El documento detalla el desarrollo de un sistema de información geográfica (SIG) para monitorear y mantener la infraestructura ferroviaria de Circumvesuviana en Italia, en el marco del proyecto SIMMI. Este SIG integra varios conjuntos de datos geográficos para facilitar la planificación del mantenimiento y optimizar las operaciones. Se enfatiza la importancia del monitoreo continuo y el análisis de interacciones entre el ferrocarril y el territorio circundante.
Support to railway monitoring and maintenance using GIS

- 2. ENEA: Italian National agency for new technologies, Energy and sustainable economic development Esri EMEA UC October 26-28, 2010 Rome • The Agency’s activities are targeted to research, innovation technology and advanced services in the fields of energy, environment and new technologies (http://wwww.enea.it). • ENEA performs R&S activities and provides agency services in support to public administrations, public and private enterprises, and citizens. • In this general framework, works the “Earth Observations and Analyses” Lab (UTMEA-TER, http://utmea.enea.it). Key activities include: − Earth Observation (Aerial and Satellite Remote Sensing): applications to environmental studies and land analysis (Classification, Land Cover/Land Use, Land monitoring and planning, Landscape metrics and indices). − GIS: applications to territorial and environmental issues (Land analysis and management, Urban planning, Decision support systems).
- 3. Summary Esri EMEA UC October 26-28, 2010 Rome • The constant and continuous monitoring of structure and infrastructure of railways and their maintenance is one of the most relevant problems in transportation. • In this framework, a specific GIS has been designed and developed to support monitoring and maintenance activities. • The GIS has been developed within the SIMMI Project (“Integrated system for monitoring and maintenance of railways infrastructures”, co-funded by Italian Ministry of Research). • The developed GIS represents an useful tool to manage and integrate numerous information necessary to plan the maintenance, organize the operations and support their efficient scheduling.
- 4. The study area The GIS has been designed and developed to support the monitoring and maintenance activities of Circumvesuviana Railway, a local public transportation company working in the Campania Region of Italy. Esri EMEA UC October 26-28, 2010 Rome
- 5. GIS main goals 1. Collect various geographic datasets to create a Geodatabase and to provide a numeric and up-to-date reconstruction of Circumvesuviana along with the areas interested by the route. 2. Analyze the interactions between the railroad and the neighboring territory. 3. Analyze the relationships between the failures checked along the track (typology and density) with the natural characteristics of the areas interested (morphology, hydrography, geology, etc...). Esri EMEA UC October 26-28, 2010 Rome
- 6. Levels of analysis - 1 1:25.000 “Overview Level”: • 1:25000 Cartography • Basic Layers (Administrative Boundaries, Hydrology, Urban areas, Road network, Railroads, etc…) • Thematic Maps (Land use, Geomorphology, Geological and hydro-geological data, etc.) Esri EMEA UC October 26-28, 2010 Rome
- 7. Levels of analysis - 2 1:5.000 “Detailed Level”: • 1:5000 Cartography; • Digital Terrain Model (DTM), 5 m spatial resolution; • QuikBird images (res. 0.60 m); • Thematic maps; • Inspection Reports of the railroad (six- monthly monitoring and maintenance); • Real-time events coming from experimental sensors displaced along the rail route (Diagnostic system). Esri EMEA UC October 26-28, 2010 Rome
- 8. Railway–Territory Interaction • Analysis of the relationships between the failures checked along the track (typology and density) with the natural characteristics of the areas interested (morphology, hydrography, geology, etc...) Esri EMEA UC October 26-28, 2010 Rome
- 9. Linear referencing In this case the dynamic segmentation process has allowed to use multiple set of attributes (about rail geometry and characteristics, events checked, territory...) and to associate them with a selected portion of the track. In this way, by means of specific GIS procedures, it has been possible to analyze the reciprocal interaction between territory and railway. Esri EMEA UC October 26-28, 2010 Rome Linear referencing is the method of storing geographic locations by using relative positions along a measured linear feature. It is used to associate multiple sets of attributes to portions of linear features (i.e. railroad) without requiring that underlying lines be segmented (split) each time that attribute values change.
- 10. Monitoring and maintenance activities Inspection Reports of the railroad (six- monthly carried out): check to artifacts (bridges, underpasses, structures, etc…) and to technological infrastructure (devices, etc…) Data coming from Reports has been processed and stored into Geo- database: all the events reported are associated to the respective portion of the railroad.

- 12. Interaction analysis: Territory vs Railway Case study: Anomalies, damages and/or failures detected along the railroad and due to water infiltrations (localization by means of dynamic segmentation and spatial analysis). Esri EMEA UC October 26-28, 2010 Rome Exploiting ArcGIS geoprocessing tools, jointly with statistical analysis, it has been possible to highlight vulnerable portions of the track, where the failures are more frequent because of local problems (landslides, water damages, etc...).

- 14. GIS & experimental diagnostic system integration Collection of events regarding devices anomalies or bad functionality GIS receives data about damages or anomalies of devices displaced along the track and store them into Database. The events could be real-time acquired by specific sensors (Experimental diagnostic system). WEB-GIS Esri EMEA UC October 26-28, 2010 Rome
