Abstract: A method for displaying a visual representation corresponding to a carriage capacity may include obtaining passenger data of passengers onboard a carriage of a multi-carriage vehicle. The method may further include predicting, based at least in part on the first passenger data, a number of passengers who will exit the carriage at a destination. The method may further include determining, based at least in part on the predicting, an available capacity for the carriage and generating a visual representation that corresponds to the available capacity. The method may further include displaying the visual representation at the destination of the multi-carriage vehicle.

Abstract: A dry-erase marker comprising a cylindrical housing configured to store an ink and a conic housing coupled to the cylindrical housing on a first end and having a socket on a second end. The dry-erase marker further comprising a marker head contained in the socket of the conic housing, where the marker head comprises a polymeric material and a surface topology. The conic housing is configured to transfer the ink from the cylindrical housing to the marker head, and the marker head is configured to transfer the ink to a dry-erase board by rotating in the socket.
