摘要
随着GPS/GIS/GSM车辆导航和监控系统的成熟和普及,导航系统电子地图中的道路数据模型的重要性日益突出。在非导航应用中较少研究的道路交通线模型,在此成了无法回避的且必须理清的问题。本文详细分析了现代城市路口的通行规则,论述了单线模型的缺陷,设计了适用于导航的双线多结点道路模型。
With the maturity and popularity of GPS/GIS/GSM vehicle navigation and monitoring system, the importance of road digital model in navigation system electronic map becomes prominent gradually. The model of road traffic line is seldom studied in non navigation application, that can't be avoided and must be dealt with clearly now .The article analyzes the traffic rule of modern city road exhaustively, it discusses the defect of single-line model and designs double-line, multi-node road model which applies to navigation.
