What does the term "crown" refer to in the context of road design?

In the context of road design, the term "crown" refers to the highest point of the road. This design feature is crucial for proper drainage and water management. By having the road rise in the center, water is encouraged to flow away from the road surface towards the edges, reducing the chances of water pooling on the roadway and minimizing the risk of erosion or structural damage to the pavement.

Additionally, a crowned road enhances safety by improving visibility for drivers and ensuring that the roadway remains more stable during adverse weather conditions. Understanding this aspect of road design is essential for emergency response drivers, as it helps them navigate safely in varying weather and road conditions.
