Simulating crowd behaviour in an emergency situation
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
In this thesis we have tried to simulate a crowd of humans in emergency situations. Based on previous research we have implemented a system that simulate human crowds in emergency situations. In this system each crowd member (called agents) is affected by forces from the surrounding environment which direct the movement of each agent. The forces can be either real physical forces or they can be psychological forces that represents humans tendency to stay a certain distance from inanimate obstacles and other crowd members.
In our system the crowd can consist of different populations separated by average values of the properties each agent in the crowd has. The properties are easy to modify and are used as a way of modeling individuality for each agent. Changing properties changes the outcome of a simulation. The results are saved in a file that can be used for further analysis.
Our most important result is that we have been able to use our system to make conclusions about real life crowd behaviour and also seen crowd effects in our simulations that are apparent in real life. Some of the results shows that in crowds where people try to help each other escape more people will survive. A crowd effect observed is arch like formations around doors. These formations breaks which let some people escape then the arch reforms and the pattern is repeated. This is particularly visible when the average speed of the crowd members is high.
Our system still lacks some functionality which would allow easier use of the system and more accurate simulations.
