Simulator measures the influence of people on AGVs using Social Force Model

Social Force Model

The Social Force Model (SFM) is a mathematical model used to describe the movement of individuals in crowded spaces. It was first proposed by Dirk Helbing and Péter Molnár in 1995.

The model assumes that individuals move based on two types of forces: physical forces and social forces. Physical forces are those that are governed by laws of physics, such as inertia, friction, and gravity. Social forces, on the other hand, are those that are influenced by the behavior of other individuals in the crowd

The SFM model also takes into account the personal preferences of individuals, such as their desired walking speed and preferred direction of movement. These preferences are included in the model as parameters that can be adjusted to simulate different scenarios.

Throughout the years, many improvements were made to the original model. One of the latest improvement was made by Moussaïd et al. (2009). In their research, the model parameters were calibrated to match the results of the experiment they have conducted on the real-world crowd. This simulator is created based on this research.
