Hello,
I have been trying to place approximately 200 people at varying locations at
the start of the simulation and then I just want them to wait there until
another vehicle arrives to picck them up.
Once that vehicle gets close and stops then the initialization person/vehicle
can disappear and essentially take 1 of the capacity of the arriving vehicle
like a bus picking someone up. I have read all the Long, Lats into a data
frame, and converted it to X,Y cartesian with no issues. I then move using
moveToXY( ....., with keepRoute=2) as this is the only method that seems to not
get the 100-meter road nearby error.
I initially created a simple route as launching pad where I then moved to the
other more important initialization point read into the data frame, but what
happens is although vehicle WIP count on gui is correct they are not available
to the simulation, as they seem to be teleporting.
I then decided to load 194 random trips just to get them going into the model
moving, and then move them to the initialization point. I am using vehicles to
do this as it was the only object that had movetoXY function, but I do see
persons or pedestrians' object. I was wondering if someone could give some
guidance of how best to move appropriate objects to allocation waiting for
later bus to come pick them up. I am still working through trial and error and
will look back here to see if any code example exits to do this rudimentary
item at initialization.
