Typography used for Turkish Road/Highway signs

I am searching for the specifications on the Typography used for the TURKISH ROAD / HIGHWAY SIGNS
As far as I have been able to track, the name is: CARRETERA, and exists in two series an E and an O.

Can somebody confirm this?
And does anybody know of further specifications and eventually on how to buy it/ come across it?
Who has drawn it?

Thank you



See for example post 4 and 6.
