Which equation discusses horizontal sight distance in relation to stopping sight distance on horizontal curves?

• A. Eq. 3-36
• B. Eq. 3-37
• C. Eq. 3-38
• D. Eq. 3-39

Answer: (B)

The equation that discusses horizontal sight distance in relation to stopping sight distance on horizontal curves is indeed focused on ensuring that drivers have adequate visibility to safely navigate curves. This is critical in transportation engineering, as limited visibility can lead to increased stopping distances and potential accidents. Specifically, the equation typically known in transportation design literature captures the relationship between the curve's radius, the driver's eye height, and the height of an object on the roadway. It takes into account the necessary sight distance required for a driver to perceive and react to an obstacle, allowing for safe stopping. In the context of horizontal curves, understanding and utilizing the correct equation helps engineers design roads that maintain safety and efficiency, ensuring that vehicles can travel through curves without encountering visibility issues that could lead to collisions or loss of control. This emphasizes the importance of balancing design speed with adequate stopping sight distance, crucial for effective roadway design and traffic safety.
