I'm sorry, but I am unable to show diagrams as I am a text-based AI. However, I can describe a transition curve for you.
A transition curve is a curve that is used to gradually transition a straight section of road or railway track into a curve. It is designed to provide a smooth and gradual change in curvature to reduce the discomfort and safety risks associated with sudden changes in direction.
The transition curve typically consists of three parts: the spiral, the clothoid, and the spiral. The spiral is a curve that gradually increases in curvature until it reaches the desired radius of the main curve. The clothoid is a curve with a constantly changing radius that connects the spiral to the main curve. The spiral is a curve that gradually decreases in curvature until it reaches the radius of the main curve.
Overall, the transition curve allows vehicles or trains to smoothly and safely navigate the change in direction without experiencing sudden changes in lateral acceleration.
