In this unit we explore models and other ways to analyze the safety of a building and evaluate which elements may affect how quickly and safely a space may be evacuated. Among the questions we will ponder are:
- How do people move in crowded situations?
- Why should a building have multiple exit routes?
- How do people react to emergency situations?
- What difference does it make if the building is familiar or new to the people in it?
- What are the similarities/difference between evacuating a building and evacuating an outdoor concert?
Unit Overview - for more details see Pacing Guide
Lesson 1: Introduction to Emergency Egress.
- Battle of the Agents activity
- Battle of the Agents StarLogo Nova base model and possible solution
- Video: The Floor Plan
- Emergency Egress Base Model and possible solution
Lesson 2: Adding agents and giving the agents behavior under certain conditions.
Lesson 3: Introduction to the concept of Floodfill.
- Video: What is Floodfill?
- StarLogo Nova model demo: floodfill
- Pennies egress activity (see link below)
- Modify model by adding "placers" at exits. Possible solution
Lesson 4: Add a smart behavior to the agents to be aware of the exits and to use the floodfill pattern to exit. Students will measure the time it takes for agents to exit with or without a plan.
- Video: exiting the building in case of emergency
- Walking speed activity (see Pacing Guide Lesson 4)
- Use CAST to evaluate emergency egress (see link below)
- Modify model to add an exit plan to agents' movement. Possible solution
In Lessons 5 and 6:
Use Experimental Design Form and Project Design form to examine additional behaviors, such as the maximum capacity under strict time limits to exit the building; alterations to the floorplan such as adding more exits or exit size; confusion/panic in the agents, adding agent/agent interaction (collisions); or limited visibility (smoke).
