Walking Safety Should Not Be Ignored
We believe the value of a smart city lies not in the technology itself, but in its ability to make every person walk with peace of mind.
Real-time synchronization ensures the remaining seconds displayed on traffic lights are broadcast instantly to the user's app via audio.
Utilizing advanced communication protocols for stable, low-power connectivity that seamlessly integrates with existing traffic controllers.
Users aren't just passive receivers. The system allows two-way communication, enabling users to request more crossing time via the app.
When a visually impaired person stands at an intersection, their phone receives a broadcast from the CTR-3204 unit. The app provides:
Precise audio countdown of remaining seconds.
Directional guidance for safe crossing.
Active safety button to extend green light duration.
The heart of the system is the CTR-3204, a robust hardware unit installed at intersections.
It receives traffic data via LoRa communication and broadcasts it via iBeacon to nearby smartphones. It also listens for Bluetooth signals from user phones to trigger traffic controller commands.
| Communication | LoRa (Long Range) + Bluetooth (iBeacon) |
| Integration | RS-485 / Digital I/O |
| Power | DC 12~24V Low Consumption |

We offer seamless integration with existing traffic control systems. Let's build a barrier-free environment together.
