Crowd Evacuation for Indoor Public Spaces Using Coulomb’s Law

الملخص EN

This paper focuses on designing a tool for guiding a group of people out of a public building when they are faced with dangerous situations that require immediate evacuation.

Despite architectural attempts to produce safe floor plans and exit door placements, people will still commit to fatal route decisions.

Since they have access to global views, we believe supervisory people in the control room can use our simulation tools to determine the best courses of action for people.

Accordingly, supervisors can guide people to safety.

In this paper, we combine Coulomb’s electrical law, graph theory, and convex and centroid concepts to demonstrate a computer-generated evacuation scenario that divides the environment into different safe boundaries around the locations of each exit door in order to guide people through exit doors safely and in the most expedient time frame.

Our mechanism continually updates the safe boundaries at each moment based on the latest location of individuals who are present inside the environment.

Guiding people toward exit doors depends on the momentary situations in the environment, which in turn rely on the specifications of each exit door.

Our mechanism rapidly adapts to changes in the environment in terms of moving agents and changes in the environmental layout that might be caused by explosions or falling walls.
