云计算借助高速网络将各种计算能力联接起来，为交通信息提供了几乎无上限的可伸缩的计算能力. 本文分析了交通信息云计算的优势、特征、方法和部署，认为交通信息云计算也是一种信息高效采集和服务的概念，是实现交通行为控制的基础. 以车辆GPS定位信息的获取、传送、计算和应用为例，对比了浮动车信息现有处理模式与云计算信息处理模式，提出了以云计算模式产生高效用度、闭环可验证的个性化路径导航信息作用于海量驾驶员个体，实现控制性路径诱导的方法.

Research on Traffic Information Cloud Computing and Its Application

Cloud computing can provide traffic information almost unlimited and scalable computing ability with high-speed network to link up all kinds of computing power. Traffic information cloud computing is considered as a new concept for efficient information acquisition and service based on the analysis of the advantages, features, methods and deployment of traffic information cloud computing and it is essential for traffic behavior control. Taking the acquisition, transmission, calculation and application of vehicle GPS information, the existing floating car information processing method is compared with that of cloud computing. A method for cybernetic route guidance is proposed by cloud computing providing drivers high utility and closed-loop verifiable personalized route guidance information.
