Beneficial effects of the utility model:

The utility model is mainly used in the linkage between urban road intersections and signal machines. Its advantage is that the road stud lights can display the information of the signal machine, allowing passing vehicles or pedestrians to judge whether they can pass through by observing the road studs. Reduce the driver's and pedestrians' observation of the road conditions below due to observing the signal lights above when they arrive at the intersection.

The dynamic road stud lights installed on the lane-dividing line send different information to the lanes on both sides, which not only strengthens the display of the lane-dividing line at night, but also enhances the functions of dividing and controlling the speed of the vehicle, and also strengthens the safety of the vehicle when entering the intersection. , choose the lane specification in the correct direction; the dynamic road stud lights installed on the crosswalk can not only warn the vehicles on the two outer sides to ensure the safety of pedestrians, but also issue signal light information to pedestrians on the inner crosswalk to remind pedestrians in time Pay attention to traffic, guide pedestrians to cross the street safely, and reduce the loss of yellow light time in pedestrian signal lights.

At the same time, it provides an energy-saving and environment-friendly road stud device with a simple structure and a two-way warning function, which improves the utilization rate of space resources at the intersection, greatly improves the traffic capacity of the intersection, and avoids congestion. The correlation algorithm of the yellow light phase of the pedestrian crossing is provided, which improves the time utilization rate of pedestrians crossing the street.

The dynamic road stud light is extremely reflective at night, which increases the vigilance of pedestrians and drivers at night, not only ensures traffic safety, but also makes the city more beautiful at night. In addition, the system can also be used as a signal light in special environments (fog, sand, etc.) to guide pedestrians and vehicles to pass through the intersection safely. Secondly, by improving the driver's attention, reduce the passing speed of cars, urge drivers to give way to pedestrians, and reduce the proportion of conflicts between people and vehicles. The system better guides pedestrians to crosswalks, and vehicles choose the correct exclusive lane; reduces the speed of vehicles approaching pedestrians, prolongs the braking distance of vehicles approaching pedestrians; increases the probability of cars giving way to pedestrians, reduces conflicts between pedestrians and vehicles, and reduces traffic accident rates.
