Using the space-time cube to show the track data storage model
of a moving vehicle object is to describe the mobile changes of a vehicle object in a spatial location.
According to the characteristics of a moving vehicle object, the space-time cube model is mainly
constituted by points, track, space division, events and unit elements of the space-time cube. A point (x, y,
z) in the cube is an abstract expression of the spatial location of a moving vehicle object at a certain time.
The continuous moving of a point forms a track, which is a set of points, and reflects the movement of a
moving vehicle object during a period of time. A space division can be formed through the ground space
