| Popis: | With continued economic development, movement and logistics to various parts of the country are increasing. Consequently, long tunnels in the mountains and the large city underground road tunnels under construction have become increasingly important. Further, the escalating number of road tunnels has resulted in the deepening of tunnels and an increase in the number of long tunnels. Because it is highly possible fora traffic accident inside a tunnel to cause further accidents, various safety improvement measures should be prepared. To resolve the problem, dualizing the emergency power of CCTVs (which perform the major functions of tunnel safety) is proposed for application in a plan to improve safety. This plan improves safety control inside the tunnel and contributes to its maintenance. This study was prompted by the expressway tunnel accidents that occurred in the Central Region Expressway in October 2015 and February 2016. The safety security system based on the dualization of the emergency power inside the road tunnel is being monitored, with its application in some tunnels as the pilot project of an actual lab concept. Moreover, measures on safety control inside the road tunnel can be prepared through the monitoring. |
