Re: [sumo-user] Output (files) values from TraCI

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello Lara,

It wouldn't be too difficult to retrieve data from the tripinfo- and vehroute-device by extending the vehicle.getParameter API (https://sumo.dlr.de/docs/TraCI/Vehicle_Value_Retrieval.html#supported_device_parameters)

However, your requirement to get these values when the vehicle exits the simulation is hard to achieve because this also triggers cleanup of the devices.

I think the easiest way to get these values at runtime is supply a socket address instead of an output file for each of these output options and then have your script read from these sockets. (https://sumo.dlr.de/docs/Basics/Using_the_Command_Line_Applications.html#writing_files)

regards,

Jakob

Dear All,

I need to retrieve the same info that can be dumped in the following files:
* https://sumo.dlr.de/docs/Simulation/Output/TripInfo.html
* https://sumo.dlr.de/docs/Simulation/Output/VehRoutes.html
* https://sumo.dlr.de/docs/Simulation/Output/StopOutput.html

but I need it to be done during the simulation when the vehicle/person
exits the simulation.
Is there a way to do it using TraCI without having to subscribe to all
the vehicles+people and compute them all by myself? This solution
would not scale, and I need like to keep consistency with sumo for all
the retrievable stats. For example, the timeLoss must be the same in
the sumo output and in my results.

Any Ideas? I cannot find any API that would help me in doing this, but
I'm willing to try to implement new ones if it's feasible.

All the Best,
Lara
