Traffic Data Platform based on the Service Oriented Architecture (SOA)

Kurzfassung

The DLR Traffic Data Platform (TDP) that is currently being developed by the German Aerospace Center (DLR) is an autonomous decentralised ITS system for distributed intelligent traffic data management and dissemination. Of course, there are many possibilities to design the architecture of such a traffic data platform where service oriented architecture (SOA) has been chosen for the current design of the TDP. In this paper the SOA design aspect of the TDP will be analysed and presented. The TDP as service provider is able to store, manage, aggregate, process and fuse traffic data from different sources like floating car data (FCD), loop detector data, remote sensing, video sensors and traffic relevant radar data into common traffic states and supply them as services to the TDP clients or service consumers who need these data to realize telematic services. The TDP is designed to support not only “online” traffic information but also services like multimodal routing for example. Having all these data in a single platform and making it available by providing standardised ubiquitous access, research and the development of new methods as well as the enhancement of existing methods such as data fusion, traffic state estimation, quality evaluations and innovative telematic services could be facilitated. Thus, the TDP contributes to more effective research in the field of traffic management.
