CAD FOR ROAD AND RAILWAY DESIGN	09/10/2009
	Modern road and railway design depends largely on software developed by specialist companies. Grontmij | Carl Bro as selected the InRoads, InRail and MXRoads package by Bentley as a basis for Computer-Aided Design of roads and railways. InRoads and MXRoad is used for terrain modelling, alignment and typical cross sections as well as for modelling superelevations and drainage conditions, etc. for road and rail projects while InRail is used for the statistical processing of track measurements and alignment design. Grontmij | Carl Bro develops own Supplementary Tools Grontmij | Carl Bro's design experts have developed their own supplementary software to these packages. The design tools comprise automated intersection and interchange design, slope patterning, a GIS-based system for land acquisition and surveying and tools to improve the efficiency and quality of daily design procedures and project documentation. The visualisation tools comprise photomontage and prospective modelling.
