Road Network Pyramid Model

Abstract:

It is a challenge in the research field of GIS-T and ITS to design a road network model that can well express the full range of transportation information. The existing Multi-hierarchy road network models often have some defaults, such as repeated storage of data, high degree of redundancy, difficult to analyze network, etc. Based on the analysis of image pyramid model and road feature hierarchy, a road network pyramid model has been proposed in this paper. This model has the adaptive ability to express multi-scale information and can descript road network the most detailedly with comprehensive road characteristic of all hierarchies. Low degree of redundancy of spatial and topologic data is another advance of the model. So this model is more suitable for multi-hierarchy analysis of road network.
