| 摘 要： | 为了有效地描述实际道路网络，提高汽车导航系统的运行效率，建立了一种新的电子地图的路网模型。在分析了嵌入式系统特点的基础上，对路网的数据结构进行了简化。采用重整实体ID的方法，进一步提高了数据的处理效率。实践证明，该模型可以较好地表述实际的道路网络，结构精练，处理效率高，适合车载导航系统，特别是嵌入式车载导航系统的要求。

| Abstract: | To effectively describe the real road network and improve the efficiency of vehicle navigation system,a road network model in digital map is created.The data structure of road network is simplified based on the analysis on the features of the embedded system.And by rebuilding object's ID,the efficiency of data processing is improved.The results show that the model can better describe the real road network,with a simple data structure and high efficiency in data processing,so is suitable for on board navigation system,especially the embedded system. |
