道路可分为城市道路和公路两大类。公路的分类方法有两种:行政分类和技术分级。行政分类可分为国道、省道、县道、乡道和专用道路。公路分级是根据交通部行业标准《公路工程技术标准》的规定,按使用任务、功能和适应的交通量分为高速公路、一级公路、二级公路、三级公路、四级公路五个等级。 公路行政分类与技术分级没有对应关系,国道并不等于其技术标准就一定高,县道和乡道的技术标准不一定就低;也不等于一条道路就是一个标准。
Roads can be divided into two major categories of urban roads and highways. There are two types of road classification: administrative classification and technical classification. Administrative classification can be divided into State Road, Provincial Road, County Road, Country Road and dedicated roads. Highway classification is based on the Ministry of Communications industry standard “Highway Engineering Technical Standards”, according to the use of tasks, functions and adapt to the traffic volume is divided into highway, a highway, two highways, three highways, four highway four levels . There is no corresponding relationship between road administrative classification and technology classification. State Road does not mean that its technical standards must be high. The technical standards of county and township roads are not necessarily low; nor does a road mean a standard.
