In order to ensure road traffic safety, especially the safety of night driving, traffic control departments in various countries have been continuously exploring and developing traffic safety facilities. Solar road studs have played a positive role in improving road visibility with their advantages of energy saving, environmental protection, convenient installation, safety and efficiency! If you want solar road studs to play their best effect, their spacing setting is one of the important factors. NOKIN, as a solar road stud manufacturer with more than 20 years of experience, will explore the relevant issues of solar road stud spacing in depth, hoping to bring you some inspiration and help!
In simple terms, road stud spacing refers to the distance between two adjacent solar road studs on a road or lane. The seemingly simple distance setting actually plays a fundamental role in road safety. Under low visibility conditions such as night or bad weather, reasonable road stud spacing can effectively ensure the road lighting effect, clearly guide drivers to identify road boundaries and directions, and greatly improve drivers' ability to identify roads, thereby reducing the risk of traffic accidents.
As we all know, the main purpose of installing solar road studs on the road is to improve the visibility of the road and provide necessary safety guidance for drivers. If the installation spacing of solar road studs is too large, the warning effect of the road studs will be weakened, and they will not be able to provide sufficient guidance and warnings to drivers at critical moments; on the contrary, if the spacing is too close, light interference may occur, affecting the driving experience, and even causing visual fatigue to the driver.
Solar road studs are not only safety warning tools, but also part of road beautification. By scientifically and rationally planning the installation spacing, road studs can be perfectly integrated with the road environment, enhancing the overall visual effect of the road, making the road both safe and beautiful.
The brightness of road studs is one of the key factors in determining the spacing. Road studs with higher brightness have a wider range of light propagation, and the spacing can be appropriately increased; while road studs with lower brightness need to be narrowed to ensure sufficient lighting coverage.
Road conditions should not be ignored. Under ideal conditions, such as straight roads with good visibility and no obstacles, the spacing of solar road studs can reach 1 meter; but on curved roads, busy traffic sections or environments with poor visibility, the spacing must be reduced to ensure that drivers can see the road studs clearly and in a timely manner.
The spacing requirements for solar road studs are different for different types of roads. Highways have good road quality and high vehicle speeds, so wider spacing can be used; while rural roads or mountain roads have frequent turns and complex terrain, so in order to effectively guide drivers and reduce the risk of accidents, the spacing of road studs needs to be reduced.
There are many large vehicles on heavy-loaded roads, and the speed is fast, so the visibility requirements for solar road studs are extremely high. For roads with medium traffic flow and low speed, a spacing of 18 meters is more appropriate; but on heavy-loaded roads or highways, in order to ensure that large vehicles can clearly see the road studs when driving at high speeds, the spacing needs to be reduced to 12 meters.
On heavy-loaded roads, solar road studs have to withstand frequent impacts and braking pressure from heavy vehicles, so they must have high compressive strength and usually need to be able to withstand weights of 30 tons or more. At the same time, solar road studs should also have good durability and remain intact under long-term vehicle crushing. Appropriate spacing settings also help reduce the pressure on a single road stud.
Under low visibility conditions, the lighting and reflective performance of solar road studs are crucial. Whether it is rainy, snowy or foggy, road studs must be able to provide sufficient brightness. In addition, road studs of different colors have different functions. Red is often used for hazard warnings, while yellow and white are used for lane boundary markings. Choose solar road studs with good lighting and reflective performance, and increase the spacing appropriately during installation.
The installation method affects the stability and spacing of road studs. For heavy-loaded roads, embedded installation is a better choice. This method does not require screws and can ensure the stability of road studs. During installation, be careful to select the type of glue and strictly control the installation depth to prevent the road studs from shifting under the long-term rolling of vehicles.
The shape of the road will also affect the spacing of solar road studs. Straight roads have good vision, and a spacing of 6-9 meters can meet the driver's need to clearly identify signals; while curved roads limit the driver's vision, the spacing needs to be reduced to 1-2 meters to form a continuous guide sign to ensure that vehicles pass the curve safely.
Vehicle speed and traffic flow conditions determine the spacing size. On fast roads such as highways, a larger spacing is required to allow drivers to observe the road stud markings in advance, up to 9 meters; on urban roads, vehicles travel slowly and traffic starts and stops frequently, so the spacing of road studs should be controlled at 3-6 meters, especially in areas where vision is easily blocked.
Visibility affects the setting of road stud spacing. In fog, rain, snow and at night, the driver's vision is greatly limited. At this time, the distance between road studs needs to be reduced to ensure that the driver can see at least one or two road stud signals in front; in a well-lit environment, the distance can be appropriately increased.
Different weather and climate conditions have different requirements for road studs. Wind, rain and snow will affect road conditions and increase driving difficulty; in tropical areas, road studs need to be heat-resistant and UV-resistant; in cold areas, road studs that are ice-resistant and salt-resistant need to be used. These characteristics will also indirectly affect the setting of road stud spacing. For example, in severe weather, the spacing may need to be reduced to ensure safety.
Special sections and areas have unique spacing requirements. Special sections such as tunnels and ramps, as well as schools and areas with many pedestrians, need to pay special attention to the setting of road stud spacing. In tunnels, there is insufficient light, so road studs should be arranged reasonably; ramps have large terrain fluctuations, so the spacing needs to be reduced to guide driving; in dangerous areas, such as near schools, the spacing should be reduced to 0.5-1 meters to warn drivers to slow down and ensure pedestrian safety.
In lane markings, the regular spacing of 6-9 meters helps guide drivers to stay in the designated lane, regulates vehicle driving order, and improves road traffic efficiency.
On highways, edgeline and centerline road studs are used to clarify the center and edge of the road to ensure vehicle driving safety. Reasonable spacing settings ensure that these road studs are always clearly visible.
At sharp turns or curves, a spacing of about 1.5 meters can provide drivers with clearer guidance, help them pass the curve safely, and reduce the risk of vehicle loss of control.
In speed reduction or danger areas such as intersections and stop lines, a spacing of 0.5-1 meter can effectively enhance the warning effect, reminding drivers to slow down, pay attention to potential dangers, and ensure the safety of pedestrians and other road users.
The first step in installing solar road studs is to choose road studs of the right size, color and type, and make sure they meet the standards. At the same time, purchase from reliable manufacturers to get professional product selection support.
Before installation, ensure the safety of the working environment and set up traffic isolation measures to prevent traffic accidents during construction. At the same time, reserve at least 1 meter of working space to ensure the safety and convenience of construction workers.
Determine the drilling size according to the road stud type and design spacing, use chalk or paint to mark the installation location on the ground, and then use measuring tools to ensure the accuracy of the marking before drilling.
Before installation, use a high-pressure water gun to clean the road surface, use a broom to clean up debris, and then use a scraper to remove accumulated water. Ensuring that the road surface is clean and dry is the key to ensuring the glue bonding effect.
The ideal installation temperature for solar road studs is about 21°C, and installation should be avoided in high or low temperatures, strong winds or rainy days. If it may rain in the evening of the day of installation, you need to wait until the rain stops and the road surface is dry before construction.
Epoxy glue has strong adhesion and is an ideal choice for installing solar road studs. Mix the glue and hardener in proportion, stir evenly, and apply it to the installation point with a brush to ensure complete coverage.
Insert the solar road stud into the hole coated with glue, ensure that the glue fully covers the bottom of the road stud, and fix the road stud. At the same time, adjust the direction of the road stud so that the lens faces the direction of traffic. After installation, scrape off excess glue to avoid contaminating the lens.
After installation, carefully check whether the solar road stud is in the correct position, whether there is any glue residue, and whether the mark is clean. After inspection, wait for 1 hour to 48 hours according to the characteristics of the glue and the ambient temperature to ensure that the glue is completely dry before resuming normal use of the road.
Tips: Due to the different specifications of solar road studs, different road installation environments, different rules and standards of the installation areas, and different specific installation spacings, please negotiate with the supplier for the appropriate installation distance to ensure that the solar road studs can play the greatest role.
