1. What are the signs that glow during traffic jams?

When you are stuck on the highway, have you ever noticed the signs above your head that will change color? These are the skills of LED traffic-induced screens! ​ ​Refresh rate exceeds 1920Hz​ ​The technology allows the driver to see each text clearly at a speed of 120km/h. The most amazing thing is its brightness adjustment - it can reach 7500 nits under the sun, and it will automatically drop to 800 nits at night. This design is really considerate.

To talk about the actual effect, after the elevated system was installed in a coastal city, the efficiency of traffic during morning and evening peak hours was increased by 28%. How did it be done? All these three key skills:

• ​​Environmental adaptive system​ ​: Complete brightness adjustment within 2 seconds
• ​​Remote cluster control​ ​: Synchronous update of equipment on 30 kilometers of road sections
• ​​Fault self-test function​ ​: Automatically position the damaged module position

2. These scenes can't be stopped

Do you think the induction screen is to show "congestion ahead"? That's too underestimating it! Now even the tunnel is playing new tricks:

• ​​Fog area penetration mode​ ​: Automatically switch amber warning when encountering fog
• ​​Dynamic lane guidance​ ​: Change the arrow direction in real time according to traffic flow
• ​​Accident warning system​ ​: When abnormal parking is detected, start the flashing border immediately

In a cross-sea bridge project, engineers installed temperature and humidity sensors to the induction screen. When it comes to icy weather, the screen will have a snowflake icon and speed limit value. It is said that this design has reduced the winter accident rate by 45%. To be honest, I thought it was a black technology when I saw this kind of "thinking" screen for the first time!

4. Remember these three tips when choosing a device

1. ​​Recognize​ ​Configuration with refresh rate ≥1920Hz, dynamic screens do not drag
2. ​​Check​ ​Module splicing accuracy, do not need to be used if the gap exceeds 1mm
3. ​​confirm​ ​The performance of the heat dissipation system can work normally between -30℃ and 70℃

A purchasing director of a transportation bureau complained to me that the equipment I bought was greedy for cheap times and the circuit boards were burned during the rainy season. Later, I changed my professional equipment and I haven't even broken a lamp bead for more than three years. So, this kind of deadly road section equipment really can't save those few steel hustles!

5. Hidden benefits for on-site maintenance

Nowadays, reliable manufacturers all play a full set of services, from solution design to post-maintenance. I heard that some projects even have power supply lines, the most awesome ones are​ ​7×24-hour response mechanism​ ​——There was a problem with the equipment, and the engineer arrived at the site with spare parts for two hours.

The case of an international airport is very interesting, and the induction screen is directly connected to the flight information system. If the plane is delayed, the screen next to the runway will automatically push the boarding gate change information. This kind of cross-border integration gameplay is the true meaning of future smart transportation!

I have to say that this traffic induction screen is like installing a "smart navigator" on the road. From simple information prompts to dynamic traffic control, technology makes travel more and more secure. Next time you are in a traffic jam, you might as well look at these luminous street signs. Maybe the screen in front of you is the key to alleviating congestion!
