Constant evacuation time gap: Experimental study and modeling

Abstract: In this paper, the impact of escaping in couples on the evacuation dynamics has been investigated via experiments and modeling. Two sets of experiments have been implemented, in which pedestrians are asked to escape either in individual or in couples. The experiments show that escaping in couples can decrease the average evacuation time. Moreover, it is found that the average evacuation time gap is essentially constant, which means that the evacuation speed essentially does not depend on the number of pedestri… Show more

“…The authors assume that this kind of ordering effect was responsible for the faster ingress with groups. A more recent study [17] also found that pairs can evacuate faster than individuals. Laboratory experiments performed by Bode et.…”

“…The SFM is considered one of the most vital models and is characterized by terms that are capable of formulating and accommodating aspects of crowd dynamics, introducing self-organization phenomena [41][42][43], and reproducing real-life data [44,45]. Extensions of the SFM can enhance the capability for accommodating and controlling various walking behaviors, such as avoiding groups [22,46], penetrating jammed crowds [47] and walking competition [48,49], which are essential factors in comprehending the 'faster is slower' phenomenon [50,51]. The agents in the SFM are self-driven particles, where each agent m is motivated to adapt its actual velocity to reach the velocity it prefers to walk, called the preferred velocity.…”
