Upward Left Curve

Many parameters are needed to specify the curve. They are shown below.
\item {\em Direction} --- left
\item {\em M...
...t Clothoid Angle} --- $45$ \item {\em Height} --- $50$\end{itemize}\end{spacing}
A fairly large radius of curvature is chosen, since the anticipated speed at the bottom of the curve (the beginning of the element) is large. Another way to deal with a high speed at the beginning is to use a larger entrance clothoid angle to allow the car to slow down some, by rising to a higher elevation, before the highest curvature region is encountered.
