Why are there no street lights installed on the highway?

Why are there no street lights on the highway?

There are several main reasons why street lights are not installed on highways:

First of all, expressways are built to provide high-speed, safe, and smooth traffic passages, and their main purpose is to facilitate vehicles to travel quickly and reduce traffic congestion. Therefore, the design and construction of highways focus on the safety and smoothness of vehicle driving, rather than providing lighting services. Installing street lights increases construction and maintenance costs, as well as energy consumption, which is not in line with the design concept of the highway.

Secondly, the traffic flow on the highway is large, and the vehicle travel speed is fast, if street lights are installed on the highway, it may cause interference and visual fatigue to the driver, increasing the risk of traffic accidents. When driving at night, drivers rely primarily on the vehicle's headlights and road signs for navigation, rather than relying on street lights. Therefore, not installing street lights on the highway can reduce driver interference and improve driving safety.

In addition, the design and construction of highways follow certain standards and specifications, which include the reflective performance of the pavement and the reflective performance of the markings. These designs can be reflected through the vehicle's headlights at night, providing sufficient illumination to allow the driver to clearly see the road and signs to ensure driving safety. As a result, there is no need for additional street lights on the highway to provide illumination.

Finally, the construction and maintenance of highways requires a lot of capital and human resources, and if street lights are installed on highways, it will increase maintenance costs and workload. In addition, the maintenance and replacement of street lights also need to occupy the road, which may have a certain impact on traffic. Therefore, in order to conserve resources and improve efficiency, street lights are generally not installed on highways.

In summary, the lack of street lights on highways is due to safety, economy, and efficiency considerations. Highways are designed and constructed with a focus on the safety and smoothness of vehicle travel, rather than providing lighting services. Drivers rely primarily on the vehicle's headlights and road signs for navigation, rather than relying on street lights.

In addition, the highway has been designed and constructed with the needs of night traffic in mind, providing adequate lighting through the reflective performance of the road surface and the reflective performance of the markings. Therefore, not installing street lights on the highway can reduce driver interference and improve driving safety.

Because the highway is very long, if all the street lights are set up, the cost is too great, and in the process of no vehicle, the street lights have been on will also cause a large amount of extravagance and waste, and it is very troublesome to repair, and the highway road surface is in good condition in terms of safety performance, there are few accidents, and the vehicle itself also has lights, so there is no need to repair the street lights.

As a special road, the highway does not actually need street lights so much, and the installation of street lights makes it unsafe. Because all the people allowed on the highway are motor vehicles, they are equipped with car lights, which are enough to help drivers see the surrounding things clearly, and there are some signs and markings on the highway that will be reflective.

Because it takes a lot of manpower and material resources to install street lights on the highway, and most of the highways are in the wilderness, there are few people, so there is no need to set up street lights, and the lights are easy to cause reflection.

Because the speed of the car on the highway is very fast, if the street lights are installed, it is easier to cause accidents; If you don't install street lights, everyone will be very careful when driving because of the line of sight.

Because the highways are very long, it will cost a lot of money to install street lights, and there are not many cars on the highway at night, which will cause waste.

Mainly because the cost is too high, and the car itself also has lights, and installing street lights will affect the vision of driving.

The expressway is a high-grade highway. According to the Technical Standards for Highway Engineering issued by the Ministry of Communications of the People's Republic of China, expressways refer to "highways that can adapt to the annual average day and night passenger car traffic of more than 25,000 vehicles, and are designed for high-speed driving of cars in separate lanes, and all access is controlled."

<> "Why don't you install street lights on highways?

Cost savings: Highways are usually long-distance, large-scale road systems, and installing street lights requires a lot of capital and human resources, and considering the length and complexity of highways, installing street lights will be an expensive project.

Energy saving: Highways are different from urban roads in that they have a higher density of traffic and higher speeds, in which case it is not necessary to install street lights, as the vehicle's headlights, rear lights, and signs and markings provide sufficient illumination.

Prevent visual interference: Vehicles on the highway usually drive at high speeds, and the light of street lights will produce strong reflection and refraction effects, which will cause visual interference to drivers and reduce the safety of driving.

Highways generally do not have street lights except for important bridge decks and tunnels for the following reasons:

1. The highway line is long, the vehicle flow is too random, and the installation of street lights for the passage of a small number of vehicles is bound to cause a huge waste of energy;

2. The irradiation distance of the street lamp is limited, the general street lamp spacing of the main road of the city is about 30-33 meters, the light pole is the brightest spot, and the center point between the two light poles is the darkest point, if the highway is set up with the street light according to the mode of the urban trunk road, it is assumed that when driving at a speed of 120 kilometers per hour, the distance traveled by the vehicle per second is meters, that is to say, every second to cycle from the brightest spot to the darkest point, the strobe flash line with a frequency of 1hz continues to enter the eye, and it is easy to produce visual fatigue;

Therefore, if street lights are set up on the highway, it is neither energy-saving nor scientific.

Driving on the highway, the lighting mainly depends on the headlights of the vehicle itself, and the lighting of its own headlights is continuous, in addition, the reflective signs installed on the highway guardrail can clearly display the line, enough to complete the function of direction guidance.

A small number of highways will be supplemented by high-pole lights installed at important bridge decks (sea bridges), interchanges or ramps, and speed limits are often used on these sections.

Because the highway section is too long, and the highway section is still closed on both sides of the road without pedestrians, even if you pass quickly on the highway, there will be no traffic accidents, so there is no need to install street lights on the highway.

Why don't you install street lights on the highway, there are no street lights on the highway should be to save electricity, and many places have been limited in the near future. Of course, it may also be that the street lights are being replaced or the new street lights are not installed in time.

First of all, it is mainly cars and not people driving on the highway, so there is no need for street lights. On the other hand, it means that the speed of driving on the highway is fast.

The highway can't be equipped with lights, and the lights are not suitable, and the speed of the highway is too fast.

Let's settle the accounts yourself, one installation cost, one facility cost, one maintenance cost, one electricity cost.

First and foremost, one of the most important reasons is for safety reasons. In fact, there is a big difference between expressways and urban roads, expressways are highways that specifically meet the high-speed driving of automobiles, so the requirements for highway smoothness and construction are more stringent. It is possible for us to have an accident on a city road due to a broken street lamp and a flat tire, but this will never happen at high speeds.

That is to say, although the speed requirements for cars on the highway are relatively high, its safety factor is much greater than that of urban roads, so there is no need to install street lights on the highway, otherwise it will be a bit of a snake.

It is also because of the consideration of the investment in the erection. In fact, many people on the Internet say that it is possible to erect street lights on highways, but this idea is very unrealistic from a practical point of view. According to relevant information, at present, almost all highways in China are funded by the city, that is to say, if you want to erect street lights, you also need to be funded by the city.

At the beginning of the construction of the expressway, the city has invested a lot of money, and the quality of the design has been strictly regulated. Erecting street lights directly on the highway is actually easy to cause fluctuations in the city's economy, and the most important thing is that it is not necessary, so major cities have defaulted to not erecting street lights on the highway.

Finally, there is also the issue of light. When driving on the highway, you need to maintain a high speed, but street lights are scattered light sources, which means that drivers are prone to visual fatigue due to uneven scattered light, which is more likely to induce traffic accidents. Traffic accidents on highways are usually much more severe than those on city roads.

For this reason, there was no choice to install street lights.

There is no street light on the highway This situation is relatively rare, mainly related to the local economic conditions, the economy is backward in many places, and the construction of the highway will require a lot of manpower and financial resources, many areas feel that there are not many vehicles to drive, they are not willing to invest, so it is easy to increase the probability of traffic accidents.

The reason why there are no street lights on the highway.

In many high-speed sections in our country, you will find that there are some street lights that are not installed, which may be related to local economic conditions, and street lights on the highway are very important, and they are also a major factor in safety.

In general, in the construction of highways, a lot of manpower and financial resources are required, if the distance of the highway section is very long, or the difficulty of construction and other factors, this is a huge expense for the local area, and it also requires long-term investment in the later stage, so many areas feel that there are not many vehicles on it.

Therefore, this has created many areas that are reluctant to invest and are unwilling to build high-speed road sections, but most of the highways in our country have street lights, and in the absence of street lights, the visibility on the highway is very low, which will increase the probability of danger, so it should be determined according to different regional conditions.

Because the route of the highway is too long to pull the power stand, and there are fences on both sides of the highway, no one passes with livestock, so there is no need to install street lights.

There are no street lights on the highway, the most important thing is that when we are driving on the highway, the speed is generally relatively fast, and it is easy to shake people's eyes when they hit the street lights, so they are generally not equipped with street lights on the highway.

I don't think it's necessary to install street lights on the highway, because if the street lights are installed, it will affect driving safety, so the highway is not equipped with street lights.

Street lights are convenient for pedestrians, and there are no pedestrian street lights on the highway, isn't it a waste of electricity. I have my own lights when I get on the car at night.

Why don't highways install street lights? The highway should be a high-speed highway, and there is generally nothing on both sides, so people's so there are generally no street lights on the highway.

Other reasons are not to mention that street lights need to be repaired frequently, and maintenance personnel and equipment are unsafe on the road.

There are many reasons why there are no street lights on the highways.

1. Cost reasons.

China's territory is vast, the east, west, north and south span is huge, according to the urban road standard two street lights at a maximum interval of 50 meters, all the installation of street lights, installation and maintenance costs is an astronomical amount.

In addition, the expressway basically passes through the state and the province, and there is no clear demarcation, which will also cause trouble in the management of road sections. In addition, some high-speed sections are scarce with vehicles, and the installation of street lights will also cause a waste of resources.

2. Affect safety.

Street lighting is discontinuous and uneven. For drivers of high-speed vehicles, this alternation of light and dark can cause visual errors (illusions) and can be very dangerous.

At the same time, the lighting of the whole road section will make the driver lose his vigilance subconsciously, which is not conducive to long-term driving. However, some highways are also equipped with street lights, such as tunnels or ramps.

3. Reflective system as a guarantee.

There is a complete reflective sign system on the expressway, including hot-melt reflective markings (lane markings, etc.), film-based reflective contour markings (separation belts, guardrails, etc.), luminous ground nails, etc., which can reflect the traffic lane indication markings, traffic signs, roadside contours, lane dividers and ** divider contours.

So at night, as long as the driver turns on the headlights, these reflective systems can play a role in real-time guidance.

In addition, there is a special reason. In some special areas, based on national defense and military considerations, expressways will be specially designed.

In wartime or emergency times, the first fence and guardrail can be removed, and the highway can be directly turned into a temporary airport for aircraft to take off and land. If there are street lights on these sections, it will also have a certain impact.

Based on the above reasons, there are no street lights on the highway, which is accepted by the vast majority of domestic car owners.

There are no street lights on highways because the cost is too high, affecting driving safety, and so on. Due to the vast territory of our country, according to the urban road standard, the maximum interval between two street lights is 50 meters, and the cost of installation and maintenance is very high if street lights are installed on the highway.
