A bimodal accessibility analysis of Australia’s statistical areas

Abstract

The map presented in this paper summarises the combined land-and airside accessibility within Australia. To this end, we calculate a bimodal accessibility index at the scale of statistical units by aggregating the (shortest) travel time for three route segments: (1) road travel from the origin to a departure airport, (2) air travel, and (3) road travel from an arrival airport to the destination. The average travel time from a statistical unit to all other statistical units is calculated for the units' population centroids, after which an accessibility surface is interpolated using kriging. The map shows that southeastern Australia is generally characterised by a high accessibility index with the most populated cities being hotspots of accessibility. Central and northern Australia arewith few exceptionsfar less accessible. In addition to this largely-expected pattern, the map also reveals a number of specific and perhaps more surprising geographical patterns.

“…It can be divided into two categories: the ease of transportation availability, measured in terms of temporal or spatial distance, and the magnitude of opportunities for interaction, measured in terms of out-ofdistance or weights between two nodes [5]. Airport accessibility is mainly categorized into ground transportation accessibility [6] and route network accessibility [7]. The former is mainly measured by the benefit-cost ratio index [8], cost function [9], gravity model [10], graph theory [11], mixed nested logit model [12], and other models that can be used to analyse an airport's industrial radiation to the local area.…”

“…Section 2 presents a literature review dealing, in turn, with the concept of (bimodal) accessibility and approaches for collecting web-based travel data. In section 3, we elaborate our analytical strategy, briefly introduced in Meire, Derudder, and Ooms (2019). The first subsection provides a description of our Australian study area, including a discussion of the selection and configuration of origins, destinations and airports.…”
