Marking device, system, and control method

A system comprising:

• a marking device including a plurality of pedestrian light sources on a roadway and that emits light in at least one of a first direction and a second direction along a width direction of the roadway, and a plurality of vehicle light sources on the roadway and that emits light in at least one of a third direction and a fourth direction along an extension direction of the roadway;
• a first sensor configured to detect that a pedestrian is going to cross the roadway;
• a second sensor configured to detect that the vehicle on the roadway;
• and
• a control device configured to
• communicate with the marking device to separately control the pedestrian light sources and the vehicle light sources,
• light the pedestrian light sources to mark a first pedestrian crossing to be visually recognized by the pedestrian,
• light the vehicle light sources to mark a second pedestrian crossing to be visually recognized by a driver of a vehicle on the roadway,
• cause at least the first pedestrian crossing to be marked when the pedestrian who is going to cross the roadway is detected, and
• cause both the first pedestrian crossing and the second pedestrian crossing to be marked when the pedestrian who is going to cross the roadway is detected and the vehicle is detected on the roadway.

A control method of a marking device that includes a plurality of pedestrian light sources on a roadway and that emits light in at least one of a first direction and a second direction along a width direction of the roadway, a plurality of vehicle light sources on the roadway and that emits light in at least one of a third direction and a fourth direction along an extension direction of the roadway, a first sensor configured to detect that a pedestrian is going to cross the roadway, a second sensor configured to detect that the vehicle on the roadway, and a control unit configured to separately control the pedestrian light sources and the vehicle light sources, the control method comprising:

• lighting the pedestrian light sources with the control unit to mark a first pedestrian crossing to be visually recognized by the pedestrian;
• lighting the vehicle light sources with the control unit to mark a second pedestrian crossing to be visually recognized by a driver of a vehicle on the roadway;
• causing at least the first pedestrian crossing to be marked when the pedestrian who is going to cross the roadway is detected;
• and
• causing both the first pedestrian crossing and the second pedestrian crossing to be marked when the pedestrian who is going to cross the roadway is detected and the vehicle is detected on the roadway.
