2. Istimes CONSORTIUM Nine partners from Italy, France, Switzerland, Norway, Israel, Sweden, Romany, with the coordination of TERN Consortium (Italy) Project Manager Prof. Vincenzo Cuomo Technical/Scientific Coordinator Dr. Francesco Soldovieri Total cost 4.3 Meuro

3. ISTIMES MONITORING SYSTEM features Multi-sensing Multiscalar Non invasivity Systematic approach based on the integration of non invasive remote sensing and in situ technologies organized in a network and supervised by ICT architecture able to provide the stakeholders with friendly and updated information for a situation awareness about the status of the infrastructure

4. ISTIMES functions: Safety & Security Long-term monitoring for a correct management and planning of the maintenance and retrofitting interventions. Quick damage assessment, after crisis events for the fast evaluation of the status and the identification of anomalies in the dynamical behavior of the structure.

5. Istimes Technological pillars Design, assessment and promotion of an ICT-based system, exploiting distributed and local sensors, for non-destructive electromagnetic monitoring of the critical transport infrastructures. The system allows a high situation awareness in order to provide real time and detailed information and images of the infrastructure status. Integrated System for Transport Infrastructures surveillance and Monitoring by Electromagnetic Sensing

6. ICT SYSTEM ARCHITECTURE The ISTIMES infrastructure is composed of the following main components: Web-based interface components for the corresponding kinds of the electromagnetic sensors exploited in the project; an e-Infrastructure for geospatial data sharing; a Decision Support component which helps decision makers providing inferences and situation indexes; a Presentation component which implements system-users interaction services and information publication and rendering Network of state of art sensors scalable for the remote and in situ observations

7. ELECTROMAGNETIC SENSING TECHNOLOGIES Development and exploitation of: Synthetic Aperture Radar satellite based platform, Hyperspectral spectroscopy, Distributed Optic Fiber sensors, Electrical Resistivity Tomography, Ground Penetrating Radar systems, Infrared Thermography, Ground based systems for displacement monitoring. The integration of different sensing techniques allows to ensure spatial- temporal monitoring of the structure at different scales, sampling periods, resolutions and depths of investigation. SAR technique will allow a “global monitoring” meant as the monitoring not only of the overall infrastructure itself but also of the surrounding environment. The above monitoring is complementary to the “local monitoring” (i.e., the monitoring of the infrastructure itself) offered by the in- situ sensing techniques considered in the proposal.

16. conclusions  ISTIMES system is able to face the necessities of both long term monitoring and quick damage assessment of the infrastructures.  ISTIMES exploits an ICT system architecture, which is scalable and modular so to permit in an easy way the addition of new sensors and the modification of the sensors network.  ICT system architecture exploits Web technologies to supervise sensors and provide services and information through a Decision Support System and a Presentation Layer.  ISTIMES is based on the integration/synergy of electromagnetic sensing technologies organized under “different protocols”, able to face different hazards and crisis scenarios by complying with the necessities of low cost and fastness of the survey.  ISTIMES approach has led to the development of prototypical instrumentation and has been successfully validated by a large arena of activities at test sites and test beds.  ISTIMES has raised a strong interest outside of the Consortium and examples of the use of ISTIMES approach have been developed in the field of dams monitoring and road infrastructures diagnostics at regional level
