Design the horizontal alignment to connect two parallel streets with a reverse curve. The horizontal transition length $($d$)$ is $175$ feet, while the offset $(h_1)$ between the two streets is $65$ feet and the deflection angle is $48.$ The design speed needs to be $30mph,$ and the superelevation rate $2\%.$ Determine the minimum radius, tangent and length of the two curves, and the stations for all of the horizontal points of curvature. Begin at STA $10+00$ at the first point of curvature $($PC$1)$
