“…In the construction of the Marào Tunnel in Portugal [2,69] and of the transalpine Alptransit tunnels (such as the base tunnels of Loetschberg, Ceneri, and Gotthard) [12], the contribution made by the application of video camera systems, especially rear-view ones, connected to a screen in the vehicle cabin (from which the operator could have better visibility of what was happening in the surrounding area) has been demonstrated. The application of these systems, following fatal accidents caused by collisions during construction work, resulted in a better risk approach by the operators, with a consequent decrease in the risk of collisions in the tunnel (demonstrated by the fact that there were no accidents associated with such a hazard from this time to completion of construction).…”

Tunnelling and underground construction operations are often characterized by critical safety issues mainly due to poor visibility and blind spots around large vehicles and equipment. This can lead to collisions between vehicles or between vehicles and pedestrians or structural elements, causing accidents and fatalities. To improve the OS&H conditions, it is important to investigate the possible introduction of innovative techniques and technologies to reduce the occurrences and consequences of shared spaces (spaces used by both vehicles and pedestrians). For this reason, research was conducted to investigate the possible use of different technologies of anti-collision systems in tunnelling operations. First, to achieve this goal, an extensive review of the literature was carried out in accordance with the PRISMA statement to select the current techniques and technologies used by general anti-collision systems in civil and mining construction sites. Then, the operating principles, the relative advantages and disadvantages, combinations, and costs were examined for each of these. Eight types of systems and many examples of applications of anti-collision systems in underground environments were identified as a result of the analysis of the literature. Generally, it was noted that the anti-collision techniques available have found limited application in the excavation sites of underground civil works up to the present day, though the the improvement in terms of safety and efficiency would be considerable.
