PSO-Based Emergency Evacuation Simulation
نویسندگان
چکیده
The Emergency Evacuation Simulation (EES) has been increasingly becoming a hotspot in the field of transportation. PSO-based EES is a good choice as its low computation complexity compared with some other algorithms, especially in an emergency. The selection of fitness function of each particle in PSO is a key problem for EES. This paper will introduce some fitness functions for EES and present a new fitness function called TripleDistance Safe Degree (TDSD). Through theoretical analysis and experimental validation, the TDSD is proved to be much better than other fitness functions introduced in this paper.

Factors Influencing Failure Emergency Evacuation in Work Environments during Fire
One of the necessary measures of saving human life in emergency situations, such as fires, is the safe and swift evacuation of people. The prerequisites for this are to anticipate, identify, and eliminate factors preventing people from leaving buildings in a timely and safe manner while moving them to a safe place [1]. The occurrence of errors caused by engineering, design, human, and psycholog...

متن کاملComparative Analysis and Pedestrian Simulation Evaluation on Emergency Evacuation Test Methods for Urban Rail Transit Stations
The emergency evacuation test method of rail transit station not only affects the operation safety of the station, but it also has significant influence on the scale and cost of the station. A reasonable test method should guarantee both the safety of evacuation and that the investment is neither excessive nor too conservative. The paper compares and analyzes the differences of the existing eme...
متن کاملAgent-Based Emergency Evacuation Simulation with Individuals with Disabilities in the Population
Catastrophic events have raised numerous issues concerning how effectively the built environment accommodates the evacuation needs of individuals with disabilities. Individuals with disabilities represent a significant, yet often overlooked, portion of the population disproportionately affected in emergency situations. Incorporating disability considerations into emergency evacuation planning, ...
متن کاملComputational Framework Incorporating Human Behaviors for Egress Simulations
Studies of past emergency events indicate that evacuating occupants often exhibit social behaviors that affect the evacuation process. This paper describes a multiagent-based simulation framework that enables the modeling of social behaviors during evacuation. Each agent is modeled using a three-level representation that allows users to incorporate individual, group, and crowd behavioral rules ...
