For a straight road segment without intersections the main determinant for flow is the insertion capacity. See https://sumo.dlr.de/docs/Simulation/RoadCapacity.html However, In an urban setting it's likely that the real-world capacity is impacted by intersections so the simulated capacity for a straight road segment will overestimate real-world capacity. If you are mainly interested in the capacity and you do have counting data, you could simply use the maximum recorded flow and be done with it.
