Sustainability of voluntary travel behaviour change initiatives: A 5-year study

During the early part of the first decade of the 2000s, a number of localities in Australia introduced Voluntary Travel Behaviour Change (VTBC) initiatives, otherwise known as TravelSmart. These initiatives were all monitored in the short-term and suggested that there were reductions in person kilometres of travel (PKT) on the order of 6 to 18 percent. Beginning in 2007, the Institute of Transport and Logistics Studies (ITLS) was asked to undertake a 5-year study to determine if the effects of TravelSmart were sustained in the longer term. This paper describes the study methodology, which was a rotating panel drawn from the Australian Capital Territory, Queensland, South Australia, and Victoria, with panel members asked to carry a GPS device with them wherever they went for a period of 15 days in September-November each year from 2007 to 2012: six waves of panel data. All members of sampled households over the age of 14 were provided with a GPS device to carry with them. The paper reports on panel attrition and the make up for attrition. The panel covered 120 households per year, with approximately 40 households that had not participated in TravelSmart (the control group) and 80 households that had participated, with make up for attrition maintaining this split. Details of the sampling procedures are provided in the paper. The sample provided data on about 3,600 person days of travel in each wave or a total of about 20,000 person days of travel over the six waves. The paper reports on the year-by-year averages of PKT for each of the two groups and for each state and overall. It was found that, while there was some variation from year to year, in general, the treatment group continued to show lower PKT than the control group, suggesting that the changes were sustained over the study period. This is the first time that a longer-term monitoring of the effects of a VTBC has been undertaken, and is also the first one to use GPS measurements of travel to do this

Not too late to learn from the Sydney Olympics experience: Opportunities offered by multimodality in current transport policy

Sydney is the Australian city that attracts the most global attention with its beautiful harbour, its iconic attractions of the harbour bridge and opera house. Tourists may leave Sydney with a complimentary view of Sydney’s public transport but the Sydneysider’s assessments of Sydney’s public transport system is often much harsher, especially if the journey requires travel beyond the immediate centre of the city. In Sydney, the reference point of what constitutes a functioning transport system is informed by the success of the transport system in meeting the needs of the participants and observers at the Summer Olympics of 2000. Changes to the transport system to provide more multimodal travel were supported by Sydneysiders and visitors and this paper analyses why this success has not been translated into everyday public transport. The paper identifies opportunities which still exist for Sydney to benefit from the success of these Olympics. These opportunities involve strengthening the opportunities for, and acceptance of, multimodal trips by the travelling public
