Rationality Evaluation of Urban Road Network Plan Based on the EW-TOPSIS Method

This paper was carried out with the objective of evaluating the rationality of an urban road network plan. The research was kickstarted by analyzing the urban road network in question, from which a corresponding rationality evaluation metric for the urban road network plan was formulated after taking into account the scale of the road network structure, the scale of the public transportation route network, and the traffic-regulating functionality of the road network. Using the metric in combination with the EW-TOPSIS (entropy weight and Technique of Order Preference Similarity to the Ideal Solution) method, a comprehensive road network plan rationality evaluation model was established. Finally, the effectiveness of the model was verified by evaluating the rationalities of the urban road networks in Beijing, Shanghai, and six other cities in China using the EW-TOPSIS method, and conducting a sensitivity analysis on the produced rationality evaluation indices.
