Simulations

Definition

Simulations are virtual representations or models that mimic real-world systems, processes, or environments to study their behavior under various conditions. They are crucial in developing and testing collision avoidance systems, as they allow for safe experimentation with different scenarios, including unexpected obstacles, varying weather conditions, and human interactions without the risk of actual accidents.
