Investigating the Ipswich to Brisbane commuting pattern: a quantitative approach (journal article)

"Through a quantitative analysis of JTW data available in the Census of Population and Households we add to the current planning debate on traffic congestion in the Ipswich·Brisbane corridor. The analysis of JTW data enables investigation of the notion that there are high levels of leakage of Ipswich's residents commuting from Ipswich to the neighbouring Brisbane Local Government Area (LGA). In doing so we use quantitative methods to firstly calculate the degree of self containment (i.e. the proportion of people living and working within an area) within the Ipswich sub-region and secondly to map the mean direction of commuting. More specifically, the policy problem addressed in this paper is to determine the extent to which commuters living in Ipswich have a tendency for an easterly direction of JTW travel (i.e. towards Brisbane City and Brisbane's CBD using the main east-west corridor). We suggest
that the visual exploration of the JTW data can enhance the analytical capability through the integration of statistical and cartographic measures to assist in transport planning."
