The radial metric
is defined on
lie on the same line through the origin, and
otherwise. It looks like a centralized train network, and has been called the French railroad metric.
A neighborhood of a point
, is either a line segment through
on the ray from the origin through
or the union of a segment from the origin through
and a disk centered at the origin.
