Background The road intersection is a high incidence area of traffic accidents, and particularly when the sight line is poor at night, the occurrence rate of the traffic accidents is obviously increased. The existing road intersection mainly improves traffic safety by arranging traffic lights, but the mode has the defects of high investment cost and low traffic efficiency, and is difficult to adapt to the requirements of 400 thousands kilometers rural roads in China on economic and efficient traffic safety improvement schemes. In the driving process of a driver, the pavement marking is a primary visual concern. If the crossing transverse pedestrian marking can be designed to intelligently judge the human-vehicle interference factors, dynamic flickering is realized when human-vehicle interference exists, warning and guiding are carried out from a first visual angle of a driver and a pedestrian, and the traffic safety of the crossing can be greatly improved. However, the prior art has the following defects that firstly, the reflective marking emits light by means of vehicle lamplight reflection, the reflective marking is invisible to the vehicle, namely, a driver can see the reflective marking and pedestrians are difficult to perceive the reflective marking in darkness, the reflective effect is obviously reduced after rain and fog weather and road surface water discharge, the visibility is poor, secondly, a dynamic warning marking can be formed by an independent laser warning device, continuous road guidance is not suitable to be provided due to the inadaptability of laser to human eyes for a long time, and thirdly, the independent self-luminous mark (such as a road mark made of long-afterglow energy storage luminescent material) can continuously emit light at night, but has the problems of low energy storage efficiency and insufficient brightness, and cannot form dynamic warning to an incoming vehicle.
