Hello SUMO is quite far away from the Nagel-Schreckenberg model (roads and movements are continous) so you will have create a special road network and write a new vehicle model. If you have the latest development version (it won't work with 1.3.1), the call below will split a network in cells of 7m length: netconvert -s net.net.xml --geometry.max-segment-length 7 --geometry.split -o net2.net.xml [1] The model isn't part of SUMO. I'm not aware that anyone tried to do this in SUMO so it would be quite experimental. [2] see https://sumo.dlr.de/docs/Developer/How_To/Car-Following_Model.html [3] Yes that should be possible. The key thing would be to round vehicle speed to a multiple of the cell length
