Re: [sumo-devel] [sumo-user] Question: Extending SUMO using different model

Hi Omair,
first of all, I think this is rather a topic for the developer list, please 
let's continue the discussion there.

Of course it is, this is an open source project you can replace everything
you want ;-).
In fact, we added some models quite recently, see
src/microsim/cfmodels/. Not all of them are in a "working" state
but an implementation according to this interface allows
to modify the behavior of the vehicle in terms of the desired speed
and distance to the predecessor in all situations.

Not with the approach above. Well I suppose you could fake 
something by allowing only discrete speeds but in essence you 
would need to modify the net and the vehicle implementation
as well, which we already tried in one case but which is much
harder to do. Nevertheless we are always interested in the
implementation of new models, thus if you are willing to try,
maybe we can give hints.
