Dear all,
I am trying to calibrate a SUMO scenario that uses mesoscopic simulation
(—mesosim). I came across the following in the
Documentation<https://sumo.dlr.de/docs/Simulation/Meso.html#outputs> for the
mesoscopic simulation:
* No lane specific output is possible.
*
<laneData>-output<https://sumo.dlr.de/docs/Simulation/Output/Lane-_or_Edge-based_Traffic_Measures.html#lane-based_network_states>
will be treated like <edgeData>-output.
* netstate-dump<https://sumo.dlr.de/docs/Simulation/Output/RawDump.html>
will report vehicles as child elements of <edge> instead of <lane>.
I have two questions related to this?
First, why is it that the lane-based outputs are not possible here? Is it
because that the lane-level simulation resolution is lost in the mesoscopic
simulation?
Second, are outputs from the E1detectors (loop detectors) for a mesoscopic
simulation are also edge-based. Because I observed that all the lanes of a
specific edge have equal outputs (see output snippet below), this seems likely,
but I think it is better to confirm.
<interval begin="18000.00" end="18900.00" id="e1Detector_108626246_0"

Apologies, if a similar question has been asked before, could you please link
me to that thread.
Thanks for your time.
Best Regards
