Evaluation of Topology Description Models in Road Network Formats

Topology is a particular feature of road networks. Topology refers to properties, such as the connection of roads, but not only through their axes or reference lines, but also at the level of lanes. The map topology of road networks does not currently have procedures that can be expressed in mathematical formulas (or only to a minimal extent), but can only be implemented by algorithms. Our research, therefore, aimed at observing such topological regularities and then developing a method of investigation, by constructing rules and additional algorithms. To test this work, we used synthetic and real data, focusing on the case of map content embodied in four formats. In this paper, we present the test methods for the data models, the results of our test runs and finally, we point out that topological checks are extensively justified to determine the quality of the produced map. In the future we plan to develop an automatic correction mechanism based on this.
