Patent ID: 8650004

Claim:
A method for generating a representation of a roundabout for display via a computer, the method comprising: receiving, via an electronic device, an operator selection of a design vehicle that is expected to use the roundabout; receiving operator input of a design dimension for the roundabout, said roundabout including a central island surrounded by a circulatory lane, said design dimension defining a size of one of: the central island; and an outer perimeter of the circulatory lane; generating a circulatory path of said design vehicle traveling within said design dimension along said circulatory lane, said generating of the circulatory path based on said selected design vehicle and said design dimension; generating vehicle extent locations based on said selected design vehicle and said generated circulatory path, the vehicle extent locations indicating passage of said design vehicle along said circulatory path; generating a circulatory lane width based on said generated vehicle extent locations; and generating the representation of the roundabout based on said generated circulatory lane width and said received design dimension.
