Alas, do you guys have this experience when driving? The navigation just said "the front is smooth", but it was blocked tightly as soon as the turn was turned. At this time, if there is a talking display screen on the side of the road, tell you in advance that "the right-turn lane has been blocked by 300 meters", can you avoid detours? Let's talk about this todayIntelligent LED traffic induction screen, see what it can make urban traffic more "smart".
1. Can this thing really cure traffic jams? First look at three hardcore operations
Two days ago, I drove past the city center and saw with my own eyes that the road map on the screen turned from orange to red, and immediately changed the route to bypass the accident section. There are three major abilities behind this real-time updateTechnical skills：
-
Qianliyan + Shunfeng ear combination
It is not an ordinary display screen, but a "neural network" connected to the urban transportation system. The traffic data is updated every 15 seconds, which is 3 times faster than mobile navigation. Our products can doSynchronize the city's accident information within 5 seconds, 10 times faster than traditional broadcasts.
-
Automatic face-changing display
Have you seen an advertising screen that is reflective and unrecognizable at noon, right? Our screenBrightness can be automatically adjusted, the more poisonous the sun is, the brighter it will be, and it will automatically dim at night to prevent dazzling. Tested data: The brightness of sunny days soared to 7,500 lumens, 30% brighter than the ordinary screen, and it can still be seen clearly on rainy days.

Build a durable real man
Last time I saw a street sign being scattered on a typhoon day, but the screen was still moving. The secret isMilitary-grade protective design, Frozen into ice lumps at -40℃ and still work, run continuously at 80℃ for 12 hours without blackening the screen. The three-year maintenance rate of the projects we do for the expressway is less than 2% [^Company Information].
2. Selecting a device is like finding a partner, it depends on these five "match degrees".
The easiest pitfall for novices when purchasing is that they only look at the price rather than the adaptability. Remember this formula:Scenario specifications, and requirements for selection of functions。
✅ Please choose the size according to the location
At the intersection that is blocked in the morning and evening rush hour, you have to use a large screen of more than 12 square meters; it is enough to install a 3 square meters branch of the community. For example, we installed it in SingaporeP4 curved screen, it is specially designed for multi-lane turning sight line.
✅ Choose brightness by weather
It is recommended to choose 7,000 lumens or more for the northern haze cities, and the rainy areas in the south focus on waterproofing performance. Our outdoor screen test data: you can see the text clearly between 20 meters in rainy days.
✅ Functions must be able to add or subtract
A single color screen that simply points out the way is enough. To display a dynamic map, you must use a full color screen. A customer originally wanted to save money to buy a two-color screen, but later found that the real-time congestion map could not be displayed, so he spent more modification fees.
✅ Maintenance cost calculation
SelectionModular replacement model, which lamp bead is broken and which one is replaced. We have a project that has been used for five years and the maintenance fee is 60% lower than our colleagues. The secret is to use the quick-release box design [^Company Information].
✅ Don't be the sucker for energy consumption
The automatic dimming function at night can save 40% of the electricity bill in a year, which is not a small amount. Tested data: The screen with an intelligent dimming system, the electricity bill saved in ten years is enough to replace half a set of new equipment.
3. There is a mystery in the installation location, and veteran drivers are prone to falling into trouble.
Last time I saw an intersection put the screen under the shade of the tree, and the driver had to stretch his neck to look for information. Remember three correct installation postureThe Golden Rule：
-
The principle of unobstructed vision
It is most suitable to install it at 150-200 meters away from the intersection, and this distance is enough for the driver to prepare for lane change. There is a test data: the driver's decision-making reaction time is shortened by 2.5 seconds after the screen installed 250 meters away.
-
High must be able to make magic
It is just 3 meters high for urban roads, and the expressway must be carried to 5 meters. The project we did in Tokyo suffered this loss. The first version was low, and the truck driver had to lower his head to see it. Later, it increased to 4.8 meters before the problem was solved.
-
Angle follows the curve
The screen at the curve must rotate 15-30 degrees, which many people ignore. Having said that, the curved screen we designed for Seoul takes into account the turning parallax, and the information recognition rate has increased by 40% [^Company Information].
4. What will traffic look like in the future? This screen is spoiling
Now the latest induction screen is not just a display screen, it is transformingSmart terminals of transportation systems. Let’s talk about a few black technologies that are being implemented:
- AR Navigation Enhanced Edition: Use your mobile phone to scan the screen and directly output the 3D route arrow, which is ten times more intuitive than the flat map
- Breathable display: Automatically increase heat dissipation according to air humidity, and you are not afraid of short circuits during the rainy season [^ Company Information]
- Vehicle-road collaborative interface: The electric vehicle is close to the automatic display of the charging pile position. This function has been tested in our Korean project.
Last year, a customer reported that the traffic efficiency of the intersection after the installation of the induction screen has increased by 18%. This data made me feel very moved - it turns out that a screen can really change the traffic character of a city.
Having said that, choosing smart transportation equipment is like buying "invisible traffic police" for the city. You must not only see the world and listen to all directions, but also withstand the sun and rain. The happiest thing we are in this industry is hearing customers say, "Since we installed this screen, we can sleep ten more minutes during the morning rush hour." Next time you drive by the green-lighted induction screen, you might as well take a look - behind the beating numbers, there is a smart code that will smooth the blood of the city.
