There are some helpful Intersection and Junction Tools available for Road Design.
Used for rapid design and drawing of complete intersection, based on the input of parameters or designed gradually by means of the individual programs. This lends great flexibility to the system since the user has the option to evaluate alternative intersections in a relatively short period, with the map/design as a background. The user can switch from the right lane to the left lane by typing lane setup in the CAD command line.
