|Abstract:||This paper investigates the nature of tours undertaken by public transport and car. Using a new approach to the typology of tours, which takes into account not only the number but also the spatial distribution of activities chained into a tour, the paper sheds light on the reasons why conflicting findings exist in the research literature. Descriptive and modelling analyses on a home-based tour dataset created from the Sydney household travel survey show that tours using car or public transport are different in nature. For public transport, activities chained into a tour have destinations which are typically in close proximity and reachable by walking whereas the car was found to be utilised for travel involving multiple purposes at multiple destinations. The new approach to the typology of tours proposed in this paper which takes the destination into account gives clearer and more significant relationships between tour complexity and mode choice, allowing potential policy and planning implications for promoting public transport ridership to be drawn. The results indicate that the spatial dispersion of activities chained into a tour significantly reduces public transport use for all travel purposes. Conversely, public transport use increases as the number of activities sharing a destination with others chained into a tour increases. These findings suggest that planning strategies to increase public transport use need to focus on providing multiple purposes at a single destination.|
