Corridor width does not match target

[Anonymous]

Dear friends,

I have been working on a road project abut I am down with a problem that I tried to solve for these two days but could not find an answer yet.

I designed a road of 8200 m and the road alignment has nearly 30 curves. Road width is 10 m (composed of two lanes with 3.75m lane width and 1.25 m shoulder width.) WB20 type vehicle will move on this road hence I need to apply widening for curves. I use offset alignment command to create target offsets. This is how I define alignment offsets.

Then I create an assembly with "Lane Outside Super With Widening" because corridor width will increase at curves. Hence, I set targets for the assembly while creating the corridor.

However, as a result, after the corridor is created, lane sides do not match the target lines as below. What is the problem with the mpodelling?

Could the issue be with the sub assembly calculation of widening taking precedence over the target width alignment?

I don't know what the problem is. In fact I am nıt sure about the logic that sub assemly calculates widening? Can you explain a little bit and tell me about the possible solution?

How does sub assembly calculates the widening? Do I define something wrong?

This is what i was looking at http://docs.autodesk.com/CIVIL/2010/ENU/AutoCAD%20Civil%202010%20User%20Documentation/index.html?url...

Ok I solved the problem. It was due to assembly type. It is true to use lane outside super assembly. In such case, no extra widening is done by the program itself and the target line matches the corridor.

Thanks for your help.
