Thank you, Mr.Jakob
About (ii), yes, my main goal is to get temporary formation of pedestrian
groups. Realistic looking visualization is also important but not the main
objective.

(iii) if it's impossible to take the length of a platoon into account, I
would change a bit in my environment, for example, the platoon has a very
small distance between each AGV, then no one could come between two AGVs.
Therefore the platoon of several AGVs would become a unique AGV which is
long, containing several carriages (each carriage is a single AGV). This
long AGV lets pedestrians notice it and the length prolongs waiting time
for them. Therefore, due to waiting so long, the gap acceptance of
pedestrians will reduce in the near future.
