(i) you can define different types of pedestrians (i.e. name S,N,D, etc)
and assign different maximum speeds
(ii) complex group behavior as described is quite far from the current
models. What is the main goal here?
- accurate travel times for persons (might work by making some persons
slower)
- accurate travel times for AGV (might work by making some persons
"bigger")
- temporary formation of pedestrian groups that block a bigger part of
the floor space (assemble, cross, disperse)?
- realistic looking visualization?
My guess is that the latter two points would be quite involved to model and
implement.
(iii) gap acceptance in sumo currently has no way to take platoons length
into account. The pedestrian behavior is using similar methods as that used
by cars coming from a minor road and this only looks at the closest
oncoming car. SUMO does allow some hooks to purposefully ignore conflicts
and you might use this to tune the gap acceptance (

)
