Roads that are divided into two parts are known as divided roads. These roads have a physical barrier separating the lanes of traffic moving in opposite directions. Divided roads are designed to improve safety and traffic flow by reducing the risk of head-on collisions and allowing for smoother traffic movement.

Types of Divided Roads
- Median-divided roads: These roads have a raised or depressed barrier running down the center, separating the lanes of traffic. The barrier can be made of concrete, metal, or vegetation.
- Grass or landscaped median: Some divided roads have a grass or landscaped area in the center instead of a physical barrier. This type of median also helps in reducing head-on collisions.
- Cable barrier: In some cases, a divided road may have a cable barrier in the center to prevent vehicles from crossing over into oncoming traffic.

Benefits of Divided Roads
- Improved safety: Divided roads reduce the risk of head-on collisions, which are often more severe and result in higher fatality rates.
- Increased traffic flow: Divided roads allow for smoother traffic movement, reducing congestion and improving overall traffic flow.
- Better visibility: Divided roads provide better visibility for drivers, especially at night or in adverse weather conditions.
- Enhanced aesthetics: Landscaped medians or barriers can enhance the visual appeal of the road and surrounding areas.

Conclusion
Divided roads play a crucial role in ensuring road safety and traffic efficiency. By separating lanes of traffic, these roads help in reducing accidents and improving the overall driving experience for motorists.
