What is the purpose of the floodlights on the highway?

[Elliana]

The functions of floodlights on highways are: highlighting red lights, alerting drivers, preventing driver fatigue, capturing speeding, recording illegal use of emergency lanes, monitoring accident-prone areas, detecting various violations near ramps, and traffic flow monitoring. Here is relevant information about highways: 1. Definition: Highways belong to high-grade roads, which are designed to accommodate an average annual daily traffic volume of over 25,000 small passenger vehicles, exclusively for high-speed divided-lane automobile traffic with full access control. 2. Classification: Highways are divided into five grades: expressways, first-class roads, second-class roads, third-class roads, and fourth-class roads. Expressways can also be categorized into urban expressways and intercity expressways.

As someone who frequently drives on highways at night, I deeply appreciate those overhead high-mast lights as literal lifesavers. They function like beacons illuminating the darkness, providing uniform and bright lighting that makes distant road conditions clearly visible. With numerous curves and heavy traffic flow on highways, these lights effectively reduce blind spots, preventing drivers from dozing off due to poor visibility or missing exits. Particularly during rainy or foggy seasons, their strong light penetration helps detect potholes or obstacles in advance. From a safe-driving perspective, these facilities aren't just decorative—they represent mandatory safety standards maintained by government investment to safeguard public security. Without them, accident rates would undoubtedly surge. I believe that well-planned light pole arrangements can also guide drivers to maintain proper lane discipline, preventing dangerous lane changes.

I have some knowledge about highway facilities. The high-power LED floodlights on highways are mainly installed on pillars to cover the entire road section. Their design aims to maximize light uniformity and reduce glare interference for drivers. The voltage system combines grid power and backup power to ensure stability. Their function goes far beyond illumination; they can also indirectly control traffic flow by adjusting brightness to indicate cautious speeds in different sections. For example, at tunnel entrances or construction zones, strong flashing lights remind drivers to slow down. This intelligent setup is more efficient than mere road signs. In terms of maintenance, regular lens cleaning and replacing aged bulbs are key. After multiple community feedbacks, efficiency has significantly improved nighttime driving quality.

Last family trip, we relied entirely on these lights to smoothly navigate the highway at night. They illuminated the road ahead, reducing driving fatigue. Simply put, they turned darkness into safety, preventing misjudgment of distances. Most modern lights are energy-efficient and eco-friendly, saving significant electricity costs in the long run.
