Two straight sections of road are to be linked by a wholly transitional curve comprising two clothoid spiral curves with differing rates of gain of radial acceleration. Deflection angle between the two straight sections of road 40 Rate of gain of radial acceleration for entry transition curve Rate of gain of radial acceleration for exit transition curve 0.32 0.32 m/s3 0.48 0.48 M/5³ 3 Answers required: a) What is the value of the point radius where the two transition curves meet? b) What is the distance between the horizontal intersection point where the two straight sections of road intersect, and the centre of the circle of which the point radius mentioned in part (a) above is a part?
