Right, and click ''OK''.

01:53

And then I'm going to select my left, dropdown, Dev-Align-Left, ''Add'' and click ''OK''.

02:01

So I've now set all of my targets for my Dev-Cor, Dev-Target region.

02:07

Now I'm going to move on to my baseline for my Cul-de-sac and I'm going to set my targets.

02:11

And so my surface targets are going to be EG.

02:15

My width and offset targets are going to be, this is going be interesting because we are going to be targeting the dev-alignment,

02:23

because the dev-alignment is in the center of that corridor or in the center of that cul-de-sac.

02:29

So I'm going select 'Dev-Align, I'm going to select ''Add'' and I'm going to go ahead and click ''OK''.

02:34

And then for my slope or elevation targets, I'm going to go ahead and select my Dev-Align profile,

02:42

and I'm going to select my Dev-Align profile, and click ''Add'' and then I'm going to click ''OK''.

02:47

And then I'm going to finally click ''OK'' to accept all of those targets.

02:51

Now I'm going to move into frequencies.

02:53

So inside of my frequencies for my main baseline, I'm going to select the ellipses here and I'm going to leave my tangent section as the same.

03:01

I don't have spirals, so I don't need to modify that.

03:04

And then my vertical baseline, I could modify that but I'm now going to go ahead and leave that the same.

03:09

The only one that I'm interested in changing is my curve increments.

03:12

I'm going to change my curve increments to 5 because we have some relatively tight curves and I want to capture those curves as well-defined as I can.

03:21

So I'm going to go ahead and set it as 5 and click ''OK''.

03:24

And then I'm going to go to my cul-de-sac and I'm going to set my curve increment to 5 as well, and I'm going to click "OK".

03:31

And when I'm done with that, you're going to see that both of my regions are out of date.

03:36

So I'm going to go ahead and hit ''Apply''.

03:38

Civil 3D is going to ask me to rebuild the corridor, I'm going to rebuild it and I am going to click "OK".

03:44

And when we click ''OK'', what you'll notice is that our corridor is now created with a very well-defined cul-de-sac,

03:53

and every corridor that we go to is now using the targets for the offset widths that we defined and our slopes are targeting our surface.

04:03

So if I go and I click on this corridor now, and I go to the Object Viewer,

04:07

when you look at the Object Viewer, you are going to notice that this corridor is much more refined than the last one that we looked at.

04:16

You're going to see that we have sidewalks that have well-defined curves curving around the corners.

04:22

The transitions are well-encapsulated, where you can see some grading going to the daylight of the existing surface.

04:30

And then when we move into the cul-de-sac, instead of having that jagged, angular cul-de-sac,

04:35

because we changed to 5 foot increments, we now have this well-defined circular cul-de-sac,

04:40

that is correctly targeting the centerline profile of our Dev-Alignment going along the curb line as we hoped it would.
