This paper studied the use of private security to prevent terrorism and congestion accidents in the crowd-crowded situations of multi-crowd at large-scale events. Therefore, related theories were examined, and the contents were analyzed based on representative cases of large-scale event terrorism and congestion accidents abroad. For the analysis of the study, we looked at the terrorist cases of the Boston Marathon bombings in the United States in 2013, the simultaneous terrorist attacks in Paris in France in 2015, and the Easter bombings in Sri Lanka in 2019, and the congestion accidents of the Akashi Summer Festival in Japan in 2001, the Duisburg Love Parade Festival in Germany in 2010, and the Itaewon Halloween Festival in Korea in 2022. According to the study, first, it is necessary to establish a private security system so that terrorist prevention activities in multiple transport situations can be systematically carried out by actively utilizing private security in accordance with congestion and traffic guidance security tasks. Second, in large-scale events, it is essential to deploy specialized private security personnel to prevent terrorism and prepare measures for safe events. Third, it is necessary to respond to terrorism prevention and congestion accidents through real-time monitoring by introducing AI counterterrorism equipment and platforms for the prevention of multi-crowd terrorism. Fourth, by seeking ways to utilize mobile bollards, it is necessary to prevent the phenomenon of cluster stay and to prevent vehicle collision terrorism or congestion accidents.
