The intelligent control method of tunnel road stud light is based on automatic control and adopts short-term traffic flow prediction theory to realize dynamic dimming control of lighting facilities in the tunnel to achieve comfortable, safe, efficient and economical lighting effects, focusing on the characteristics of energy-saving control. It reflects the requirements of green road studs lighting and pursues 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 road studs brightness of the environment within the visual range of traffic should not be excessively strong.

When the intelligent tunnel entrance contour road studs light plays the role of safety lighting at the entrance of the tunnel, it also uses intelligent control to play the role of driving safety warning and tunnel contour safety warning road studs light.

Realize the function:

1.The visibility of the tunnel entrance is enhanced.

2.Event reminder at the entrance of the road studs tunnel-white means normal traffic in the tunnel, yellow road studs means heavy traffic or slow congestion in the tunnel or traffic accident in the tunnel, and red road studs means the tunnel is closed.

3.Traffic road studs safety guidance in the tunnel-the tunnel intelligent road studs 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 warning.

5.Safety early warning, prevention and control of construction operation area-when local construction operations are carried out in the tunnel, the intelligent road studs guidance edge marker of the tunnel can be turned on the red light early warning mode.

6.Detection and early warning of slow-moving parking incidents-when the incident is detected, the red road studs 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.

7.Auxiliary emergency road studs lighting.

8.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.
