Abstract
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.
