TAIPEI (Taiwan News) — Matsu, which has no traffic lights, has begun testing a smart traffic safety system to address hazards posed by its steep, uneven terrain.

The island’s hilly landscape and sharp slopes create risky conditions at intersections and curves, where drivers often face blind spots, excessive speeds, or fail to see oncoming vehicles. The program was introduced last year to improve road safety, according to CNA.

The system uses sensor-based displays to alert drivers when other vehicles are present at intersections. Six intersections in Nangan Township are currently equipped with the technology, which triggers real-time flashing alerts whenever a vehicle enters the detection zone.

Two specialized systems on Nangan’s winding, fog-prone roads display vehicle speeds on downhill stretches. They also alert drivers to oncoming traffic on uphill curves.

The initiative is expected to be completed at all planned Nangan intersections by the end of March. If successful, the county plans to expand the system to all townships.

The plan extends to pedestrian safety near schools and other areas with poor visibility during foggy seasons. Solar-powered warning lights ensure the system operates continuously.
