The traffic guidance display screen should be clearly visible under various lighting conditions.

When the sun is shining directly during the day, the screen should be bright enough for the driver to see the information on it clearly.

At night or on cloudy days, it should not be too glaring. Otherwise, it will dazzle the driver’s eyes.

The three-color LED display screen is quite suitable. It has high luminosité and can automatically adjust according to the environment, so it will not become a “bulb” at night.

Moreover, it must be able to display various texts, numbers, and symbols, just like the road signs we usually see. The content must be accurate and clear, and there must be no blur or ghosting.

If there are some dynamic effects, such as a scrolling display or gradient display, it would be even better so that the information can be more eye-catching.

The traffic guidance display screen cannot be a “rigid” thing, and it must be able to update information at any time.

For example, if the traffic conditions change or an accident occurs, the control center must be able to remotely update the content of the display screen through the network immediately without going to the scene to operate.

Moreover, it is best to be able to be operated manually locally, for example, when there is a problem with the control center network, the on-site staff can also quickly adjust the information.

In addition, the brightness adjustment of the screen is also very important. It cannot be always the same brightness, otherwise it will be too dark during the day and too bright at night.

It is best to be able to adjust it automatically according to the light, or the staff can adjust it manually.

If the screen is broken, it can also automatically alarm and tell the problem to the control center, so that the maintenance personnel can repair it in time without delay.

Most traffic guidance display screens are installed outdoors, and wind, rain, sun and rain are common, so it must be strong enough.

Waterproof and dustproof are basic requirements, otherwise the screen will easily break down in a heavy rain or sandstorm.

Moreover, it must be able to withstand severe cold and heat and can work normally from dozens of degrees below zero to high temperatures.

Its life must also be long, and it cannot frequently have problems after a short period of use.

For example, the LEDs on the screen should be durable enough, with only a few broken in a year.

The average trouble-free time of the entire screen should be as high as tens of thousands of hours, so that it does not need frequent maintenance and affect the display of traffic information.

Nowadays, information security is very important, and traffic guidance display screens are no exception.

It must have strict equipment registration and authentication functions to prevent unauthorized people from changing information at will, such as preventing people from playing pranks or maliciously tampering with traffic information.

Moreover, its various interfaces (such as USB and network interfaces) must also be strictly managed, and you cannot just plug in a USB flash drive to download things to prevent viruses or hacker attacks.

The control cabinet must also have a door lock to prevent it from being opened casually, and the data and equipment inside must be able to be remotely monitored and managed so that problems can be discovered and handled in time.

Although the traffic guidance display screen is mainly used to display information, its appearance cannot be too ugly. Its corners must be smooth and free of burrs. Otherwise, it may hurt people.

It should also be convenient to install. It is best to install it directly on the roadside pillars, and the height should be appropriate so as not to affect pedestrians.
