Dual Carriageway 

Dual carriageways can have very complex geometry with different horizontal and

vertical alignments for each carriageway. This introduces various width and height

differences at the median. Devotech iDAS has a tool to link profiles dynamically to

corridors which allows it to link the median geometry to carriageways so that the

entire corridor updates automatically. Other tools allow the user to link drainage

and guardrail details in the profile views (longsections) dynamically to the corridor.

Devotech iDAS also provides various subassemblies which can be used for the

dual carriageways:
