The Me and The Roads Model
It would be nice not to have to care about matr's representation of the road system, but the grid model it uses will affect your work in several ways.
Lingwoo is divided into a grid of 0.2-mile squares. Each square is either underwater or part of a town. Land squares may also contain one intersection (see below).
Roads can enter a square in any of eight directions (at 45 degree angles), but some simplifying assumptions restrict the types of intersections you can create (see figure). Each segment of road can have up to two route numbers and one street name associated with it (or nothing at all).
Above are all valid and some invalid intersection types in Me and The Roads. Any reflection (flip) or rotation of the valid ones is also valid. In general, you can't have five-way intersections, bend in the middle of a four-way, or meet on the inside "elbow" of a sharp curve.
