1. A handrail disinfection system for vehicle with handrail, the system comprising:
a tank to store disinfectant solution;
an exudation part provided on the handrail;
one or more sensors to detect a state of an occupant riding in the vehicle;
an actuator for exuding the disinfectant solution stored in the tank from the exudation part; and
a controller for controlling the actuator,
wherein the controller comprises:
at least one memory including at least one program; and
at least one processor coupled with the at least one memory, and
wherein the at least one processor executes upon execution of the at least one program,
performing a disinfecting process in which the actuator is controlled to exude the disinfectant solution from the exudation part to a surface of the handrail when a predetermined execution condition is satisfied;
wherein the at least one memory is configured to store occupant information detected by the one or more sensors,
wherein the at least one processor is configured to execute, by executing the at least one program, a getting-off determination process to determine whether the occupant has got off, based on the occupant information,
wherein the execution condition is a condition that is satisfied when getting-off of the occupant is determined in the getting-off determination process,
wherein the at least one memory stores a set vehicle speed to a next pickup location determined based on an operation plan of the vehicle, and
wherein the at least one processor is configured to increase, by executing the at least one program, amount of disinfectant solution exuded from the disinfection part as the set vehicle speed increases in the disinfecting process.
