This thesis, by Helen Abrahams, examines whether Brisbane's Goodwill Bridge induced walking and cycling traffic. It was published in 2002.
Use of the Goodwill Bridge is restricted to walkers and cyclists and so it provides the opportunity to ascertain if a high quality transport facility will entice people out of their cars during peak hour.
Ten percent of 397 bridge users surveyed had switched to cycling or walking for their entire trip to work. Twenty-six percent of commuters were cycling or walking for all or part of their trip and a total of 39% had changed their trip to include a walking or cycling component. These findings indicate induced traffic does result in a positive outcome with the provision of improvements in a cycle network which also allows pedestrian access.
The study recommends implementing travel demand management programs to further increase the level of induced traffic. A number of large trip generators adjacent to the Goodwill Bridge location provide the opportunity for workplace travel behaviour change programs.
