Re: [sumo-user] On ramp simulation
Hi Michael,

Thank you, I experimented with lcPushy and could not find an apparent difference in behavior between 0 and 1 setting and for both models SL2015 and LC2013

Best

Hi,
I think SUMO's default model is less aggressive when changing lanes than the one used in the other example. Try changing the pushy parameter, see http://sumo.dlr.de/wiki/Simulation/Safety#Lane-Changing_Model

Best regards,
Michael

Hi
I am trying to simulate a simple freeway on-ramp scenario, in which traffic
from on-ramp causing jam on all freeway lanes, as you can see in
http://www.traffic-simulation.de/onramp.html when increasing onramp flow.
What I am getting in SUMO is traffic slow down only on the the lanes
closest to the on ramp and the other lanes continue to flow, I was
expecting traffic from first lane to improve their situation and try to
change to other lanes which in effect jam the other lanes

Am i doing somthing wrong ?
