城市复杂道路网络T-GIS数据模型
T-GIS Data Model for Urban Complex Road Network
摘要
Abstract
According to the complex situation of modern urban transportation network, a new T-GIS data model for urban complex road network (UCRN) was established to describe its complex characteristics. First, the complex network theory was introduced to validate the complexity of road network. Then on the basis of three aspects such as the comprehensive description of UCRN, the attribute expression, and the internal logical relationship of UCRN, TGIS data model was constructed. Finally, T-GIS data model proved to be effective in applications, and clearly represented spatial information and internal logic relations of UCRN. The study provides desired data for road congestion and traffic flow analysis, route induction and road network evolution.关键词
