Smart road studs, as the name suggests, are a kind of traffic roadblock guidance method, used to guide people to go or drive in the correct direction, prevent speeding and traffic accidents; it is mainly used in urban roads and regional high-speed networks to facilitate installation and use along the road surface. At night or in rainy and foggy weather, indicating the direction of the road, etc., smart road stud is composed of retroreflective materials, shells, solar panels, LED light-emitting tubes, information collection, car networking communication and control devices, with active light-emitting and passive light-reflecting performance luminous induction instructions , Solar battery charging, sensory information collection module, car networking communication, integrated intersection signal light linkage "five in one" visual guidance traffic safety function, usually combined with signal lights, guidance screens, signs, markings, signs, etc.
The specification structure of
NOKIN road studs is generally 100mm×100mm×20mm, and the height is no more than 25mm. There are many types of reflectors, including reflectors, reflective beads, infrared light, reflective films, etc. Due to the continuous development of solar cell technology, in recent years, in the highway and road safety protection projects implemented by the country, various high-tech traffic safety facilities and products have been favored by the industry. The wide application of these traffic safety facilities and products has played an important role in improving the safety of pedestrians and vehicles on highways and roads, and reducing the occurrence of traffic accidents. In various traffic safety facilities or products, smart road studs can clearly delineate the contours and edges of the road in rain, fog and road bends, induce the driver’s sight, interact with the vehicle information, and eliminate road problems.
①Large luminous brightness
The reflective brightness of ordinary
reflective road studs is only 300-400 MCD, while the luminous brightness of smart road studs can reach more than 2000 MCD, which is 6-7 times that of the former. High-intensity light can penetrate rain and fog at night, which is safe and effective. Provide directions for the driver.
②Active lighting, dynamic warning
Smart road studs flash at a second-level frequency at night, and human vision is more sensitive to changes, so its dynamic warning effect is very strong. Active lighting can not only avoid the interference of rain and fog to the greatest extent, but also can break away from the dependence on car lights, and the visual distance is longer and the effect is better.
③In the future intelligent vehicle road collaborative management and control, smart road studs can use functions such as vehicle and pedestrian information collection, data transmission, and Internet of Vehicles communication, including integrated vehicle flow detection, photosensitive detection, vibration detection, temperature detection, and monitoring. The road operation status and information can be grasped and understood in time to realize V2I traffic information interaction and integrated traffic signal control facilities.
Smart road stud is the basic equipment for the digital transformation of the next generation of intelligent networked facilities.
