Evaluation of Inter-City Railway's Function Orientation in the Comprehensive Transportation Corridor

The inter-city railway is concentrating on the development and the construction of comprehensive transportation corridor. Scientific and reasonable evaluation is of great significance to guide the inter-city railway's function orientation. The inter-city railway function not only need to meet inter-city passenger traffic demand, but also should be more apparent in technology-economic characteristic advantages and substitution compared to other inter-city transportation mode. So this paper established six quantitative evaluation indexes which are speediness, convenience, comfortableness, economy, punctuality and security, introduced the evaluation model of grey correlation. At last this paper took Beijing-Tianjin inter-city railway as example to prove the practice, feasibility and correctness of the evaluation mode.
