Differences Between Digital Traffic Signs and Illuminated Traffic Signs

Differences Between Digital Traffic Signs and Illuminated Traffic Signs.

Digital fonts are usually illuminated by LEDs (light emitting diodes). There may be a small part that displays numbers or a series of numbers and letters. For example, you may see it at some airports, or it may be an e-reader with information about the upcoming flight.

On the other hand, the lighting type may include a digital type, but it may be just a sign, illuminated with a direction light from below, to make it appear to be illuminated. They usually have a sensor that turns on the light switch when it’s dark, and then reverses the process when the day comes in the morning.

Illuminated Traffic Signs

Usually, Illuminated Traffic road Signs look like this. As you can see, under the sign and on the railing outside the service platform, there are lights fixed to the railing. These lights will shine on the reflective surface to make it highly visible at night. This is a good thing, especially when you just arrive A certain area or passing by.

Digital Traffic Signs

The difference with Digital Traffic Signs is that they usually use LEDs, as mentioned before, and can look like this…

Application of Highway Digital Signs

The role of traffic signs is to indicate the characteristics of the road, prompt the driver to operate, and ensure traffic safety. The same is true on the highway. When you drive on the highway, you will see traffic signs painted with patterns or numbers on the side of the road. So, what is the difference between traffic signs on highways and general road signs?

traffic signs on highways have reflective characteristics

First, the traffic signs on highways have reflective characteristics.

Under normal circumstances, traffic signs on expressways do not use light sources that emit scattered light. Because this kind of incandescent light can cause dazzling of drivers driving at high speeds, and potentially cause accidents. Traffic signs on expressways use a new type of lighting material-reflective film. This kind of reflective film is laid on the traffic sign. If other light sources illuminate it,will reflect the light into the eyes of the driver. In summary,making the sign clear and bright. The reflectivity of this kind of reflective film is a hundred times stronger than that of ordinary paint, and the reflection distance can reach more than 1000 meters, so that the driver can find it at a long distance and ensure that the driver has a bright road ahead.

easy identification of the sign is suitable for high-speed driving

Second, the easy identification of the sign is suitable for high-speed driving.

For the setting of traffic signs on expressways, their height and physical dimensions are different from other roads. The traffic volume on expressways is large and the speed of vehicles is fast. Therefore, the design of traffic signs must ensure that drivers driving at high speeds can see from a certain distance. Clear the words or patterns on the sign board and ensure that the driver can complete the prescribed traffic behavior according to the content of the sign.

When a car drives at the speed that the highway must reach. It usually takes between 0.56 and 0.98 seconds from the discovery of the sign—recognize the sign—start to take action—the sign disappears. Of course, the length of this period of time is due to people. However, the reaction time to the information conveyed by the signs is closely related to the age, gender and driving experience of the driver. Therefore,accurate measurement can decide the size, height, and height of the logo. At the same time, it is necessary to use prescribed patterns to express corresponding content in accordance with international general rules. Such as gas stations, maintenance points, restaurants, etc.. So that drivers traveling at high speeds can quickly identify and respond quickly.

variability of the signs on the highway ensures that the highway is safe and smooth

Finally, the variability of the signs on the highway ensures that the highway is safe and smooth.

Many traffic signs set up on highways are variable pattern signal signs. For example, the road ahead is marked by changing the color of the traffic signs: green means everything is normal; yellow means congestion; red means front obstruction, so that the driver can easily find the road ahead and change lanes. There are also some variable speed limit signs, which can display different speeds from 20 km/h to 120 km/h. It can instruct the driver to position the speed at a level suitable for the maximum traffic volume . Give full play to high-speed characteristics. Especially in the climatic conditions of heavy fog, snow and icing, the variable speed limit signs play a role in providing real-time information, preventing accidents, and ensuring smooth roads.
