Abstract
Embodiments of the application relate to the field of traffic, more particularly to a method, apparatus and system for indicating a traffic signal. An embodiment is directed to a traffic signal indicating method effective on a pedestrian and/or vehicle. A traffic signal indicating system of an embodiment includes a traffic signal indicating apparatus, configured to acquire a traffic control state of a traffic management area; and a projection apparatus, configured to project first visual information for indicating the traffic control state to a first-segment pavement of the traffic management area. By projecting visual information for indicating a current traffic control state to a pavement of a traffic management area, a purpose of reminding a pedestrian and a vehicle is achieved. The projected visual information may transfer rich information. Further, it is unnecessary to modify existing traffic lights.
