Mae'r Papur Gwyn yn mynd ati hefyd i amlinellu cynigion ar gyfer gwella gwaith partneriaeth rhwng yr awdurdodau lleol drwy sefydlu Cyd-awdurdodau Trafnidiaeth, a fyddai'n ymdrin â gwasanaethau bysiau ac â thrwyddedu tacsis a cherbydau hurio preifat.
The White Paper also outlines proposals for improved partnership working between local authorities through the establishment of Joint Transport Authorities, which would relate to both bus services and the licensing of taxis and PHVs.
