[sumo-user] Output differences between TraCI & libsumo for mesosim

[marcelreppi <marcelreppi@xxxxxxxxx>]

Hello,

I have a custom TraCI scenario and for performance improvement I wanted to
test how much faster libsumo and mesosim are in my case.
I am only interested in the routes vehicles take and how much distance they
have driven.
I would expect that my output data is the same when using TraCI or libsumo
with/without mesosim.
I wanted to make sure that my output is not affected by some unexpected
behavior so I collected some data and realized that there are quite some
differences.

I have some polygons which I call zones and I track the vehicle movement in
these zones.
The driven distances are sometimes very different between the different
execution settings (TraCI/libsumo with/without mesosim).

I have attached a picture with my collected data.
I tested two scenarios:
    - "n" which is just regular SUMO with only periodic rerouting
    - "rr" which is TraCI with periodic rerouting AND custom rerouting

Is my expectation wrong? Am I missing something?

Any help is appreciated!

Thanks!

Best regards
Marcel
