SOA-based model for the IT integration into the intelligent transportation systems

Abstract

Currently, the Intelligent Transportation Systems (ITS) are made up of a large number of technologies that are tightly-coupled. This has led to produce many ad-hoc systems that are highly dependent and its interoperability is extremely low. The service oriented architecture (SOA) paradigm allows the construction of loose-coupled distributed systems which can help to integrate heterogeneous systems that takes part in the ITS. In this paper, we focus on developing a SOA-based model for the Information Technologies (IT) integration into the ITS. In order to develop our model, the involved ITS technologies and services were identified and catalogued. In doing so, we applied our SOA model in order to integrate and decouple all the ITS technologies and services. By developing our model we identify that the Roadside Unit (RSU) and navigation systems are key elements to provide integration interoperability, compatibility, and expandability between ITS technologies and services. We have applied our model involving these elements in order to generate value-added ITS. A case study has been designed and implemented to illustrate the application of the model to a significant ITS service (parking management system) that includes all the components of our model.
