ITS applications are ommonly composed of many subsystems that must work together but operate independently. To maximize the benefit of such ITS applications, it is paramount that these subsystems work in harmony with one another. The need for information sharing and integration between various ITS subsystems is calling for the development of advanced data sharing and integration technologies. In this paper, we introduce a Common Information Platform (CIP) called Virtual Common Information Platform (VCIP), used as a universal framework for cost-effective and efticient sharing and exchanging of ITS data. The system architecture is unique in that it combines centralized control with distributed processing. It can support data conversion and integration across an array of heterogeneous ITS subsystems, and control the access level of each subsystem according to its access authorization. The operational methods and key technologies of VCIP along with an application example are described in the paper. A prototype system is presented to further illustrate the key features and functionality of the proposed VCIP.

在分析决策属性（指标）均衡性的基础上，提出用相对熵作为定量描述这种均衡性的指标，并由此给出了属性指标的均衡性评价映射模型。算例表明了该模型的有效性。

提出一种虚拟共用信息平台技术（VCIP）作为ITS子系统间信息共享和信息集成的基本框架，以高效率低成本地完成数据共享和数据交换。VCIP结合了集中控制和分布处理的优势，具有开放性，根据访问授权与数据类型控制服务水平，支持跨平台ITS异构数据的转换与集成。分析了VCIP对ITS集成的重要作用，提出了VCIP的体系结构、操作机制和实现技术，并通过一个基于VCIP的出行信息系统——VCIP2TIS原型系统验证了VCIP的特性和功能。
