I think it’s one of the most unattractive and horribly designed transit maps out there. It hasn’t been redesigned or reworked for a large number of years. Its choice in colours is uninspiring and doesn’t really offer much to people using it.

Transit Maps says:

While certainly not the worst transit map out there by any stretch of the imagination, this map is so bland and generic that it looks like it escaped from the cookie-cutter factory. There’s no major technical defects or horrible mistakes, but it’s just so… meh.

Aesthetically, things could be easily improved by rounding the corners where routes change direction and adopting a more contemporary colour palette (that yellow fare zone is pretty hard on the eyes). The part that needs the most work is definitely the table of station details underneath the actual map, which is pretty terrible. The table alone takes this down from a completely average (meh) score of 2.5 stars to a lowly two.
