Abstract
A method, apparatus and computer program product are provided for controlling a functional road object. For example, at least one processor receives road sign attribute data indicating at least one attribute of a road sign and receives weather forecast data indicating a weather forecast of a location in which the road sign is disposed. The road sign includes at least one machinery for mitigating exposure to one or more weather conditions. The at least one processor identifies a state of visibility for the road sign using the road sign attribute data and the weather forecast data and generates a control signal for controlling the at least one machinery using the state of visibility.
Claims12
A non-transitory computer-readable storage medium having computer program code instructions stored therein, the computer program code instructions, when executed by at least one processor, cause the at least one processor to:
- receive road sign attribute data indicating an orientation of a road sign, wherein the road sign includes a sign board displaying sign information;
- receive weather forecast data indicating a weather forecast of a location in which the road sign is disposed, the road sign including at least one machinery for mitigating exposure to one or more weather conditions;
- identify a state of visibility for the road sign by using a machine learning model to output a level of obscureness based on the road sign attribute data and the weather forecast data, the level of obscureness indicating a degree of which the sign information displayed by the road sign is obscured, wherein the machine learning model is trained using historical data indicating weather conditions of events, orientations of signs impacted by the weather conditions during the events, and visibility of the signs during the events;
- and
- based on the state of visibility, generate a control signal configured to control the at least one machinery, wherein the at least one machinery is configured to alter an angle of the sign board based on the control signal.
An apparatus comprising at least one processor and at least one non-transitory memory including computer program code instructions, the computer program code instructions configured to, when executed, cause the apparatus to:
- receive road sign attribute data indicating at least one attribute of a dynamic road sign, the dynamic road sign including a display for dynamically displaying sign information;
- receive weather forecast data indicating a weather forecast of a location in which the dynamic road sign is disposed;
- identify a state of visibility for the dynamic road sign using the road sign attribute data and the weather forecast data;
- using the road sign attribute data and the weather forecast data, predict at least one attribute of an object that will obscure the display, wherein the at least one attribute indicate a type of object, a location of the object with respect to the display, a size of the object, a density of the object, or a combination thereof;
- and
- responsive to the state of visibility indicating obscurity, generate a signal based on the least one attribute of the object, wherein the signal is configured to cause the display to display the sign information on a portion of the display that is predicted to be partially obscured or not obscured by the object but not on one or more other portions of the display that is predicted to be obscured by the object.
