摘要
首先,通过交通信息路段编码建立实时交通流信息与逻辑路网的关联;然后,提出了根据多路段的上下层对应关系实现实时交通流信息与静态分层路网的融合表达。实验结果表明,此方法可以实现动态交通信息在导航电子地图中的多尺度可视化,满足动态导航的需求。
Based on analyzing the characteristics of real-time traffic information （RTTI） and navigation data model, we point out the difficulties to express RTTI in hierarchical road network. We focus on the fusion method for RTTI and hierarchical road network. Firstly, the relationship between RTTI and logical road network is established by RTIC. Then, we propose the fusion method based on the relationship of multi-link in the upper and lower layer. Lastly, the results demonstrate that the method achieves multi-scale representation of real traffic map in mobile terminal and meet the requirement of dynamic navigation.
