摘要
为了顺应现阶段交通技术信息化发展趋势,确定高速公路数字化交付的数据定义基础,探讨了一种高速公路信息要素的分类方法。基于对相关标准和规范的理解,梳理项目设计和管理文件,确定高速公路要素数据字典的三级分类顺序,同时以行业标准JT/T 697.2交通信息基础数据元第2部分为基础,在广度上进行高速公路信息要素种类的扩充,并确定了要素编码方式以及其属性字段内容。研究结果旨在明确高速公路数字化交付的数据定义标准,为实施公路工程数字化提供基础支持。
To adapt to the rapid development of transportation informatization,and determine the data definition basis of expressway digital delivery,this paper discusses a classification method of expressway information elements.Based on the study and understanding of relevant standards and specifications,sort out the project design and management documents,determine the three-level classification order of expressway element data dictionary.Concurrently Based on the Industry standard“Basic data element of transportation information———Part 2:Basic data element of highway information”(JT/T 697.2)the types of expressway information elements are expanded,and the element coding method and its attribute field content are determined.The research results are intended to clarify the data definition standard of highway digital delivery and provide basic support for the implementation of highway engineering digitization.
