Most drivers have traveled on highways, and during the day, there may not be any noticeable issues. However, at night, it becomes apparent that without headlights, the road is pitch black with no streetlights installed on either side.
The reason for this is that even though high beams can meet the basic safety driving conditions, drivers may still experience fatigue due to heightened concentration, and prolonged viewing can lead to dizziness.
Since highway driving conditions are not ideal, it is possible to install solar streetlights for illumination. However, many highways in the country do not have solar streetlights. Could it be that solar streetlights might affect safe driving? According to research, the absence of solar streetlights on highways is primarily due to the following reasons:
1. High safety factors on highways
Highways are elevated roads connecting cities with cities and urban areas with rural areas, with very few non-motorized vehicles and pedestrians. Thus, generally, highways do not have solar streetlights. Moreover, highway surfaces are usually very flat, without significant potholes or irregularities, maintaining good road conditions and higher safety levels.
2. Reflective signs on the road can meet requirements
Generally speaking, the illumination from solar streetlights is intermittent and uneven. For high-speed vehicles, this alternating brightness can cause visual illusions, which are very dangerous and can quickly lead to eye fatigue. Furthermore, the illumination level of typical solar streetlights is poor, and the scattered light can produce glare for drivers on long journeys, posing safety risks. Also, when external lighting is insufficient, vehicle headlights provide safer illumination (high beams can reach about 100-150 meters).
3. High costs
This reason is quite understandable; for example, the distance between any two cities on a highway is approximately 200-600 kilometers. If solar streetlights were installed across such long distances, the costs would be significant.
4. Currently, most highways do not have solar streetlights
However, during nighttime driving, well-maintained road signs and reflective markers can fully meet the requirements. Under the intense light of headlights, the reflective film on traffic signs and road markings directs the light to illuminate the road and clearly reflect various traffic signs to the driver’s eyes, sufficiently guiding direction.
Therefore, based on the above four points, one can conclude that as long as road signs are complete and the reflective surfaces are intact, safe nighttime driving can be guaranteed on highways! Conversely, having solar streetlights on highways may not necessarily be a good thing; they could become “deadly weapons.” If lighting conditions are too good, it may cause drivers to let their guard down. The highways are significantly different from ordinary roads, and once an accident occurs, there is a higher probability of subsequent crashes. Hence, it is recommended for drivers feeling fatigued at night to stop at rest areas to recuperate. This is one of the reasons for not installing solar streetlights.
