Abstract:
Real time traffic monitoring is a fundamental requirement for improving the efficiency of transportation systems. The emerging technology of wireless sensor networks (WSNs) allows of distributed traffic monitoring systems at large scale with low cost of installation and maintenance. The develop of cheap sensor nodes with integrated computing and wireless communication capabilities has changed the scenery of real-time traffic data acquisition. This paper describes a WSN based on an array of acoustic sensor employing an effective signal processing and a novel parameter estimation procedure. Key features are traffic monitoring and localization of traffic congestion event performed in real time, with an impressive space scale. A particular case study is presented starting from a real problem and achieving the best architectural solution. Finally the results of theoretical analysis and extensive experimental results of a prototype installation on a motorway are provided.
