Method for predicting expressway and urbanization development coordination level

The invention discloses a method for predicting the expressway and urbanization development coordination level. The method comprises steps that an expressway system development level model and an urbanization system development level model are respectively established; an expressway and urbanization development coordination level prediction model is established; expressway and urbanization level coupling coordination level evaluation standard systems are established; the BP neural network is designed, the BP neural network is employed to carry out error analysis on CCI index prediction values,and the relationship between expressways and urbanization development in future years is further predicted. The method is advantaged in that technical supports are provided for the planning and layout of the expressways and urbanization development decisions, and the inter-coordination capacity of the expressway systems and the service capacity of the expressways are guaranteed to adapt to the urbanization level at a spe
