Parvan 2, 300223 Timisoara, Romania, e-mail: radu.precup@aut.upt.ro Keywords: wireless sensor networks, traffic decongestion, aggregation, traffic control. Abstract In this paper we present a sensor networks architecture for urban traffic management, hierarchically structured on three layers: sensing, processing & aggregation and control. On the proposed architecture we define traffic decongestion methods for vehicles and also for pedestrians. Finally, we present a case study on how traffic control can be implemented in a concrete situation, based on the proposed architecture, pointing future directions of development. References [1] M.
