Traffic flow estimation of the Sioux Falls scenario. a The Sioux Falls network where the initial traffic flow defines the edge width. The half-arrows indicate the direction of flow. Relative errors between the NiN model and the results of the traffic flow simulations are colour-coded. Overestimations of the traffic flows are coloured red, underestimations blue. b Boxplot and violin plot of the relative errors for the flows and costs of the Sioux Falls scenario
