Automatic Passenger Counting (APC) systems in public transport are useful in collecting information that can help improve the efficiency of transport networks. Focusing on video-based passenger counting, the aim of this study was to evaluate and compare an existing APC system, declared to be highly accurate (98%), with a newly developed low-cost APC system operating under the same real-world conditions. For this comparison a low-cost APC system using a Raspberry Pi with a camera and a YOLOv5 object detection algorithm was developed, and an on-field experiment was done in collaboration with the pub-lic transport companies operating in the cities of Turin and Asti, Italy. The ex-periment shows that the low-cost system was able to achieve an accuracy of 72.27% and 74.59% respectively for boarding and alighting, while the tested commercial APC system had an accuracy, respectively, of 53.11% and 55.29%. These findings suggest that current APC systems might not meet expectations under real-world conditions, while low-cost systems could potentially perform at the same level of accuracy or even better than very expensive commercial systems.

Abstract

Automatic Passenger Counting (APC) systems in public transport are useful in collecting information that can help improve the efficiency of transport networks. Focusing on video-based passenger counting, the aim of this study was to evaluate and compare an existing APC system, declared to be highly accurate (98%), with a newly developed low-cost APC system operating under the same real-world conditions. For this comparison a low-cost APC system using a Raspberry Pi with a camera and a YOLOv5 object detection algorithm was developed, and an on-field experiment was done in collaboration with the pub-lic transport companies operating in the cities of Turin and Asti, Italy. The ex-periment shows that the low-cost system was able to achieve an accuracy of 72.27% and 74.59% respectively for boarding and alighting, while the tested commercial APC system had an accuracy, respectively, of 53.11% and 55.29%. These findings suggest that current APC systems might not meet expectations under real-world conditions, while low-cost systems could potentially perform at the same level of accuracy or even better than very expensive commercial systems.
