Track collection in Anylogic

Question

I'm building a pedestrian model using Anylogic. I have set my agents move in several groups between S2/S3/S4 and S1 (the movement direction is indicated by the blue two-way arrow in the figure). Background picture for problem statement

I have build a cyclic event and type these code in "action" to collect their track data:

t = time();    //get time
for(Agent p: level.getPeds()){
        x = p.getX();    //position x
        y = p.getY();    //Position y
        id = p.getId();    //get pedestrian id
        collectionTime.add(t);    //add data
        collectionID.add(id);
        collectionX.add(x);
        collectionY.add(y);
        Timeid.add(t,id);
        XY.add(x,y);
}

I also add these code in "Main-Agent type_Agent actions_On destroy" to write data into excel file:

TrackCollection.writeDataSet(Timeid,1,1,1);    //TrackCollection is the name of excel file
TrackCollection.writeDataSet(XY,1,1,3);

But in this way I can only collect all the trajectories together in the model. How can I collect the tracks of these different groups separately? Or how to collect tracks from different PedSources?

can you clarify the code, this is not actual correct syntax. Also, what are TrackCollections? — Benjamin, Aug 04 '22 at 12:18
Thanks so much, Benjamin, for comments. I have edited my question and clarify the code. The current question is complete. — GradyC, Aug 04 '22 at 16:16

Your question is a bit unclear, nevertheless, if you are creating groups, you can do this after creating a groupId variable in your pedestrian agent.

for(Pedestrian p : group.getPeds()){
    p.groupId=group.getId();
}

you can use this groupId and export it to your excel too so you can keep track of the groups
