Why do tourist attractions need passenger flow statistics? What's the point?

Due to the relevant provisions of the Tourism Law, the current limit system is implemented in 5A-level scenic spots, so the tourist attractions begin to use passenger flow statistics. As for the introduction of Yaliangmenbao, the passenger flow statistics use video to show the passenger flow in and out of the scenic spot in real time, which avoids the stampede accident caused by dense passenger flow. In addition, it is also about the analysis of the profit data of scenic spots and the overall income situation to measure the return on investment of funds.
