Everyone thinks it is very reasonable that there are no street lights on the highway, but no one knows the reason. There are many countries in the world, but very few have installed streetlights on the highway.


The first reason why street lights are not installed on the expressway is that it is really not necessary. There are no pedestrians or bicycles on the expressway, and the road surface is very flat.


Turning on the high beams during driving is also enough to check the road conditions and roadside signs. In addition, 18% to 25% of glass beads are added to the road marking paint, so the road markings can reflect light so that drivers can see more clearly.


It is not completely without street lights on the expressway, there are still street lights in tunnels and bridge decks. There are regulations for this. In the "Code for Design of Highway Tunnels", it is pointed out that tunnels with a length greater than 100 meters must be equipped with lighting equipment.


In addition to the fact that street lights are really not needed on highways, there is another reason that although street lights can provide drivers with good lighting effects at night, they are not completely harmless. Presumably many people are reluctant to pass through tunnels when running at high speeds. One of the reasons is that the lights are very dazzling.


As a diffuse light source, street lamps are very bright when you approach them, and become dark when you leave them. If you look at them flickering for a long time, you will feel visual fatigue. A section of the tunnel makes us feel uncomfortable. Wouldn't it be more dazzling if streetlights are laid for hundreds of kilometers on the highway?


Some people say that the absence of street lights on the expressway is a lack of money in the final analysis. We have to admit that this is a fact. At present, only Belgium and the emirate of Abu Dhabi have achieved full coverage of highway lighting. The reason why street lights can be laid on highways is because of the small land area and the money.


If lighting equipment is laid on all highways, the initial infrastructure costs and later maintenance costs are not small. If the cost is transferred to the car owners, the increase in high-speed tolls will also have a great impact on many car owners and logistics companies.


In recent years, many highways in big cities have gradually begun to be equipped with lighting equipment, but no matter whether there are street lights or not, we still hope that car owners and friends should pay more attention and drive safely when driving on the highway.


The country with the brightest street lights in the world - Belgium


Belgium is one of the only countries in the world that has bright streetlights on all highways. There is a bright street light every 30 meters, and its street light density is the highest in the world.


Therefore, whenever night falls and the lights turn on, the roads in Belgium are connected by street lights, like long glowing dragons.


Good road lighting makes Belgium the only country in the world that does not need to turn on headlights when driving at night. Drivers driving under the illumination of such bright street lights are not only relaxed and chic but also do not easy to get tired.


According to experts, the good and perfect road lighting in Belgium benefits from its direct welfare system.


According to this system, while people have high incomes, they must also pay high taxes. The government spends all of these taxes on public utilities such as road facilities, urban construction, and social welfare. Let people see, touch, and fully enjoy.


Today, bright and comfortable road lighting not only brings convenience to Belgians but also wins a reputation for the Belgian country. Streetlights have become the most prominent symbol of Belgium.
