TRAFFIC DATA PLATFORM AS ITS INFRASTRUCTURE FOR INTELLIGENT TRAFFIC DATA MANAGEMENT

摘要

Many industrial and research projects in the field of ITS need traffic data for realizing new andinnovative applications. However, it is often costly and time-consuming to acquire or to accesssuch data. That is where a complete traffic data platform with standardized access can increasethe efficiency of research for current and future ITS projects. For this purpose, the Institute ofTransportation Systems of the German Aerospace Center (DLR) is developing a modular andSOA based Traffic Data Platform (TDP) which provides all basic tools for storage, processing,fusion and management of traffic data from various sources. In this context, the TDP isespecially designed to support “online” services and information in a most efficient way.Moreover, due to its modularity and extensibility, the platform itself can be used as aframework for testing and developing new methods and algorithms for data fusion and qualityestimation, for example. This paper gives a general overview about the TDP and focuses on thetechnical aspects. The main functionalities, non-functional requirements, and the key playersare mentioned as well as the supported data. Finally, a selected use case scenario shows thepractical applicability of the TDP.
