Are There Street Lights on Highways?
1 Answers
There are no street lights on highways. Installing street lights on highways is costly and affects driving safety. Highways have a comprehensive reflective system to ensure driving safety. Below is a detailed explanation of why highways do not have street lights: Cost Reasons: China has a vast territory with significant spans from east to west and north to south. According to urban road standards, the maximum interval between two street lights is 50 meters. Installing street lights across the entire highway network would result in astronomical installation and maintenance costs. Safety Concerns: Street light illumination is discontinuous and uneven. For drivers of high-speed vehicles, this alternating light and dark can cause visual errors (illusions), which are very dangerous. Reflective System as a Solution: Highways are equipped with a comprehensive reflective marking system, including hot-melt reflective markings (such as lane lines), film-type reflective delineators (for barriers and guardrails), and illuminated ground lights. These can reflect road indicators, traffic signs, roadside outlines, lane dividers, and central median outlines.
