New Method to Calculate Exit Flow Based on RFID Technology

Abstract

Common methods of obtaining the pedestrian movement parameters include the video processing and the manual statistics. Nevertheless, both the two ways may be complicated and time consuming. In this paper, we propose a new method to calculate the flow and count the number of pedestrians of exit-selection based on RFID technology. The proposed method is validated by comparing with the results obtained from the two different methods, the RFID method and the video processing. It is found that the identified rate of the reader reaches 90% and about 90% of the errors of exit time are less than 0.075. Besides, all the errors of exit time are less than 0.1. About 80% of the errors of exit flow are less than 0.1 and 90% are less than 0.2. It is also verified the new method is much easier than the traditional video processing and more time-saving than the manual process. It is hoped that, more data of pedestrian movement parameters can be easily and quickly extracted through the method proposed in this study.
