The combination of technology with transportation equipment, solar road studs, and smart zebra crossings can effectively reduce tunnel traffic accidents.

The intelligent solar road stud control method of tunnel lighting is based on automatic control and adopts short-term traffic flow prediction theory to realize dynamic dimming control of LED solar road stud lighting facilities in the tunnel to achieve comfortable, safe, efficient and economical traffic lighting effects , Focus on the characteristics of solar energy-saving control, reflect the requirements of green lighting, and pursue the ideal design goal of “lighting on demand”.

When the vehicle reaches a certain point at the entrance of the tunnel, within the 20° field of view of the driver of the motor vehicle, the scenery outside the cave basically disappears and begins to adapt to the dark environment inside the tunnel. The visual range of traffic at the tunnel entrance should be kept in a gradual manner, and the brightness of the environment within the visual range of traffic should not be excessively strong.

Smart tunnel solar road studs can achieve the following functions:

1. Enhanced far vision visibility at the tunnel entrance.
2. Event reminder at the entrance of the tunnel-white means normal traffic in the tunnel, yellow means heavy traffic or slow congestion in the tunnel or traffic accident in the tunnel, and red means the tunnel is closed.
3. Traffic safety guidance in the tunnel-the tunnel intelligent guidance edge markers installed in the tunnel and on the sidewall flash synchronously at a specific frequency (yellow on the left, white on the right).
4. Warning to prevent rear-end collision in the cave-dynamic wake-up warning.
5. Safety early warning, prevention and control of construction operation area-when local construction operations are carried out in the tunnel, the intelligent guidance edge marker of the tunnel can be turned on the red light early warning mode.
6. 
7. Detection and early warning of slow-moving parking incidents-when the incident is detected, the red light early warning mode is turned on to warn the subsequent traffic incident in front of the vehicle, and the traffic incident is reported to the platform at the same time.
8. Auxiliary emergency lighting.
9. Personnel emergency evacuation guidelines-in an emergency situation that requires evacuation of personnel, the system will assist in generating the personnel evacuation route plan to provide the best route guidance for the on-site personnel.

Smart tunnel entrance solar road studs and sign contour lights are used for safety lighting at the entrance of the tunnel. Intelligent control is adopted to play the role of driving safety warning and tunnel contour safety warning lights.
