Highway Road Design- Horizontal Curve Design

I have done more than 500 km of road design. This included variety of road from Hilly Terrain to Plain Terrain, Rural Road and Urban Road. Based on survey data received as X-Y-Z, points are imported and plotted in to CAD software. The Contour os elevation in desired area of interest is generated and an existing road centre line is traced. The Horizontal Alignment is then designed based on specified road standard and design speed of the country/state. The Horizontal Alignment gives super elevation and extra widening at curves. Please se a sample Horizontal Alignment Design of a project completed recently.
