In your opinion, why are there no lights on the highway?

In the case of street lights, drivers are more lax at night and are prone to accidents. On the contrary, when there are no street lights, the driver has less interference and a concentrated line of sight, which can reduce the accident rate.

The street lamp used on the highway has poor illumination, and it is scattered light, and the street lamp and the strong windshield of the car are easy to form a virtual shadow, which affects the driver's line of sight, and will dazzle the driver in long-distance driving, and is easy to cause accidents. Therefore, there are no street lights on the highways.

I think the main reason is that the cost is too high, the street lights are powered by buried cables, and the construction cost of the power supply lines of the street lights is very high for the highway more than three kilometers away from the power point. As the number of lines increases, a booster system is required. That is to say, not only the power consumption of street lights, but also the power consumption of the transmission line is also very large, and auxiliary facilities must be added, so many highways and suburban roads in China are not installed with street lights.

That is the highway has a perfect reflective sign system, including hot melt reflective markings, film reflective contour markings, luminous ground nails, etc., under the illumination of vehicles, can reflect the traffic lane indication markings, roadside contours, lane dividers and ** separator outlines, no need for street lighting.

There is a light, G60 on the anti-fatigue channel to understand, it's cool.

According to statistics, in 2015, the total mileage of China's highways has 10,000 kilometers, if all the street lights are installed, the cost will be very large, and the electricity expenditure is also a lot, which is not conducive to environmental protection. Selective road section installation is also not realistic, because there is a lot of uncertainty in the flow of high-speed traffic. What's more, there is much less traffic at night than during the day, and the waste of energy will be serious.

The more construction will follow, the management cost will also come up, the maintenance and labor expenses will be very large, counting some remote road sections, inaccessible, the maintenance cost will be higher. So with all this in mind, there are no lights on the highway.

Generally speaking, the illumination of street lamps is discontinuous and uneven. For high-speed vehicles, this alternation of light and dark can cause optical illusions very dangerously and can quickly cause eye strain. Moreover, the general street lamp has poor illumination, and the light is scattered light, which will make the driver "dazzled" in long-distance driving, resulting in driving safety hazards.

In addition, when the outside lighting is insufficient, vehicle headlights can provide safer lighting for drivers.

If street lights are installed over such a long distance, the cost will be very high. The early construction and later maintenance are all money, and this number may not be as simple as everyone thinks, and it is more difficult to do.

The main reason for the highway is not to set up street lights is to save energy, and the highway has a complete reflective sign system, including hot melt reflective markings, film reflective contour markings, luminous ground nails, etc., under the illumination of vehicles, it can reflect the traffic lane indication markings, roadside contours, lane dividers and ** divider contours, and there is no need for street lighting at all.

Because there is no zebra crossing or intersection across the road, it is just a road for one-way vehicles, and all cars have lights, so lights are not needed.

In fact, I think it's mainly for safety, just imagine, the road is full of lights, which will undoubtedly cause a kind of damage to the driver's eyes, plus the light source of the street lights on the highway is discontinuous, and the distance is not the same. If the driver drives on the highway at a constant speed, there is a certain fixed rhythm of the light and dark street lights, and this rhythm will not only give people a sense of dizziness, but also have the effect of "hypnosis" for a long time alternating between light and dark, which undoubtedly increases the danger of driving at night.

After years of development, the expressway has spread all over the country's large and medium-sized cities, bringing great convenience to our travel. However, all highways outside the city do not have street lights, which is due to the following reasons: Cost factor, of course, the number of night trips is relatively small, if you want to install street lights, workshop routes, installation of lamp holders, plus labor, damage to later maintenance, etc., it will cost a lot of financial revenue, which is not coordinated with economic and social values, so there is no need to install street lights.

Secondly, the installation of street lights affects the safety of driving at night. The speed of the car on the highway is more than 80 km/h. After the street lights are turned on, there will be intermittent and discontinuity, resulting in the alternation of light and dark on the road surface, which seriously interferes with the driver's vision and increases the possibility of traffic accidents.

Finally, temporary airfields in combat readiness are available on highways, and aircraft can be forced to land in an emergency, and the installation of street lights can adversely affect the normal take-off and landing of aircraft, or even delay the landing of aircraft.

China's highways stretch for tens of thousands of kilometers, ranking first in the world. Although it is charged, it also brings great convenience to our trip. But the drivers who drove at night noticed something strange.

Once out of town, the highway is pitch black and unlit. Street lights are installed only to make it safer and more convenient for non-motorized vehicles and pedestrians; Pedestrians and non-motorized vehicles (including motorcycles, tractors, tricycles, etc.) are not allowed to drive on the road.

Therefore, there are no street lights on general highways. First of all, we are indeed right to have such an idea, the total mileage of highways in our country will reach 10 million kilometers Fengpei, if you say that the entire section of the road where street lights are installed, the construction cost is conceivable. Street lights require electricity, which is also a long-term expense.

Especially on some of the more remote highways, the randomness of the traffic flow is quite large, and it is obviously not practical to install a full line, and it will cause a lot of energy waste. /n/n

Because if street lights are installed on the highway, it may have a vertigo effect, so the judgment is particularly sun-mold is easy to cause dizziness of the car owner, and eventually leads to improper operation and accidents.

For the sake of safety, we will not install street lights. If there is some dark alternation for a long time, you will feel particularly drowsy, which has a hypnotic effect.

Car owners who shuttle back and forth between the city and the highway may find such a phenomenon, there is a street light in the city every once in a while, so that it is convenient to provide the driver with a good driving vision at night, and it is safer to drive, but there is no street light on the highway, which is also very confusing to many people. What's going on with this repentance?

As we all know, China's highways cover a very wide area. By 2019, the number of expressways reached 10,000 kilometers, ranking first in the world. For such a long expressway, if street lights are installed like a city, according to statistics, the shortest expressway in China is also 300 kilometers long.

If street lights are installed every 20 meters, at least 15,000 street lights will be needed for this section of the road. If the cost of a single street lamp is not less than 1,000 yuan, the construction of street lamps alone will be as high as 15 million, and there will be power supply and maintenance of street lamps in the later stage. Or the laying of solar panels, coupled with the randomness of the traffic flow of highway routes, if the installation of street lights for a small number of cars to pass, it will inevitably cause a huge waste of manpower, financial resources and resources.

On the other hand, for the safety of the majority of car owners, the light of street lighting is uneven and discontinuous. If street lights are installed, the speed ratio of high-speed boarding will be faster, and this alternation of light and dark can easily cause a visual error, thereby increasing the hidden danger of driving. In addition, the poor lighting of street lights and the scattering of light make it easy to dazzle drivers when driving long distances, resulting in eye fatigue and is very dangerous.

In addition, pedestrians and non-motorized vehicles are not allowed on the highway, the highway is flat and wide, there are no obvious potholes, the road is in good condition, and there are no street lights. Generally speaking, although the highway has a high safety factor, it is still necessary to drive cautiously at night and take a break in the service area every two hours. After all, safety is the most important thing.
