This feature class was created for the following uses: a.) Geocoding using street centerline distance interpolation, b.) identification of ownership and jurisdiction of roads within the county, c.) maintenance, mapping, and analysis of speed zones, d.) maintenance, mapping, and analysis of federal functional classes (FCC), and e.) general cartographic uses. The road lines are generally within a few feet of the road centerlines as seen on aerial photos.本要素类（feature class）专为以下场景创建：a.) 采用道路中心线距离插值法开展地理编码；b.) 识别本县范围内道路的所有权与管辖权属；c.) 速度管控区的维护、制图与分析；d.) 联邦功能等级（Federal Functional Classes，FCC）的维护、制图与分析；e.) 通用制图应用。该道路线与航空影像中可见的道路中心线之间的偏差通常仅为数英尺。
