A display device includes a display unit for displaying a moving body speed being a speed of a moving body, a first speed that is arbitrarily settable by a driver, and a second speed that is not arbitrarily settable by the driver. The display unit includes a display having a drawing function, and a frame member disposed to overlap the display. The display includes a display area spanning an inner side and an outer side of the frame member. The display displays the moving body speed and the first speed on the inner side of the frame member, and displays the second speed on the outer side of the frame member.

Systems, methods, tangible non-transitory computer-readable media, and devices associated with the operation of a vehicle are provided. For example, a wheel unit system can receive vehicle data including information associated with states of a vehicle. Further, the vehicle can include wheel wells associated with wheel units that are configured to generate indications associated with the states of the vehicle. The wheel unit system can also determine indications to generate on the wheel units based at least in part on the vehicle data. Furthermore, the wheel unit system can generate the indications on the wheel units. The indications can, for example, include visual indications or auditory indications.

A computer-implemented method performed for alerting the presence of one or more combination vehicles, each comprising a first vehicle unit and one or more second vehicle units and provided with a plurality of alerting units. Each respective first vehicle unit and respective one or more second vehicle units comprises a respective alerting unit out of the plurality of alerting units. The method comprises obtaining movement data indicative of one or both of a current movement or an expected movement of the one or more combination vehicles from at least one data communicating unit comprised in any one of the one or more combination vehicles. The method further comprises determining the current movement and/or the expected movement of the one or more combination vehicles. The method further comprises triggering a sound alert on the plurality of alerting units.
