Table 1

Relation between the vertex adjacency matrix and the behaviors of region and vehicle.

Vertex adjacency matrix features	Regional behavior	Vehicle behavior
, all	and one-to-one correspondence	Drive normally
, exists	and merge into	Obstructed entry (area in frame , both and are single vehicles)
, exists	Decompose into and	Split (area in frame is a single vehicle); Occlusion separation (occlusion exists in area in the frame )
