Madam, - Before Frank McDonald's mouth-watering transport visions for Dublin come into being, there's a useful, cheap and simple action that would make life easier for travellers. This is to produce an overall transport map, showing all the existing bus, coach, rail, Dart and Luas routes in the area. Is there any hope that a Dublin Transport Authority will be formed to do such a radical thing? - Yours, etc,
DAVID SOWBY,
Knocksinna Crescent,
