a r t i c l e i n f o It is an important issue that all occupants should be able to evacuate to safety from large public buildings under fire conditions. In this paper, a system simulation model is presented, in which a physical model and a mathematical model are included. Based on the agent technology, a computer program is developed to simulate and(More)
The correct and quick evacuation of occupants is very important for the save of lives in a public building when it is attacked by a fire. However, it is difficult to train the occupants for evacuation in a real environment since it is dangerous and expensive. This paper presents a virtual reality system developed by the authors for the simulation of(More)
To improve spatial descriptions in evacuation model, this paper establishes an analysis process for variable distributions in 3d continuous space. The features of distributions were captured to simulate spatial cognition and way finding for occupants. Evacuation strategies including follow, walk-aside, crawl and crossover were designed accordingly and a(More)
Vehicle population is in a period of rapid growth in China, while the problem of traffic safety is growing and road traffic deaths remain high. Traffic safety education is playing an important role in improving the awareness of road safety, prevention and reduction of road traffic injuries. Video and audio teaching materials are attractive and appealing to(More)
In order to be safely used in the 2008 Olympic Games, the currently existing gymnasiums should be taken for evaluating their safety of utilization. As the structural analysis and fire simulation have been developed to work separately in previous works, the normal loads and fire actions have not been able to be taken into account together.
