Why not install streetlights on highways but install reflective road stud ?

Why are there no street lights on the highway? Can drivers drive safely on highways without street lights at night? If you are also passing high speed at night, I am sure you will find that there are no street lights on most highways. Why is that? Today, Lucy simply talks to you about why not install street lights on the highway.

The role of streetlights is more designed for non-motorized vehicles and pedestrians who do not have the ability to illuminate roads at night to ensure that they can travel safely and conveniently. However, on the expressway, pedestrians and non-motor vehicles are generally not allowed to walk on the highway, and the expressway is a closed road,so there will be no road conditions like the mixed traffic between people and vehicles on the city road. All in all, the road conditions of expressways are relatively simple. For drivers, as long as you pay attention to the road ahead and maintain a good distance, there will be no major problems.

1.  Security issue . A driver who often runs the night road said that running the road in the city, because there are street lights along the way, driving a few dozen kilometers will be paralyzed. It is very easy to get sleepy. In fact, the street lights are usually separated by a distance. The alternating light and dark lights will give the driver a visual illusion. The street lights are scattered and the illumination is not very good. When you are in this kind of light for a long time, you will experience visual fatigue

2. The expressway has a contour mark every 25 meters on both sides of the guardrail . There are high reflective effect markings and reflective spikes on the road surface .As long as the headlights are turned on at night , the highway reflection effect is very good. Lights on the road can affect the effect of high-reflection markings and reflective spikes.

3. Highways are usually driven by high-beam lights. In this case, the effect of the lights is greatly reduced. The speed on the expressway is relatively high. Some signs use reflective technology. When the lights are taken up, the driver can be obviously reminded, and the lights on the side of the road will interfere.

4. Cost issue. The distance between the expressways is very long. If the roads are installed, the street lights and electricity bills are not small expenses. In addition, a highway may span several provinces and cities, so that the power supply and management of each section is relatively troublesome .   

In summary, it is impossible to install street lights on the highway. The headlights on our cars are enough to provide illumination for the road ahead. Simply installing reflective road studs on the road can be a good guide.
