Explanation:

Definition of a Reverse Curve:
A reverse curve consists of two arcs of equal or different radii bending in the opposite direction. This means that after a vehicle negotiates the first curve, it must immediately negotiate a second curve in the opposite direction.

Characteristics of a Reverse Curve:
- Reverse curves are designed to gradually change the direction of the road alignment, allowing drivers to safely navigate the change in direction.
- The radius of the second curve is often larger than that of the first curve to ensure smooth transition between the two curves.
- Reverse curves are typically used in highway design to accommodate changes in terrain or to maintain a consistent alignment with existing roadways.

Importance of Reverse Curves:
- Proper design of reverse curves is crucial for ensuring driver safety and maintaining traffic flow.
- By providing a smooth transition between curves, reverse curves help prevent accidents such as skidding or rollovers.
- Well-designed reverse curves also improve the overall driving experience by reducing the need for sudden changes in direction.

Conclusion:
In conclusion, a reverse curve consists of two arcs of equal or different radii bending in the opposite direction. Understanding the characteristics and importance of reverse curves is essential for civil engineers involved in highway design and road safety.

Concepts:
Reverse Curve: 
  • When two simple circular curves of equal or different radius bending or curve in opposite directions with a common tangent at their junction, their centers being on opposite sides of the curve. 
Characteristics of Reverse Curve:
  • They are also called S curves as they appear like the English letter ‘S’.
  • They are provided between two parallel lines or the angle between them is very small.
  • They are suitable for railway yards but not suitable for highways.
  • No superelevation is required.
  • Wherever reverse curves are necessary to use, long lengths of straight portion (minimum 36 m length) should be provided in between two reverse curves.
