Research of Pavement Performance Evaluation and Prediction System of Highway Based on Linear Regression Method

摘要

Highway evaluation and prediction system of highway pavement is used for evaluating and predicting utilization performance on the structure of the highway pavement by adopting computer technology. Performance evaluation and prevention system of highway pavement based on linear regression method is put forward in the article. Firstly, it is to analyze the detection data on actual road and establish an evaluation index model to influence the utilization performance of the pavement to work out each performance evaluation index. Secondly, it is to establish a performance index prediction model according to the performance evaluation index and adopt the liner regression method to fit model parameters so as to obtain the optimum fitting parameters. Finally, it is to finish performance prediction in accordance with the optimum fitting parameters and draw the performance index prediction curve. The test result shows that the method can effectively predict pavement performance.
