Evaluate the Utility of High-Speed Railway Opening by Forecasting the Induced Traffic with Satisfaction Investigation in China

The induced traffic is newly proposed and together with the economic growth as a new indicator to measure the effectiveness of the high-speed railway opening in a more intuitive way in this study. The Matrix Completion and Canonical Correlation Analysis are used to realize the measurement and prediction of this index on the basis of the satisfaction investigation on the 27 high-speed railways in china. It is demonstrated that instead of only calculating the economic benefits brought by the construction of high-speed railway, this indicator can find the most urgent railway to be improved by directly evaluate the existing railway facilities from the perspective of passenger satisfaction investigation.
