South Korea is a leading country in smart city and smart transportation construction globally. Leveraging mature IT technologies and a well-developed urban infrastructure system, South Korea has continuously implemented key projects such as smart transportation ITS, vehicle-road coordination C-ITS, autonomous driving demonstration zones, and green and low-carbon infrastructure.
During the iterative upgrade of smart cities, the passive lighting mode of traditional reflective road markings has failed to meet the demands of intelligent driving, all-weather operation, and efficient human-vehicle collaboration.
Smart solar road studs, with their core advantages of zero external power supply, active lighting, intelligent interconnection, energy conservation, and environmental protection, are gradually replacing traditional road markings and have become the core supporting facilities for South Korea's smart road construction, fully empowering the upgrade of urban traffic safety.
South Korea has designated smart cities as a national core strategy. Through a 1:1 funding ratio between the national and local governments, it vigorously promotes smart transportation renovations, with the highest single grant reaching 20 billion won from the national level. The two benchmark cities, Sejong Smart Administrative New Town and Busan Eco-Suburban New Town, focus on creating intelligent traffic flow and green road systems, building a zero-accident smart commuting model.
The core goal of South Korea's smart roads is to achieve intelligent facilities, safe passage, and low-carbon operation, laying a solid hardware foundation for the implementation of autonomous driving and vehicle-road coordination.
South Korea began to lay out ITS systems in 2000, relying on the Seoul TOPIS platform to coordinate all-weather traffic data, and regularly updating national transportation plans to ensure technological iteration. Currently, it has upgraded to the C-ITS vehicle-road coordination system, combined with V2X vehicle-to-infrastructure communication to achieve data interconnection among people, vehicles, and roads.
South Korea plans to implement L4-level autonomous driving commercial applications in 2027, forcing road facilities to break away from the passive marking mode and possess active perception and intelligent interconnection capabilities.
Traditional reflective road markings heavily rely on vehicle lighting, which has obvious shortcomings in smart transportation scenarios and cannot adapt to new traffic demands. The specific pain points are concentrated in four scenarios:
Smart solar road studs are new road facilities suitable for South Korea's smart transportation and green city construction. Their core principle is simple and efficient: through built-in efficient solar panels to absorb sunlight and convert it into electricity for storage, they automatically light up at night or in low-light environments, without external power supply, and can operate independently, while supporting intelligent interconnection control.
Unlike traditional passive reflective road studs, smart solar road studs can independently emit bright light, not relying on vehicle lighting. Solar road studs are intelligently stored and dormant during the day, and automatically light up at night, with visible distances of hundreds of meters in areas without streetlights, effectively reducing night driving accidents.
The core construction goal of South Korea's smart city includes green infrastructure and low-carbon emission reduction. Solar road studs perfectly fit this development concept, significantly reducing transportation energy consumption. The intelligent solar road studs do not require wiring and pavement excavation during installation. The construction is simple and the construction period is short. They are suitable for urban renewal and old road renovation projects in South Korea. Large-scale laying can reduce the average annual power operation cost by 300-800 US dollars per kilometer, and the long-term cost performance is outstanding.
South Korea has a temperate maritime monsoon climate, with abundant rainfall, frequent fog, low temperatures and snowfall in winter, and a high proportion of mountain roads. Complex road conditions occur frequently, and traditional road signs are prone to failure. The active lighting feature of the solar road studs can perfectly adapt to the complex climate scenarios of the local area:
The new generation of intelligent solar road studs is no longer a single lighting identification device, but the terminal perception unit of the smart road. Relying on South Korea's mature IoT (Internet of Things) and V2X (Vehicle-to-Everything) vehicle networking technology, it can be connected to the city traffic central control platform.
The intelligent solar road studs can achieve remote status monitoring, brightness adjustment, synchronous flashing, and fault warning, adapting to the needs of intelligent road fine management. At the same time, it can be linked with the autonomous driving system to provide precise road position signals for vehicles, helping to implement vehicle-road collaboration.
Based on the urban road layout, traffic characteristics and smart infrastructure planning of South Korea, the solar road studs can be widely adapted to six core scenarios, specifically addressing the traffic safety pain points of different road sections.
The main roads of core cities such as Seoul, Busan and Sejong have high traffic volume and fast speeds, and the traffic pressure is extremely high at night. Installing solar road studs can clearly delineate lane boundaries and continuously guide traffic to flow orderly.
Compared with traditional markings, the active lighting studs can significantly improve the efficiency of long-distance recognition and reduce the risks of lane deviation and illegal lane changing, adapting to the all-day efficient traffic needs of main roads.
South Korea is promoting the construction of intelligent crosswalks nationwide, which is a key project for urban pedestrian safety improvement. The solar road studs are the core supporting equipment of intelligent crosswalks, with three core functions being remarkable:
This solution has been piloted and implemented in multiple cities in South Korea, effectively reducing the accident rate of vehicle-pedestrian collisions.
These areas belong to key speed-limiting and pedestrian-dense areas in the city, with slow traffic but high pedestrian mobility, and concentrated elderly and children traffic. The safety protection requirements are extremely high.
The solar road studs can be on 24-hour duty to warn at night, continuously emitting light to remind vehicles to slow down and avoid sudden pedestrian crossing risks, creating a safe and quiet community traffic environment.
South Korea has a high proportion of mountainous areas, with urban and intercity roads having continuous bends, steep slopes and cliff edges. These are high-accident areas. Traditional reflective signs are prone to failure in blind spots of bends and at night.
The solar road studs can be continuously laid along bends and slopes to form a continuous illuminated guiding line, precisely guiding the vehicle's trajectory, eliminating visual blind spots and significantly improving the nighttime traffic safety of complex mountain roads.
Tunnel entrances and highway ramps have strong light contrast between bright and dark areas, which can easily cause temporary visual blindness and judgment errors for drivers, being high accident points.
Solar studs are laid in this area to guide the lane direction in advance, buffer the visual discomfort caused by the light switch, shorten the driver's environmental adaptation time, and effectively avoid accidents such as over-speeding on the ramp and lane deviation.
South Korea is surrounded by the sea on three sides. The coastal roads in port cities such as Busan and Incheon are densely distributed. The special environment with high humidity and high salt fog in the region requires extremely high protection performance for road facilities.
The high protection grade solar studs suitable for this scenario can resist salt fog corrosion and rainwater immersion, work stably for a long time, perfectly adapt to the special conditions of coastal areas, and make up for the shortcomings of traditional facilities that are prone to aging and failure.
With the comprehensive upgrade of ITS and C-ITS systems in South Korea and the implementation of autonomous driving infrastructure, the market has put forward higher standards requirements for the performance, intelligence level, and durability of solar studs:

The global smart city is developing rapidly towards the popularization of autonomous driving, full coverage of digital transportation, AI intelligent traffic management, smart lighting upgrade, and green infrastructure implementation. This trend has completely changed the product positioning and industry value of solar studs.
Traditional road studs only undertake the basic functions of road marking and lighting warning, while the new generation of smart solar studs have become the core terminal of the smart road perception network.
Relying on IoT sensing, data transmission, and intelligent linkage capabilities, the equipment can collect real-time road traffic status, environmental data, and equipment operation data, upload to the AI traffic management platform, providing data support for traffic flow regulation, road condition monitoring, and fault maintenance. In the future, it will deeply intestud into the autonomous driving, vehicle-road collaboration system, and become an indispensable hardware carrier of smart transportation.
For various levels of smart cities and smart transportation projects in South Korea, the selection and configuration need to focus on 8 core indicators, taking into account durability, intelligence, and compliance, and adapting to local conditions and engineering standards.
