为了最大限度的降低高速公路的养护成本,目前结合边际成本管理的原理,通过对道路长度、交通流量和养护成本之间的分析,建立高速公路多元回归分析的数学模型,主要是对专项工程和预防工程的养护方式通过统计的方法推导出边际成本表达式,从而提出了高速公路养护成本的预测模型,然后分析了高速公路养护费用各项指标,得出对高速公路养护费用起决定性作用的是高速公路的长度和流量。
In order to reduce the maintenance cost of expressway to the maximum extent, combining the principle of marginal cost management, the mathematical model of multiple regression analysis of expressway is established through the analysis of road length, traffic flow and maintenance cost, mainly on the special engineering and The maintenance method of prevention engineering deduces the marginal cost expression through the statistical method, then puts forward the forecast model of the highway maintenance cost, and then analyzes various indicators of the highway maintenance cost, obtains the decisive function to the expressway maintenance cost Freeway length and flow.
