| Re: [sumo-user] Status of mesoscopic simulator |
Hi Jan, we are actively using the mesoscopic simulator all the time, here are some answers: 1. As long as you don't need to model the pedestrians boarding and driving, public transport is not different from regular vehicles and should be handled by the mesoscopic model (meso for short) just as well. There are some issues with stops where meso currently only evaluates "duration" but not "until" but this is probably fixed easily. 2. The existing EV model has essentially two parts: the battery model and the charging stations. The energy consumption can already be modeled in meso as well but you would probably need to adapt the charging stations and their interaction with the battery. 3. There are small works on improving meso and there are works on the battery / charging model as well but currently I know of no effort to bring the two together, although I consider this a good idea. If you wish we can try to have a phone call to discuss about how to approach this.

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?
