Data Modeling Method Based on CAD Intersection and Its Application

Xu Zhang, Min Huang, Jiajie Pan, and Jian Zheng
Abstract—Intersection is an important part of road network. In order to enrich the modeling methods of intersection, a data model of intersection is constructed, which contains Link, Node, Arc, Lane, and LaneConnector. With a planar CAD intersection map as input, geometric features and positional relationship between elements in the map are analyzed. Then the property data of the elements of the model, especially the logical topology data, are extracted, and a database of intersection model is constructed. Finally, a cross-shaped intersection is taken as an example to verify CAD intersection map’s feasibility for constructing intersection model.

Index Terms—CAD, data model, intersection, logical topology.
