Answer 1

The factor that is required in long stretches of the road and even more on complicated intersections is Visual guidance.

Visual guidance

The visual system converts light entering the eye into electrical signals that travel along the optic nerve to the brain.
In the brain, those electrical signals are processed and result in the images we call sight. Therefore, light is most critical in our ability to see. Without sufficient light, there is no contrast between the object and the background, so vision is poor at night.
Visual guidance is crucial for ensuring that drivers can navigate the road safely, especially at night or in poor visibility conditions.
It includes the use of lighting, road markings, and signs to help guide drivers through complex road layouts and intersections.
While the limitation of glare, level of luminance, and width of illumination are also important considerations in road lighting design, visual guidance directly addresses the need for safe and clear navigation in these challenging areas.
