摘　　要：动态分段技术可以较好地表达交通特征一对多的关系,动态描述道路各种属性数据之间的关系,极大提高数据处理能力。通过对动态分段技术的研究,为交通基础设施查询系统建立了动态分段结构表,对动态分段技术进行了理论分析与算法描述,建立了系统的Geodata-base模型及高速公路主车道-匝道拓扑模型,建立了基于动态分段技术的交通基础设施查询系统。该系统实现了交通基础设施查询系统属性信息的动态显示和更新,提高了多重属性查询效率,在实际应用中取得了良好效果。Dynamic segmentation technology can express the one-to-many relationship of transportation characteristics,describe the relationship of a variety of road attribute data dynamically and improves data-processing capability greatly.Based on the research of dynamic segmentation technology,the table of dynamic segmentation structure was formed for transportation management,and the theoretical analysis and description of the algorithm were given,the systemic Geodatabase model and the topology model of the main lane and ramp of Jilin provincial expressway was established,and the transportation infrastructure query system based on dynamic segmentation was developed.The system makes the dynamic display and renewal of the attribute information of the transportation query system come true,improves multi-attribute query efficiency,and obtains a good result in practice.
