HS-SFM parameters.

The Pedestrian’s parameters
𝑚 = [77, 83] kg	The pedestrians’ mass: uniformly distributed within the range [77, 83] kg
𝑟 = [0.25, 0.30] m	The pedestrians' radius: uniformly distributed within the range [0.25, 0.30] m
The SFM’s parameters
𝑘=1.2×10^5 kg/sec^2	The strength of the contact (pushing) force
𝑘=2.4×10^5 kgm^−1 s^−1	The strength of the friction
𝑣^0=1.34 m/s	The preferred velocity
𝜏=0.5 s	The reaction time
𝜀𝜖0,0.05∗𝑣^0/𝜏	The fluctuation source of the pedestrian’s acceleration is randomly assigned to each individual
The HS-SFM parameters
HMCR = 0.95	Harmony memory consideration rate
HM = 20	Harmony memory size
PAR = 0.75	Pitch adjustment rate
NI = 500	Number of improvisation
