Why is using a subway considered one of the safest ways of crossing a road?

Using a subway is considered one of the safest ways to cross a road because it eliminates the risk of vehicle collisions by allowing pedestrians to travel underground, away from traffic. Subways are designed to provide a dedicated passage for foot traffic, reducing the chance of accidents caused by distracted or speeding drivers. Additionally, subways often feature well-lit, monitored environments that enhance safety and security for users. Overall, they provide a controlled and protected means of crossing busy roadways.
