Solar road studs are flashing solar cell powered LED maintenance-free lighting devices used in road construction to delineate road edges and centerlines. Embedded in the road surface, they are an electronic improvement on the traditional cat’s eyes in that they may give drivers more than a thirty-second reaction window compared with about 3 seconds for conventional reflective devices. The intense brightness of the LEDs makes them easily visible at distances of about 900 m under favorable conditions.
For intelligent solar road stud lights, in addition to a simple warning function, solar road studs can also help to realize the warning and control of driving distance. There are often rear end collision accidents on expressways because the driving distance is not well controlled. In many traffic accidents, due to not feeling the situation in front of them in time, some cars broke down and stopped, and the cars behind did not know, and the braking time was not enough, resulting in a second accident.
The perception ability of
solar road stud light and wide area Internet of things communication can also be used to warn the backward vehicles with abnormal parking. We are also studying the application of intelligent road stud in intelligent tunnel and fog warning.
Solar road stud is suitable to be installed on both sides of the zebra crossing, as a necessary component of intelligent zebra crossing.
Solar road studs can improve the traffic safety at intersections and create a safer and orderly road traffic environment for citizens. Solar road stud lights can clearly remind vehicle drivers to yield to zebra crossing, slow down, and reduce the cross street conflict between vehicles and pedestrians.
The survey shows that the buried solar road stud lights have an obvious two-way warning effect on pedestrians and passing vehicles on the crosswalk at night, and the expected implementation effect is achieved.
