The sample, 840 observations, is choice based with over-sampling of the less popular modes (plane, train and bus) and under-sampling of the more popular mode, car. The level of service data was derived from highway and transport networks in Sydney, Melbourne, non-metropolitan N.S.W. and Victoria, including the Australian Capital Territory.a:: Number of observations: 840 Observations On 4 Modes for 210 Individuals.
