Re: [sumo-user] Class for person in Omnet++

Thank you.
I suppose "traci" is an attribute of DemoBaseApplLayer class. In this class "traci" is an instance of TraCICommandInterface.
However the TraCICommandInterface class has no attribute named "person"
How could I access it?

The default way to write position information is with --fcd-output.
If you need the information at runtime, you can call traci.person.getPosition(personID) 
The list of all person ids can be obtained with traci.person.getIDList() (This includes all persons generated by a personFlow)

I found a quick hack to get coordinates of all pedestrians in personFlow.
In the source code of SUMO, edit the file: GUIEdge.cpp. More specifically, find the statement:
and then write a new line: std::cout<<person->getPosition()<<std::endl;
It works, the position will be printed as sumo-gui runs alone.
However, a new problem arises: My project needs positions to be available while the simulation is running. But the data of position is not printed as choosing "Run as Omnet++ simulation". The simulation should end and a user should close the Qtenv, the data would be available in the terminal. I tried other ways (such as writing a file) but it doesn't change: data only is printed after a user closes Qtenv.
