In this paper, two important factors which affect the pedestrian outflow at a bottleneck significantly are studied in detail to analyze the effect of an obstacle setup in front of an exit. One is a conflict at an exit when pedestrians evacuate from a room. We use floor field model for simulating such behavior, which is a well-studied pedestrian model using cellular automata. The conflicts have been taken into account by the friction parameter. However, the friction parameter so far is a… 
Study on Efficiency of Evacuation with an Obstacle on Hexagonal Cell Space
The authors of this paper have found that putting an obstacle in front of an exit in a congested situation increases the pedestrian outflow, which is the number of pedestrians going through an exit
A modified universal pedestrian motion model: Revisiting pedestrian simulation with bottlenecks
TLDR
The four parameters that are most critical for physical interactions of the social force model are identified and then calibrated against two well-controlled pedestrian experiments and indicated that the effect of the exit location on the pedestrian egress efficiency is uncertain, and the evacuation efficiency is also related to the exit width and the level of urgency.
The effect of moving obstacle on regulation of pedestrian flow in a single exit room
One of the key problems for crowd management is to improve the evacuation efficiency of pedestrians. In this paper, we study pedestrian evacuation from a single exit room based on a social force
Pedestrian evacuation simulation in the presence of an obstacle using self-propelled spherocylinders.
TLDR
This work simulates a system of nonsymmetric spherocylinders that have a prescribed desired velocity and angular orientation and reproduces the nonmonotonous dependence of the pedestrian flow rate on the obstacle distance to the door.
Effects of an Obstacle Position for Pedestrian Evacuation: SF Model Approach
TLDR
The dynamics of pedestrians are investigated and the effect of a disk-shaped obstacle with various sizes placed in several positions via numerical simulations for a social force model is clarified and an “optimal size” of an obstacle is determined.
The Impact of an Obstacle on Competitive Evacuation Through a Bottleneck
TLDR
Whether an obstacle can improve the flow rate passing through an exit is dependent on the surrounding geometry, as demonstrated in this study.
Nonlinear effects in examples of crowd evacuation scenarios
TLDR
A new microscopic agent-based pedestrian model is developed and simplified evacuation scenarios which permit the isolation of relevant nonlinear effects and their systematic investigation are studied, indicating the existence of unstable pedestrian flow states in addition to the stable states.
Simulation of pedestrian evacuation based on an improved dynamic parameter model
An improved dynamic parameter model is presented based on cellular automata. The dynamic parameters, including direction parameter, empty parameter, and cognition parameter, are formulated to
