Public Transport Alliance was formed during the development and adoption of the Integrated Regional Transport Plan for Southeast Queensland when it became increasingly clear that, while many of the specific interest groups based on membership interests were actively seeking improvements for their membership, there was no group which could address the "integration" of these interests. PTA is therefore "interest based" not membership based. It relies on information and assistance sought and provided by the range of interests active in seeking improved alternatives to reliance on cars as a mode of transport. PTA has been involved in projects ranging from the implementation of the "model" bus-rail service to Ipswich UQ campus to the Goodwill Bridge. PTA is currently seeking a similar bus-rail service between Brisbane and Toowoomba using fully accessible buses with US style front-mounted bike racks.
