Black-hole analog in vehicular traffic

TL;DR

This paper introduces a novel black-hole analog in vehicular traffic, using the propagation of tail light flashes to illustrate causal diagrams, bridging concepts from general relativity and traffic dynamics.

Contribution

It presents a new black-hole analog in traffic flow and demonstrates the application of causal diagrams from relativity to traffic modeling.

Findings

Causal diagrams can model traffic flow phenomena.

Tail light propagation creates a black-hole analog.

Illustrates interdisciplinary application of physics concepts.

Abstract

We propose here a simple black-hole analog in vehicular-traffic dynamics. The corresponding causal diagram is determined by the propagation of the tail light flashes emitted by a convoy of cars on a highway. In addition to being a new black-hole analog, this illustrates how causal diagrams, so common in general relativity, may be useful in areas as unexpected as vehicular-traffic dynamics.
