摘要
对集中式和分布式两种智能交通系统信息集成模式的分析,提出了一种面向需求的信息集成模式。这种模式下,需要对智能交通系统现有资源和信息集成需求进行分析,以便制定合理的智能交通信息集成策略。选择信息集成矩阵分析方法来制定智能交通系统信息集成策略,并结合实例给出了具体的实现步骤。这种方法充分考虑了系统与数据之间的映射关系,完全能够满足智能交通系统信息集成策略制定的要求。
According to the analysis of two modes of ITS information integration, a requirement-oriented ITS information integration mode was put forward. With this mode, the analysis of existent resources of ITS and requirements of information integration was needed to work out a proper strategy of ITS information integration. On the basis of comparing different requirement analysis methods, information integration matrix analysis was chosen as the method used for integration strategy of ITS. An example was presented to carry out this method. This method considers the mapping relations between system and data. Therefore, it perfectly satisfies the requirement of working out the information integration strategy of ITS.
