An evolutionary game model captures dynamic interactions between operators and passengers under alternative allocation strategies. The framework is validated through a case study in Harbin, China. Results demonstrate that the optimal configuration reduces annualized system cost by approximately 17.8% (≈266 million CNY) relative to the baseline and identifies cost-effective combinations of key decision variables. Sensitivity analyses confirm robustness across varying wireless charging facility scenarios.

The main reason for this insignificance is the mutual offset between direct and indirect effects: on the one hand, they directly increase traffic congestion by 1.04%, but the direct effect is statistically insignificant; on the other hand, ride-hailing services indirectly mitigate traffic congestion by 1.18% through reducing private car ownership by 6.29%, indicating that private car ownership plays a suppression effect in this impact path.

This study proposes intuitive, field-implementable measurement methods for the parameters: a cumulative count curve with oblique plots to estimate saturation flow; and theory-based, sensor-independent procedures to estimate jam density and wave speed.
