After over 30 years of fast economic development and massive construction of
infrastructures, China now owns the largest total length of tunnels in the world. However …

Emergency evacuation in case of an emergency is a crucial problem in high-rise buildings,
as many occupants are in a limited amount of space. To improve building safety design and …

This paper presents evacuation simulations of occupants' flow in a tunnel fire via a modified
cellular automaton model and puts forward corresponding optimized evacuation strategies …

The characteristics of pedestrian movement down stairs from high-rise building influence the
total evacuation time, the formation of congestion and even the safety of evacuees. In this …

To improve the pedestrian outflow in panic situations by suitably placing an obstacle in front
of the exit, it is vital to understand the physical mechanism behind the evacuation efficiency …

This paper presents an enhanced social force model to describe the pedestrian's movement
and evacuation dynamics on stairs. Compared with original models that described the …

Due to the individuals' interactions with the physical environment, pedestrian walking on
various stair-facilities may present different features. Performing controlled pedestrian …

Due to the fact that escape panics are unexpected and dangerous, which excludes real-life
experiments because of technical difficulties and ethical reasons, the evacuation simulations …

Evacuation leaders (individuals guiding the crowd) can make crowd evacuation more
efficient. Selecting their number and positions within the crowd is particularly important when …

In this study, experiments of single-file pedestrian movement were conducted and the
movement parameters of pedestrians were extracted with a digital image processing method …
