LED/LD photo-communication-based crosswalk line and design method thereof

Abstract

The invention relates to an LED/LD photo-communication-based crosswalk line and a design method thereof. The crosswalk line comprises a pedestrian LED/LD light source and an automobile driver LED/LD light source which are inlaid on the crosswalk line, an LD laser wireless communication device as well as a microprocessor, a memorizer, a wireless information acquisition device and the like which are arranged on the crosswalk line. According to the design method, the characteristics that LED/LD is low in energy consumption, low in cost, directional in luminescence, high in light-emitting efficiency and easy in light-emitting pattern formation are utilized; LED/LD light communication is arranged in the crosswalk line, so that the characteristics that the pattern is visible in daytime and is striking at night are achieved; and particularly at night, even if under the condition that a street lamp does not exist or the street lamp is gray, the crosswalk line and the pattern can be clearly visible, and pedestrians and vehicles are safe. The crosswalk line provided by the invention can be applied to T junctions, cross roads, flyovers and the like, and also can be applied to speed bumps and the like.

Description

technical field [0001] The invention belongs to the technical field of traffic control and traffic safety, in particular to a pedestrian crossing line based on LED / LD optical communication and a design method thereof. Background technique [0002] Pedestrian crossing refers to the part of the sidewalk connecting the two sides of the street, which is marked with lines and used exclusively by pedestrians when crossing the street. Pedestrian crossings are mostly located at intersections and sometimes in the middle of blocks. There are often white solid line signs on the sidewalk part, which is called a pedestrian crossing line. It is one of the common signs in urban traffic. Because it resembles the stripes on a zebra, it is also called a zebra crossing. The law stipulates that pedestrians crossing the road must follow the crosswalk line, which can ensure the safety of life and property. [0003] As early as the ancient Roman era, horses and carts were mixed on some streets i...
