VISIVIA research project: Set-up of the VISIT (Visual Inspection for Safety-deficit Identification and Triage) methodology and use of drones for inspection of existing bridges near the road SS13 "pontebbana"

This work illustrates the first tests of drone use in the implementation of the VISIT methodology (Visual Inspection for Safety-deficit Identification and Triage) for bridges safety surveillance purposes. Tests were organized at the University of Udine with collaborative efforts of the SPRINT-Lab researchers, ANSFISA experts and drone pilots of Italian National Fire Corps. The execution took place on three bridges near the road SS13 "Pontebbana". The research and test outcomes confirm that the activities developed with the VISIT method through the use of drones provide high inspection details without requiring traffic restrictions or the use of expensive equipment and ensuring safety conditions for road users and bridge inspectors. The test activities also focused on the need for synergistic work between bridge inspector and drone pilot, evidencing the potential of modern technologies that allow the reconstruction of highly detailed three-dimensional scenarios. The work concludes by highlighting the outcomes of the comparative test emerged during the debriefing critical discussions among all participants

VISIVIA research project: Set-up of the VISIT (Visual Inspection for Safety-deficit Identification and Triage) methodology and application on a prototype case on the road SS13 "pontebbana"

The purpose of this work is to describe the development of the VISIT methodology (Visual Inspection for Safety- deficit Identification and Triage) and illustrate the first prototypal tests on a real case of the computerized inspection system. The tests were organized at the University of Udine - SPRINT-Lab Safety and Protection Intersectoral Laboratory, and took place on the SS13 "Pontebbana", a key connection road in the North-Est of Italy. This work illustrates how the new developed VISIT tools permit to acquire and manage the inspection data, in order to process and summarize them in a standardized way for a situational overview dashboard of the National Agency for Safety of Railway and Road Infrastructures (ANSFISA). The VISIT methodology aims to highlight the need for improving road infrastructures safety by the managing entities. The results of the prototype tests were positive. Therefore, the project moved on to the subsequent phases, which will allow the definition of the supervision and intervention request strategies in a contextualized manner, through a unique and innovative system. This system will support ANSFISA in its objectives of vigilance aimed at improving the levels of safety and regularity of road traffic on the Italian network
