Daily.
The slower traffic keeps to the right. Cyclists split the path and maintain directional flow in either direction. Cyclists tend to ride quite fast. (I know I have done 16.2 MPH average for a 20 mile ride on this MUP... verified by GPS and bike computer.)
As far as well occupied... I am not sure what qualifies as "well occupied..."
Occasionally a dog doesn't follow the rules... but then they do that in streets too.
