Sensor Network Architecture for Cooperative Traffic Applications

The advancement of information and communication technologies accelerates the development and deployment of intelligent transportation systems. In the future cooperative traffic system, actors collect information about their immediate environment sharing it with each other, enabling all traffic entities to become context-aware. In this work, we contribute a practical data collection and processing system using mobile phones as sensor nodes. The system is demonstrated with two example applications, producing the visualizations of the travelled route annotated with the travel mode and the detected anomalies of the road surface. Modular component-based architecture enables the reuse of the system in future applications and the developed reconfigurable components facilitate dynamic additions of data processing algorithms into the system in runtime.
