Understanding the influence of availability measures on bus ridership: Brisbane case study

Human travel behaviour pertaining to public transit uses relies on various external and internal factors. This study focus on one of the internal factors, which is Transit Quality of Service (TQoS). This analysis primarily concentrated on service availability measures of TQoS, which is the prerequisite for transit service usage. This paper aims to identify the most influential availability measure that govern ridership variation between areas. It examined a number of possible variables through regression models in order to establish the best estimator variable regarding service availability. Apart from the existing service availability measures prescribed by the Transit Quality of Service Manual (TQSM), this study developed a new approach of analysis by synthesising typical availability measures into several single variables. Amongst them, the service intensity (SI) (bus-km/km2), which is a systematic combination of service frequency (SF), service span (SS) and route density (RD), had the best capability of explaining spatial variability in ridership rate between areas. The study concludes that bus service intensity is a key driver of service availability indicator. Hence, before investing valuable resources, transit agencies can utilise this measure to understand how it will influence the overall bus transit availability of an area and verify the plausible benefit from the investment.
