Application of Dynamic Grey Model in Pavement Performance Predication

摘要

In light of the situation that lack of history data about pavement performance and some matters with traditional prediction model, on the base of traditional GM (1, 1) model, a dynamic grey model was constructed by replacing original data with forecasting data. It solved the problems that lack of original data and data divergence of traditional GM (1, 1) model, and it was applied to prediction about pavement performance of an expressway in Shaanxi, by comparing with other prediction models, the dynamic grey model has obvious advantages.
