Abstract: Pedestrian evacuation with guidance is investigated by a multi-grid model in this paper. The effects of guider type, guider number, guider distribution and guidance strategy on evacuation are discussed. From the analysis of simulation results, it is found that the identified guiders are more beneficial to evacuation because they can be distinguished easily by pedestrians during evacuation, The optimal guider number exists in view of the human cost and can be obtained in our model, The uniform distribution of guiders covers more area in the room and makes evacuation efficient, Evacuation guidance is more effective when the speed of guider is about 75% of herding pedestrian's speed in our simulation scenario, The performance of evacuation guidance strategy considering both distance and occupant number is the best when compared to other strategies, The coordination and cooperation between guiders are very important and necessary to facilitate the evacuation. The study may be useful for understanding the importance of guidance in evacuation and developing efficient evacuation strategy for management under emergency. (C) 2015 Elsevier B.V.
