What is the street lighting standard?
In this article, we are with you by addressing the street lighting standard, the latest changes in these standards and the introduction of the street light base. Every day, millions of people travel in cities and use urban roads. The presence of street lighting is one of the necessities of urban life. For this reason, it is necessary to follow the standards related to the lighting of the roads so that the traffic of pedestrians can be carried out without the slightest risk.
If the roads are not lit enough, the passers-by will not have a good view, on the other hand, too much light can reduce the visibility and distract the drivers. For this reason, it is necessary to follow the street lighting standard. Depending on which parts of the lighting should be provided, the standard of street lighting will be different.

The importance of street lighting
In the road lighting standard, it is necessary to state the Ministry’s definition of roads. All main roads, sidewalks, highways, highways, bridges, streets and alleys are classified as roads. So all these things should have good lighting and in accordance with the standards of the day. The process of urban life slows down during the night, but it will not stop. The darkness of the night can cause unfortunate incidents, including traffic accidents. Street lighting and outdoor lighting play a huge role in reducing the number of traffic accidents.
On the other hand, the darkness of the night is a good platform for criminals in the Golan, but despite the sufficient lighting of the roads and the presence of CCTV cameras, we can hope to reduce the number of violations during the night. The lighting of the roads makes it possible for the military and security forces to better monitor the traffic.
The lighting of the roads provides the possibility of safe and smooth traffic for people during the night. Also, people will be able to continue their economic and commercial activities. The importance of street lighting becomes more clear in the second half of the year when the days are shorter. The lighting of the roads gives a dynamic and lively state to the city and will provide the opportunity for the citizens to have fun. Big and industrial cities are lit all night and this means the continuation of industrial activities at night despite the lighting of the roads.
Remarkable points in the street lighting standard
One of the most important points in the road lighting standard is uniformity of lighting. The environment should be uniformly lit so that the attention of drivers and passers-by is not drawn to a specific element in the environment and does not cause glare. Glare is one of the components that must be observed in a standard crossing. Brightness and background lighting are also of special importance in roads. There are different categories in the road lighting standard. One of the most important categories is the role of the passage in daily activities.
Geometric characteristics and the amount of traffic (coming and going) in the passage also play a role in determining the standards. Highways and freeways are first-class arterial passages, and main and secondary roads are also classified as second-class arterial passages. Sidewalks and local accesses are among the important subsets of roads. Each of the mentioned items has its own standard. In the standard of road lighting, the average height of human vision is considered to be 170 cm.

Determining the appropriate height in the street lighting standard is very important. The lighting height should be such that it does not cause glare, that is, it does not focus the viewer’s attention on a specific point. On the other hand, if the lighting is too high, its effect will be reduced and the intensity of the light will not be enough.
Light intensity measure
Light intensity is measured by Lux standard. Each passage requires different lighting intensity depending on its type. The brightness varies from 7 to 16 lux. The type of asphalt, whether it is commercial or residential, the type of area is also effective in determining the intensity of lighting. Residential areas should have less light because they are residential areas, while commercial areas require more light intensity.
Another important point in the street lighting standard is choosing the right lamp. The size of the lamp should be appropriate. in such a way that, while maintaining the brightness, it does not cause the facade and the beauty of the passages to be lost. The color of the lamps should also be chosen carefully. White and yellow are among the colors that are used in street lighting. Due to their proximity to the color of the day, these colors have a suitable light spectrum to be used in streets. Other colors may cause eye irritation. The power supply of roads is the responsibility of the Ministry of Energy. But ensuring the health and efficiency of street lighting is the responsibility of the municipality of each department. Also, the standards of road lighting in our country have been determined by the Ministry of Energy.

Lights used in street lighting
The lights used must have a standard distance from each other. This distance will be different depending on the type of place. But generally, intercity lights are 25 to 30 meters apart. Of course, keep in mind that the distance between the lights on the sidewalk and places like parks and gardens can be less. This distance is from 35 to 40 meters on roads, freeways and highways. Obviously, the light intensity should be higher in these areas. The projectors used should have a power equivalent to 150 to 250 watts. Solar projectors are another type of lights that are used for this purpose. The lights used should be anti-fog and not create shadows in any way.
The lights should be slanted so that the light shines at a better angle. Street light bases are generally installed in four ways: zigzag, opposite, one-way and two-way. Depending on the geographical area, whether the road is single-lane or two-lane, the width of the road, the maximum number of lamps and the allocated budget, the mode of installing the lights will be different.
In the standard of road lighting, all the groups that use that road should be taken into consideration. For example, the standard of lighting in roads where only cars pass is different from roads where cars and people pass by.
