IIP: An Event-Based Platform for ITS Applications

In this paper, we propose an event-based platform in support of developing Intelligent Transportation System (ITS) applications, especially applications compatible with the IntelliDrive(SM) environment. Essentially, it combines two components, i.e. the IIP Cloud Component and the IIP Client Component. The IIP Cloud Component provides canonical publish/subscribe (pub/sub) functions to both traffic management facilities and mobile nodes. The IIP Client Component provides mobile nodes with pub/sub functions which allow them to communicate with the IIP Cloud Component as well as with each other. We show that by leveraging heterogeneous data sources and various communication mechanisms in the ITS environment, IIP supports a wide variety of ITS applications.
