Dear all,

I would like to simulate a relatively large city network in SUMO (cca 140 km2, 
170 k inhabitants)  and use the simulation results as a function sample in an 
optimisation algorithm. As such I would like to get the results relatively 
fast, meaning that at least for the initial runs I would like to use the 
mesoscopic subsystem of SUMO.

Now, to make things more interesting, I need to simulate electric public 
transport vehicles (plugin buses and hybrid trolleybuses). As I understand it, 
the meso subsystem in SUMO does not support neither public transport, nor 
electric vehicle, nor TraCI (which I currently use to simulate the model of the 
trolleybus).

I have some resources to spend on this, and I am trying to estimate the effort 
to get the missing pieces in place: The plugin bus is in fact a larger EV with 
some additional parameters, so the existing EV model could be adopted for this 
and I will not need the TraCI; the hybrid trolleybus is in fact the same plus 
overhead wires (which are simulated as a sequence of charing stations at the 
moment); I assume that this boils down to porting the existing EV model + our 
extensions into the mesoscopic subsystem. The other thing is the implementing 
the correct handling of PT routes (and possibly PT priority) within the 
mesoscopic subsystem.

Can anyone comment on this? Does anyone actively use the mesoscopic subsystem 
currently? Are there any activities in this respect that we could participate 
on?

Thanks for information!

Jan
