Abstract:In order to provide an intuitive understanding of passengers' experience in urban rail transit, a perceptible and identifiable index system of passenger satisfaction evaluation was established from the perspective of passengers, and the Criteria Importance Through Intercriteria Correlation (CRITIC) method was adopted to achieve objective index weighting. The primary algorithms of cloud model theory were used to generate the evaluation cloud and the result cloud, which can more intuitively represent the evaluation results by the digital features of clouds and comparison of cloud figures. Finally, the passenger satisfaction evaluation of Shanghai Metro Line 2 was taken as an example to verify the validity and rationality of the evaluation approach, while the comprehensive evaluation result not only reflected the degree of passenger satisfaction, but also provided a measure of the difference in passenger perception and degree of consensus, making it more valuable to use.
