摘要: 高性能选路解决方案对智能交通系统(ITS)效率至关重要,基于LarKC(语义万维网开源项目)提出了一种ITS设计方案,使得ITS可以利用移动互联网提供的海量、实时、群智的信息,而这种新的设计思路对选路算法提出了新的要求。对实际交通场景属性进行抽象,并通过实验表明该系统具有良好的选路性能,为智能交通的实现提供了新的思路。

Abstract: A high-performance solution to Intelligent Transportation System(ITS) is of vital importance. It proposes a new type of ITS which is based on LarKC. As a result, this new ITS can provide large amounts of information which is real-time and belongs to large-scale intelligent devices. At the same time, it needs a new and practical routing algorithm to apply to the new system. It abstracts attributes which exist in real-time transportation scene. Through experiments, it finds that the created system has high performance in routing, which provides a new idea in realizing ITS.
