To evaluate and analyze the spatial dimension feature of transportation network, Travel Time Ratio Inequality Index is proposed in this paper. The proposed index utilizes the Lorenz Curve to evaluate the traffic load variations among road regions of transportation network, and the inputs of Lorenz Curve is redefined to match the needs of spatial analysis. Based on Internet traffic data, the mathematical model of Travel Time Ratio Inequality Index is deducted, following with the solution method. The numerical results from comparing the index performance of ten large-scale cities justify the validness and usefulness of the proposed index and the related mathematical model.
