The Interport of Turin, as part of projects for a sustainable logistics, has activated a collaboration with Polytechnic of Turin for the experimentation of wireless sensors for traffic detection WIM and WSN, two systems presented in recent days at the ITS world congress (International Telecommunication Society) in Vienna.
The adoption of WIM systems allows the acquisition of information on the type of vehicles which, integrated with those relating to flows, are essential not only for a more complete detection and analysis of traffic and the various outflow modes, but also functional to the development of new strategies for a correct one road infrastructure management: maintenance, safety in circulation, reduction of pollutants.
Improve the urban distribution of goods it is one of the indispensable conditions for making the future development of cities sustainable. An objective that cannot however be separated from a thorough, serious and precise analysis of vehicular flows that daily affect urban areas.
"Interport Company of Turin S.p.a. - declared the president Daniela Ruffino - has decided to experiment with these technologies in the logistics platform area. We are confident that they will provide us with useful information to optimize distribution processes and promote sustainable logistics. We also imagine that their use could be useful to the administrations of large metropolitan areas for some time looking for solutions capable of responding to traffic problems ”.
The network of WIM and WSN sensors, installed within the road pavement of the logistics platform, was deployed to cover four macro-areas into which the Interport territory was divided, each equipped with access points equipped with a GPRS modem for the transmission of the collected data, 6 repeaters and 32 magnetometric sensors (for a total of 16 detection lanes).
This technology has several advantages: sensors and repeaters do not require an electrical connection; access points are set up with a single wiring for configuration and power supply; in the event of maintenance or road surface remaking, the sensor can be removed easily without damaging it.
To complement the traffic study process through WIM and WSN sensors, a simulation model has been prepared that allows further evaluations regarding the data collected, for example related to the estimation of consumption and Polluting emissions produced, which certainly provide a valuable aid in the management or in the eventual strengthening and improvement of road infrastructure.
