Wireless Sensor Networks to Improve Road Monitoring
Mario Collotta, Giovanni Pau, Valerio Mario Salerno, G. Scat · InTech eBooks · 2012
In this chapter an approach to improve road monitoring through wireless sensor networks is described: several sensors may be distributed along a road in order to detect traffic flows, speed, and the continued occupation of the road. Each WSN cluster offers a monitoring system based on videotapes and, at the same time, produces information which can be processed to provide a clear interpretation of the road situation regardless of weather conditions [1, 2]. Therefore, it is necessary to integrate video monitoring information with parameters measured by other sensors, e.g. magnetometer or power sensors, for traffic detection [3–5]. Advantages about WSN usage in this area are several. Some of them have been already shown in literature. Others derive by the proposed approach.
