【摘要】 在智能交通系统(Intelligent Transportation System)(ITS)中,车辆导航系统占有极其重要的地位,数字道路地图(Dgital Road Map)是制约车辆导航系统发展的关键因素,数字地图的质量直接影响着车辆导航系统的功能。廉价、完整、无缝的数字道路地图是车辆导航系统发展和推广的关键。本文着重研究了数字道路地图的相关功能,车辆导航系统对数字道路地图的要求,全球数字道路地图的主要供应者及数字地图的主要格式和它们支持的导航功能,从中我们可以看出全球数字道路发展的现状及趋势。最后对我国数字道路地图的发展提出了建议。更多还原

【Abstract】 Vehicle navigation systems are very important in ITS. The Digital Road Map(DRM) is a key element which restrict the development of vehicle navigation systems, and also the quality of digital road map affect the functions of vehicle navigation systems directly. For the development and popularization of vehicle navigation systems, it is important that the digital road map is cheap integrity and seamless. The related function of digital road map, the request of vehicle navigation systems for digital road map, the main provider and formats of digital road map , are discussed in this paper. So we can espy the status and trends of digital road map, and at the end of this paper 1 bring forward some advice for the development of digital road map in China更多还原
