智能交通系统(ITS)是一种信息化、智能化、社会化的新型现代交通系统。云计算将大量用网络连接的计算资源统一管理和调度,构成一个计算资源池向用户按需服务。本文通过研究云计算技术在智能交通领域的应用,提出基于云计算的ITS平台,解决了共享处理海量交通信息的难题。 Intelligent Transportation System (ITS) is a new type of modern transportation system of information, intelligence and socialization. Cloud computing will be a large number of network computing resources unified management and scheduling, constitute a computing resource pool to users on-demand service. This paper studies the application of cloud computing technology in the field of intelligent transportation, puts forward ITS platform based on cloud computing, and solves the problem of sharing and handling massive traffic information.
