Nowdays, many people move to metropolitan cities like Hong Kong, Beijing, Shanghai, and etc. They visit, work and even live in a crowded city that raises the population density, and the crowded environment may lead to serious safety concerns. To an extreme, fun could turn to disaster, just like the case of Lan Kwai Fong tragic accident took place in 1993, and the deadly stampede occurred in Shanghai at the end of 2014. In our daily lives, we experience the crowed areas in MTR stations, and some sort of pathway and corridor.
In order to visualize the human reaction in the case of emergency in a crowded environment, CityU has developed an agent-based simulation model, which sophisticatedly and realistically reflects the behaviour of real human being. The model is constructed and based on the long-term research work, which is conducted by the university research team (references [1-5]). The aim of this project is to let people understand what can go wrong to the crowded when there is an accident taking place at a crowded place. Then general public and the facility designer can collect the useful ideas suiting their own purposes, namely coping with the unexpected case and designing a safe path respectively.
This simulation model consists of two parts, which are corridor safety and MTR station evacuation. Having learnt through the simulation model, students are expected to realize the importance of both the configuration of the public area and the crowd management by the central when an accident occurs. In addition, they should understand why it is necessary to follow the staff's guidance when it is in need.
