Why was displayed error?

Look at the properties for the alignment, particularly the Design Criteria tab. 

In this case you probably have superelevation transitions which are not long enough for the standard you are using.

As a side issue; posting a question without a descriptive subject line makes it more difficult for people who might help you to find your post.  Please try to include more information about your problem in the subject line next time.  It is also very helpful if you include information about which version of the software and what operating system you're using.

Regulations "AASHTO 2001":
When the speed of 110 kilometers per hour, AND , radius="560" In this case, tLength="53" (for 2 Lane)

And the value 53 is assigned by the CIVIL 3D

My problem is not resolved 

In video "https://www.youtube.com/watch?v=x2zSnQPndQY", there is the problem

But I do not understand what to do

Please Help Me

I don't have the AASHTO 2001 file on my system, so I cannot reproduce the error.  Perhaps someone else can help.

Your rate of change is causing the issues.

Select your super elevation view, right click and select Open Tabular Editor.

In the Superelevation Tabular Editor between the "Left Outside Shoulder" column and the "Curve Smoothing(LOS)" column you should notice two vertical red lines, where most of the other seperators between columns are only a single red line. The double red lines means there are columns that are hidden.

Move you mouse over the line seperating the column headings for "Left Outside Shoulder" and "Curve Smoothing(LOS)" and the mouse icon will change to a verical line with an arrow pointing left and right. Left click the column dividing line and drag it to the right. A column should appear titled "Rate of Change(LOS)"

If you scroll down now, you should see the warning triangles in the "Rate of Change(LOS)", next to values of -0.114 and 0.114, which I believe from looking at the road design standards file provided with civil 3d, exceeds the rate of 9.2 (guessing the 0.114 translates to 11.4 as opposed to 9.2).

So you need to stretch your super development lengths, or ignore the errors.

You will find that there are 3 more hidden columns in Superelevation Tabular Editor, all of which are your Rate of Change columns and all showing check violations.

It would be extremely usefull though if the error notification you first posted showed what was being violated.
