It is also mentioned that the left lane will be served faster than the right lane and hence minimizing travel time would be a better predictor. Akcelik's use of dominant and subdominant pathways. So it's a problem from a different angle. Both Fisk and Akcelik recommend using a different critical deviation and uptime for each channel. In Akcelik's model, the lane utilization rate is determined by the degree of lane saturation. The capacity of the channel group is then calculated and the throughput of each channel is
