随着经济的不断发展,我国高速公路里程数不断增加,极大的方便了人们的出行。为确保高速公路正常运营,国家职能部门在高速公路养护上投入大量资金,如何在保证高速公路正常运行的基础上,降低养护成本一直是业内关注的热点。本文基于边际成本管理理论,构建高速公路养护成本预测模型,为养护工作的开展提供依据。 With the constant development of the economy, the number of expressways in our country keeps increasing, which greatly facilitates people’s travel. In order to ensure the normal operation of the expressway, the state departments invested a lot of money in the maintenance of the expressway. How to reduce the maintenance cost on the basis of ensuring the normal operation of the expressway has always been a hot issue in the industry. Based on the theory of marginal cost management, this paper constructs the prediction model of expressway maintenance cost and provides the basis for the maintenance work.
