Research on Equalization of Public Transportation Services Based on Perspective of Groups – A Case Study of Beijing

In this paper, by quantifying the value of public transportation travel benefits of ordinary travel groups, economically disadvantaged groups, and physiologically disadvantaged groups, this paper establishes a public transportation travel benefit evaluation index system, uses a questionnaire survey method to collect index data within Beijing, and establishes a TOPSIS model. Based on the travel benefit values of the three groups, the benefit compensation for disadvantaged traffic groups is considered, benefit compensation factors are introduced, the degree of equalization is evaluated based on the Wilson entropy model, and the level of equalization among public transportation service groups in Beijing is empirically studied to find out an important indicator that restricts the level of equalization.
