Overview

This is a compact simulation study of an important modeling idea: congestion waves can emerge without a fixed obstruction. The repository provides trajectories, density-flow summaries, and a space-time heat map.

Teaching connection

The project is suitable for advanced students because it links differential equations, numerical simulation, parameter experiments, and careful interpretation. It is deliberately labeled exploratory.

Key findings

  • The experiment demonstrates how local car-following rules can produce system-level waves.

Limitations

  • The scenarios are synthetic.
  • Driver and controller parameters do not establish performance on a real road network.
