Other previous maps have been commissioned to an external agency (
Pindar), and there are similarities in this one to those maps.
Either way, internal or externally done, if they've gone to the trouble of commissioning guidelines, they should be adherent to them, particularly on occasions when they are in direct control of the information/maps. If the NTA itself isn't bothering to try and follow it's own guidelines, how can it corral the transport providers to do so?
