Can LS-68A Internally Illuminated Road Studs Improve Nighttime Safety Without Increasing Speed?
Can LS‑68A Internally Illuminated Road Studs Improve Nighttime Safety Without Increasing Speed?
A recent study titled “Solar-Powered Active Road Studs and Highway Infrastructure: Effect on Vehicle Speeds” reveals a compelling insight: solar-powered active road studs improve night-driving safety without encouraging faster speeds.
The research, conducted on a 20 km section of UK highway over two years, found that:
- Vehicle speeds did not increase after installation.
- In 70 mph zones, drivers slowed down by ~1 mph at night.
- Driver feedback highlighted improved visual guidance and confidence, especially in curves and dark zones.
This evidence strongly supports the application of active LED road studs like Lubao Smart’s LS‑68A for increased visibility, safety, and comfort — without compromising speed control or compliance.
LS‑68A Internally Illuminated Raised Pavement Marker (IIRPM）

How LS‑68A Aligns with the Study’s Findings？
| Study Observation | LS‑68A Supporting Feature |
|---|---|
| Speed decreased in darkness | Clear visual lane guidance improves awareness and alertness |
| Driver confidence increased on curves & bends | Dual-side LEDs offer 180° lane and path visibility |
| No speeding behavior observed post-installation | Subtle visual cues that guide, not encourage aggressive driving |
| Widely accepted by cautious & elderly drivers | Reliable illumination in poor lighting conditions increases comfort |

Where to Install the LS‑68A for Maximum Impact？
- Highway curves, tunnels, approach zones, and exit ramps
- Rural dark roads or pedestrian crossings lacking overhead lighting
- Merge lanes and intersections with a history of nighttime confusion
- Temporary diversion lanes in construction or maintenance zones
When used in flashing mode, it alerts; in steady mode, it guides — both without contributing to speeding behavior.
✅ Why Choose LS‑68A?
- Tested according to ISO 9001:2015 QMS
- Approved for long-term embedded installation
- Designed and developed by Lubao Smart LLC (USA)
- Manufactured and assembled by Lubao Smart Traffic Co., Ltd.
