Abstract(in English) | Trains play an essential role in transportation in supporting people's lives. In recent years, it has become necessary to estimate the degree of congestion in each train vehicle to prevent the pandemic of COVID-19 and improve passengers' comfort. However, it is difficult to estimate the degree of congestion without violating passengers' privacy. We have developed and evaluated a system to estimate the degree of bus congestion while protecting passengers' privacy by using BLE signals. This paper used the above system to collect BLE signals on a train cooperating with Kintetsu Railway Co., Ltd. The congestion of each train vehicle is then estimated using a machine learning regression model. The results show that the MAE and MAPE can be estimated with an accuracy of 0.56 and 0.27, respectively. |
