ITIS: Intelligent Traffic Information Service in ShanghaiGrid

Intelligent traffic information service (ITIS) is a typically grid application in ShanghaiGrid to achieve effective traffic management. Several issues and challenges needed to be explored in ITIS, such as resource sharing, middleware communication, traffic control grid, and so on. We implemented a prototype system of ITIS and carried out a field testing in Shanghai city. We show that by utilizing the grid technology, the expected performance can be obtained, such as stability, scalability, etc. Meantime, traffic status estimation and traffic surveillance can be well handled in ITIS.
