Estimating the Number of Visitors in Tourist Attraction Facilities using WiFi Packet Sensors

Abstract

The number of visitors is a key performance indicator for quantifying the liveliness of tourist attractions. In this study, we analyzed the difference between the data obtained from Wi-Fi packet sensors and the actual number of visitors based on observation. Furthermore, we investigated the data cleaning method using the signal strength. Sensitivity analysis was conducted to set the threshold of the signal strength to clean the data according to the environment in which the sensors were installed. We then performed a regression analysis of the number of visitors using a Wi-Fi packet sensor. The results showed that the accuracy of the estimation is sufficient for monitoring the increase or decrease in the number of visitors throughout the year.
