This puzzle is a variant of U-Bahn with empty cell clues, which originates from a series by KNT.
If you are unfamiliar with U-Bahn, here is a guide that covers the core logic.
Draw a loop network through the centers of some cells, which may branch or turn, but may not have any dead ends.
A clue outside the grid indicates in how many cells the corresponding behavior (i.e. turn, straight line, branch, cross, or unvisited) occurs in the row or column, irrespective of rotation.
