This is something that comes from Google Now, so it comes from your oh phone. I think you can tell Google Now to stop showing this kind of information (travel times and directions) but you'll have to do it in the Google search app on your phone. I think there is also a way to block notifications from certain apps so that they don't show up on your watch, but then all notifications form that app are blocked. A lot of people complain about the amount of notifications that Google Now sends, so hopefully Google will address this issue some day
