Is html 5 <!DOCTYPE html> equivalent to html 4 transitional doctype?

If I set the doctype to the HTML 5 <!DOCTYPE html>, this will set browsers into standards mode.

Does that mean that most modern browsers will behave as if they are in HTML 4.01 Transitional mode?

Browser's don't actually have a "HTML 4.01 Transitional mode". They have a "standards" mode and historic modes, "quirks" and "almost standards" for most browsers, and a variety of earlier IE behaviours for IE.

There isn't a direct mapping from a "HTML 4.01 Transitional" doctype to a mode, but for most modern browsers, it maps to "almost standards" mode in the presence of the SYSTEM identifier and "quirks" mode in its absence.

For more details, see http://hsivonen.iki.fi/doctype/ and http://dev.w3.org/html5/spec/tree-construction.html#the-initial-insertion-mode

No these are not similar. Though HTML 5 Doctype is still a draft. But if you will validate your code on HTML 5 compliance check, it will not support the deprecated html 4 attributes or tags. Also, the new HTML 5 tags will only be supported in HTML 5 doctype when you are validating your code. You can validate it at this link: http://validator.w3.org/

It means the browser will be in standards mode as opposed to quirks, which is the only real distinction to be made unless you're concerned about a specific kind of validation for some reason. Strict was only interesting in the context of making an html document adhere to xml standards, which HTML5 doesn't follow.
