Horizontal Alignment An existing road with a design speed of 85 km/h passes from one tangent through a right-hand circular arc onto a second tangent, and then through a left-hand circular arc onto a third tangent which is parallel to the first. The circular arcs are joined to the straights by clothoid transition curves. Radius of both circular arcs 775m Rate of gain of radial acceleration on all transitions Length of straight between the two curves Length of both circular arcs 0.43 775m 250 m a) What is the perpendicular distance between the parallel straight sections? b) Using the same tangents and Intersection Points, the arc radii are increased to 2500m
