Power-saving evaluation of the demand responsive intelligent bus stop system using a camera

In this paper, we propose the power saving method of the intelligent bus stop for demand responsive bus. To save the power of the intelligent bus stop, we use normally off computing to execute its function only when users use it. When we practice a demonstration experiment in Nanae town, the error rate of pyroelectric sensor to detect users is 37 %. The power consumption of communication function to communicate with bus server is the biggest of all functions in it. To save the power consumption, we reduce the communications to the server by improving detection using a camera.
