| 摘 要： | 由于互通式立交桥错综复杂的拓扑结构特点,使互通式立交桥更新时存在拓扑联通性维护困难的问题,针对该问题提出一种顾及拓扑联通性的互通式立交桥增量更新方法.该方法以21种互通式立交桥类型为基础,通过分析每种类型的拓扑结构特点,用计算匝道数和平面交点数组成的二元组值来识别这21种互通式立交桥;根据不同类型互通式立交桥需要维护的...

| Abstract: | Due to the complex topological structure of the interchange overpass,it is difficult to maintain the topology connectivity using the current updating methods.Therefore,this paper proposes an incremental updating method for the interchanges considering the topological connectivity.The method is based on 21 topological structure types and nine change types of interchanges.The topological structure types are identified by the number of ramps and the topological intersection points.Based on the 21 categories of topological structure and the nine change types of the interchanges,66 rules for the incremental update of interchanges are designed.Finally,an incremental updating prototype system is developed,and the incremental updating method for interchange overpass is implemented for 1∶10000 road network data.The methods are verified by Changsha OSM road network data. |
