Abstract:
Recent advancements in information and communication technology accelerate the development and deployment of intelligent transportation systems. Cooperative traffic systems utilize information collected by road users and traffic operators about their immediate environment sharing it system-wide, enabling services for all traffic entities. In this work, we contribute a data processing and data fusion middleware relying on wireless mobile sensor nodes and public infrastructure services for traffic data collection for future cooperative traffic applications and services. The system is demonstrated with an example application, utilizing mobile phones with integrated sensors as sensor nodes and producing the visualization of travelled routes annotated with travel mode and detected anomalies of road surface. Middleware features include modular component-based architecture, reconfigurable and reusable data processing components, dynamic addition of components and interfaces into the system in runtime and data fusion of heterogeneous sensor data through chaining of components into application specific data fusion levels.
