From June 3 to June 5, 2026, the 19th Shanghai International Exhibition on Traffic Engineering, Intelligent Transportation Technology, and Infrastructure (Intertraffic China 2026) will kick off in grand style. With the core theme of “Digital-Intelligent Integration, Safety-Led Development, and Empowering High-Quality Transportation Growth,” the exhibition brings together global transportation infrastructure brands, engineering contractors, international buyers, and road administration agencies, serving as one of the most influential annual business exchange platforms in the transportation industry. Among the numerous road safety products on display, Road Studs emerged as a hot topic at the exhibition due to their essential nature, high adaptability, and potential for intelligent upgrades.
As a professional traffic safety facility brand, Lightway made a grand debut at this Shanghai exhibition with its full range of core road stud products. Covering two main categories—reflective road studs and solar road studs—the brand showcased newly upgraded manufacturing processes, engineering adaptation solutions, and cross-border procurement services. These offerings address common procurement challenges for domestic and international clients, such as difficulty in selecting the right road studs, inconsistent quality, and mismatches with specific application scenarios. This article combines on-site product highlights with real-world engineering needs to comprehensively analyze the differences, advantages, and applicable scenarios of these two mainstream road stud types, providing precise selection guidance for various road infrastructure projects.
With the ongoing global transformation of smart road networks, the renovation of aging roads, and the continuous advancement of urban and rural transportation infrastructure, the shortcomings of traditional thermoplastic road markings have become increasingly apparent. Conventional road markings are prone to wear and fading, and their visibility is extremely low at night or in rainy and foggy conditions, failing to meet modern road safety standards. In contrast, road studs, as physical road guidance devices, have become standard equipment on expressways, municipal roads, rural roads, and industrial park roads due to their high durability, effective warning capabilities, and wide range of applicable scenarios.
Currently, road stud products on the market are primarily divided into two mainstream categories: passive reflective road studs and smart, self-illuminating solar-powered road studs, each suited for engineering projects with different budgets, road conditions, and climates. However, most buyers easily fall into common pitfalls during selection: blindly comparing prices, ignoring suitability for specific conditions, and failing to distinguish differences in product quality. This often leads to projects failing acceptance inspections and soaring maintenance costs. At this Shanghai exhibition, Lightway addresses these industry pain points by showcasing a full range of road studs with actual test samples. These demonstrations visually highlight the core differences between products made of various materials and using different manufacturing processes, providing a professional basis for procurement decisions.
The two core road stud series showcased by Lightway at this Shanghai exhibition precisely cover the full spectrum of needs—from high to low budgets, new and existing road networks, and urban and rural scenarios. Both products have their own advantages; there is no absolute superiority, and the choice ultimately depends on the project’s operating conditions and construction requirements.
Reflective road studs are passive warning devices that guide vehicle drivers by reflecting light from headlights. They require no power supply or energy storage, are easy to install, and require zero daily maintenance. The reflective road studs exhibited by Lightway are available in three materials—ABS plastic, ceramic, and cast aluminum—to meet load-bearing requirements in various scenarios. They typically withstand compressive loads of 15–20 tons, are wear-resistant and age-resistant, and offer exceptional value for money.
Their core advantages include low cost, ample stock availability, and simple installation, making them suitable for low-cost renovation projects such as parking lots, park roads, urban side streets, temporary construction zones, and rural roads. However, the product has a significant drawback: it relies entirely on reflection from vehicle headlights. In conditions such as heavy fog, torrential rain, or traffic-free nighttime environments, its warning effectiveness drops significantly, with a visibility range of only 50–100 meters. As such, it is unsuitable for high-risk road sections such as highways, mountainous foggy areas, or roads near water or cliffs.
Solar road studs are a core product for smart transportation upgrades. Equipped with an intelligent light control system, solar energy storage modules, and high-brightness LED chips, they automatically store energy during the day and actively emit light at night, in cloudy or rainy weather, or during fog. Their visibility range reaches 600–800 meters, with penetration through rain and fog far exceeding that of traditional reflective road studs. The full range of circular, square, and embedded solar road studs exhibited by Lightway at this event all meet the top-tier IP67/IP68 waterproof ratings and are compatible with a wide temperature range of -40°C to 85°C, withstanding the erosion of extreme weather conditions.
The products require no wiring, incur zero electricity costs, and offer an ultra-long battery life. They can operate continuously and reliably for 5–7 days during rainy or cloudy weather, completely solving the problem of lighting shortages in remote areas without power lines. Although the unit cost is higher than that of reflective road studs, their ultra-long service life of 5–8 years, zero maintenance costs, and all-weather warning capabilities make them the product of choice for smart highways, tunnel entrances and exits, high-risk mountainous road sections, and smart city road network upgrades, offering superior long-term cost-effectiveness.
Simply put, reflective road studs are the preferred choice for ordinary roads, projects with limited budgets, and short-term renovation projects; solar-powered road studs are the preferred choice for high-risk road sections, smart transportation projects, remote roads without power, and scenarios requiring long-term operation and maintenance.
Drawing on extensive experience from projects both domestically and internationally, Lightway is launching scenario-specific selection solutions at this Shanghai exhibition to help buyers quickly match products and avoid the risk of selection errors.
For high-risk sections such as smart highways, tunnels, and ramps, Lightway’s embedded cast aluminum solar road studs are the preferred choice. Their deep-buried installation ensures resistance to rolling, dislodgement, and corrosion, while providing all-weather active illumination for early warning, effectively reducing highway accident rates.
For urban arterial roads, crosswalks, and mixed-traffic sections, a combination of square solar road studs and cast aluminum reflective road studs can be installed. This approach balances daily traffic guidance with intelligent nighttime warnings, enhancing traffic order and safety on urban roads.
For remote rural county roads without grid power, as well as mountainous sections near water or cliffs, economical round solar road studs are suitable. These require no municipal power supply, enabling low-cost road safety upgrades and addressing gaps in rural transportation infrastructure.
For standard roads in parking lots, industrial parks, and scenic areas, ABS ceramic reflective road studs are sufficient to meet basic warning requirements. This significantly reduces project budgets and is suitable for large-scale, lightweight installation.
In coastal regions with heavy rainfall and high salt fog, prioritize corrosion-resistant cast aluminum road studs. These effectively resist seawater corrosion and aging, adapt to harsh high-temperature and high-humidity environments, and extend product lifespan.
Leveraging years of experience in the R&D and production of road infrastructure, Lightway’s full range of road studs is supplied directly from the source factory, ensuring end-to-end quality control from material selection and manufacturing processes to final factory testing.

We support OEM/ODM customization, allowing adjustments to light colors, flashing modes, product dimensions, and logos to meet the diverse requirements of projects in various countries.
Before shipment, all products undergo 72-hour water immersion tests, heavy-load crushing tests, and high/low-temperature aging tests to eliminate common quality issues—such as water ingress short circuits, casing damage, and brightness degradation—at the source.
The brand also offers a one-stop cross-border procurement service, covering product selection guidance, sample testing, bulk supply, customs clearance and logistics, as well as after-sales warranty, significantly reducing collaboration costs and risks for overseas buyers.
Based on frequently asked questions from clients at trade shows, we have summarized the core points for project procurement: For heavy-duty roads, prioritize cast aluminum; for standard road surfaces, ABS or ceramic materials are suitable; in rainy or coastal regions, ensure a waterproof rating of IP67 or higher and prioritize corrosion-resistant materials; in areas with insufficient sunlight, opt for high-capacity, low-temperature-resistant batteries to ensure long-lasting performance during cloudy or rainy weather. Additionally, when sourcing cross-border, prioritize direct partnerships with source factories to avoid middleman markups. Request samples in advance for on-site testing, and place bulk orders only after confirming suitability for the specific operating conditions to ensure project quality and effective implementation.
The 2026 Shanghai Transportation Exhibition clearly demonstrates that road studs are evolving toward “precision, intelligence, and longevity.” Reflective road studs are suitable for low-cost infrastructure projects, while solar-powered road studs enable high-end upgrades for smart transportation. These two product types complement each other, covering all road safety construction needs across various scenarios.
