A vehicle headrest assembly including a light source for illuminating an occupant's space. The vehicle headrest assembly includes a housing operatively coupleable to a vehicle seatback and a cover at least partially surrounding the housing. At least a portion of the housing is constructed of translucent or transparent material allowing the light source to illuminate therethrough. The light source may be an LED or an electroluminescent material. Several headrest assemblies may be incorporated into a rideshare vehicle or public transport vehicle to provide indicators to passengers of assigned seating and notify passengers that they have arrived at their destination. The illumination from the headrest assembly may further be personalized by an occupant or driver by changing the color, brightness, and other settings.

According to one embodiment, a method, computer system, and computer program product for tracking occupancy on a transit system is provided. The present invention may include receiving passenger information for passengers boarding a public transit system comprising one or more cars; counting the passengers within each of the cars of the public transit system based on the location of each of the passengers; identifying, based on the location of each of the passengers, whether each of the passengers is seated or standing; and displaying, based on the counting and identifying of the passengers, the current occupancy of each of the cars.

A method is for controlling the occupancy of the seats of one or more vehicle(s) by passengers using a control device for controlling the occupancy of the seats. The vehicle includes a number of seats equipped with a reading light. The control device includes each reading light, a control system for controlling the reading lights and a controller. The method includes an emission of at least one piece of data related to the seat toward an electronic device of a passenger of the vehicle. The piece of data is emitted using a wireless optical communication technique, which is a technique of visible light communication. The emission of the at least one piece of data related to the seat is carried out by the reading light of the seat controlled by the control system.
