摘要
从计算机学科的视角分析了智能运输系统(ITS)的特征,抽象出了ITS信息平台需要研究的两个重要问题:上下文感知计算与异步、分布式的系统管理与协同。用上下文计算为ITS中各个实体的行为提供依据,实现智能运输。通过异步、分布式的系统管理与协同,协调ITS中各个实体间的交互,从而达到整个ITS的协调运行。对ITS信息平台的这种抽象符合ITS的客观实际,适合用先进的计算机技术对ITS进行研究和开发。
This paper analyzes the ITS＇ features and essentials from the view of computer science, abstracts two important research points of ITS information platform： one is context aware computing, the other is asynchronous and distributed system management. The context aware computing provides information and knowledge for each entity to decide what to do, and let the whole ITS to achieve intelligent transporting. The abstraction of ITS information platform has two features： the one is this kind of abstraction reflects the objectivity of ITS, the other is this kind of abstraction is suitable for research and development from the view of computer science. 6 refs.
