Answer:
linear perspective
Step-by-step explanation:
A linear perspective is a system for creating an illusion of depth on the flat surface. Here the parallel lines drawn using the linear perspective converge into a single point and vanishes at that point on the horizon line of the composition.
In the context, there occurred a railroad accident where the car driver could not estimate the train distance as the parallel track of the rails stimulated a monocular depth because of linear perspective system of view.
