Abstract EN
Pedestrian evacuation dynamics in a classroom is always a complex process influenced by many fuzzy factors.
It is very difficult and inappropriate to quantify the impact of these fuzzy factors by using the mathematical formula.
Existing microscopic simulation models have made many efforts to use accurate mathematical method to model the fuzzy interaction behaviors between pedestrians under the view-limited condition.
This study tries to fill this gap by establishing a microscopic simulation model which can represent the fuzzy behaviors of pedestrians under view-limited condition.
The developed fuzzy social force model (FSFM) combines fuzzy logic into conventional social force model (SFM).
Different from existing models and applications, FSFM adopts fuzzy sets and membership functions to describe the pedestrian evacuation process.
Seven fuzzy sets are defined for this process, such as stop/go, moving direction, desired force, force from obstacles, force from pedestrian, force from indicators, and acceleration.
Membership function of each input factor is calibrated based on the observed data.
Model performance is verified by comparing speed distribution, velocity-density relationship, and results of simulation and observation evacuation time.
Besides, the proposed model is applied to assess the number and space distribution of exit indicators and stickers.
By comparing simulation results with existing models, the paper concludes that FSFM is able to well reproduce pedestrian movement dynamics in real world under view-limited condition.
