Abstract

The present invention is applicable to the technical field of road traffic devices, and provides a column-type road traffic marking projection device, which includes a support column and a light generator for projecting a linear beam onto the road. The accommodating cavity of the light generator, the support column is also provided with an opening for emitting the light emitted by the light generator. The column-type road traffic marking projection device provided by the present invention provides electronic projected road markings for the road by setting a light generator capable of projecting a straight beam on the road, which not only reduces the influence of weather factors on the display of road markings, It also avoids the problem that the painted road markings are not clear due to wear.

Description

technical field [0001] The invention belongs to the technical field of road traffic devices, and more specifically relates to a column-type road traffic marking projection device. Background technique [0002] In order to ensure people's safety and ensure that vehicles travel efficiently and smoothly, people have marked traffic indicator lines on the road at each intersection, which greatly reduces the occurrence of traffic accidents and enables vehicles to move in an orderly manner. [0003] However, affected by natural and human factors or other reasons, the painted traffic markings on many roads are severely worn or covered by rain and snow, making it impossible to clearly display the road traffic markings, thus failing to provide effective instructions to vehicles and people help. Traffic markings that cannot be clearly displayed prevent drivers from switching in time to respond, which can lead to a significant reduction in traffic rates and traffic jams, or even lead t...
