Street recognition in Wikitude Drive

Hi, I'm new to Wikitude but not to AR, so I'm exploring Wikitude capabilities and functionalities.

I just discovered there is an AR navigation app for Android, namely Wikitude Drive, I suppose based on Wikitude library. In this application a line is drawed on the street suggesting the correct way to follow, like in the following screenshot.



I was wondering about how Wikitude Drive do this: Image Recognition of the ground, or simply by the current position and device orientation?

Thank you.
