Embodiment Construction

[0038] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only the technical solutions of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0039] Please refer to figure 1 , which is a structural block diagram of the first embodiment of a traffic guidance method based on optical communication provided by the embodiment of the present invention. The solution in this embodiment mainly uses intersections for traffic guidance, and has greater application value especially in peak traffic jams....

Abstract

The invention discloses an optical-communication-based traffic guidance method and apparatus. The traffic guidance method comprises: traffic data of a traffic light in a predetermined area are obtained; according to the traffic data, a traffic jam state graph in the predetermined area is generated; light scintillation coding is carried out on the traffic jam state graph and a coded optical signal is sent by the traffic light; and according to the optical signal sent by the traffic light, the traffic jam state graph is displayed on a traffic guidance display screen. With utilization of the characteristic of the small range of the visible light communication and the light suspension characteristic of the traffic light, the traffic jam state graph is coded into an optical signal and then the signal is sent by the traffic light, so that the sending pertinence is high and the reference value for the driver is high.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a traffic guidance method and device based on optical communication. Background technique [0002] With the continuous increase of urban traffic volume, road traffic command signals play a vital role in maintaining the normal order of road traffic, improving congestion, saving energy, and reducing exhaust emissions. [0003] At present, the main traffic signal equipment on the road is traffic lights, but traffic lights can only guide the traffic flow in an orderly manner, but cannot display the traffic conditions around the current traffic lights, and cannot provide a reference for drivers to choose a driving plan. Contents of the invention [0004] The present invention proposes a traffic guidance method and device based on optical communication, which realizes the traffic state in a small range through optical communication, and provides reference for drivers to choose a ...
