Problem Statement

A road has constant width. It is made up of finitely many straight segments joined by corners, where the inner corner is a point and the outer side is a circular arc. The direction of the straight sections is always between NENE (45o45^o) and SSESSE (1571/2o157 1/2^o). A person wishes to walk along the side of the road from point AA to point BB on the same side. He may only cross the street perpendicularly. What is the shortest route?
