The indicator studs, as road appurtenances stipulated in the clause 3 of the Road Law and in the clause 37 of the Regulation relative to the structure, establishment standard of the Road, is are facilities being installed on the road for traffic safety and smooth traffic by leading the drivers’ sight especially in the night or on a rainy day through making up for supplementing the line form of the road indication installed on the road.
They convey a warning meaning to the drivers through the touching sound with the tires, and as their life cycle is comparatively long, comparing with the road indication, they have a good point saving losses and expenses of life and property.
The indicator studs, as establishments being installed for the purpose of supplementing functional paralysis following lowered recognizability, especially in the night or on a rainy day out of problems of the road indication(paint type), are defined as facilities performing a function reinforcing the road indication.
A garlic-shaped fixing device to prevent a breakaway at the anchor of the road indicator studs and construction technology of the indicator stud with a rotation-protection protrusion.
- No rotation & breakaway(pullout) and no shearing corresponds to the purpose of indicator stud installation
- Physical engineering work solving the surrounding pollution caused by the epoxy bonding agents
- Road culture creation with a new design
- Shortened construction time with the physical engineering work (competitor’s: 2~3hours , our new technology :only 1~2 minutes)
Durability
- It is designed not to be distorted or sunken. The material for easy snow removal is used.
- It is not damaged while it is being cleaned, and it is easy to repair.
Safety
- There is no phenomenon that a tire slides.
- It improves a driver's attentiveness and reduces shocks on tires.
Practicability
- There is little change in the luminosity of the glass convex lens reflector (for 5 years).
- Its retro-reflectance is remarkable.
- Foreign materials or dusts are less accumulated on it so it has good visibility.
Economic efficiency
- Its reflection effect is maintained long so the cycle of repair works is lengthened by 3 times.
- The cost for cleaning and post management is reduced.
- The cost for installation is lower than the existing plastic reflecting material.

Turning
|
A physical device of a hemisphere shape, which is to prevent the Road Stud from turning, is mounted on the bottom of the marker that is touched by thesurface of the road so its turning by the shocks of passing cars can be prevented. |
Because of chemical installation, it can turn by the shocks of passing cars. |
|
Drawing
|
Anchor bolt: The washer at the bottom plays the role of drawing the marker to the surface of the road because of the load of a passing car. |
It is chemically installed by use of epoxy adhesives so it is easily damaged and dislocated. |
|
Major material for reflector
|
Glass convection lens- Cat's eye(It has excellent reflection and its luminosity is maintained for 5~6 years.) |
Plastic reflector (luminosity is high in the early days of the installation) The luminosity is reduced by over 90% after it is cleaned 20 times. |
|
Luminosity
|
191.3mcd/LX(white)(Refer to the result of test analysis) Observational angle: 0.2 degree |
Retro-reflectance 167mcd/LX(white)(Refer to the guideline of road safety facilities and management)Observational angle and incident angle: Same as the left |
|
Solidity
|
Its dislocation is prevented. (A test report of tensile strength additionally submitted) |
Adhesives areused so the marker is often dislocated (A test report of tensile strength additionally submitted ) |
|
Safety
|
It is installed in a natural shape so it is not dislocated even by the continuous shocks of passing cars. Traffic accidents or critical damageson other vehicles by this Road Stud are prevented. |
1) Chemical adhesives are used so the marker is often dislocated by the continuous shocks of passing cars. Therefore, a traffic accident or a secondary accident can happen.
2) It is a square type so in case it is damaged, it can work as a seriously dangerous factor to vehicles.
3) After it is installed, it is necessary to control vehicle service for long hours so safety of a controller and passing vehicles is reduced.
4) After installed, the marker turns around so it gets to lose its original functions. |
|
Environmental efficiency
|
It is environmentally friendly because it doesn't use epoxy which uses bisphenol A, an environmentally hazardous material (endocrine disruptor). |
It is harmful for the people's health because it uses epoxy that uses bisphenol A, an environmentally hazardous material (endocrine disruptor). |
|
Shearing effect
|
Suppression of shearing - In case its side receives a shock by vehicle load, the shock is decentralized because it is a hemispherical shape so there is no phenomenon of shearing. |
It is a square type so when it receives a shock from a vehicle, the shock is not decentralized and instead, it is all delivered to the marker so there is a danger of a secondary accident. |
Expected Effects
- It shows great performanceand good visibility. It is effective for preventing traffic accidents and for making smooth traffic.
- Its design is aesthetic and symbolical so it made a contribution to the national 'boom' during World Cup.
- It supports the commemorative effect of the city holding World Cup, and its effect as tourism resource is maximized.
- It has remarkable durability and luminosity, and it is easy to maintain and manage so the budget for it is greatly reduced.
- It is expected to give a good image to foreign tourists and to be exported to the foreign cities that will hold World Cup.
A soccer match lasts for 90 minutes and World Cup is progressed for 30 days, but the national expectations and deep emotion, and the pride of theholding country and city will become eternal. Y4K's delicate preparedness and passion that brought the enthusiasm for World Cup to the roads have been publicized extensively and the effects have been maximized at low expense.
