Musical road sign in Japan by Tzuhsun Hsu

In this (as always) great article from 99% Invisible, they talk about the Melody Roads, an interesting idea to make cars produce a melody when driving over a road at the correct speed. The technique, that requires a lot of precision, has been used in several countries to make drivers reduce the speed in order to listen to the melody correctly or just as a tourist attraction.

Here some more signs of Melody Roads from Okaniwa, Japan and New Mexico, USA.
