Read the following abstract, objective and some information about the methods in getting the data

ABSTRACT With the onset of COVID-19 restrictions and the slow relaxing of many restrictions, it is imperative that we understand what this means for the performance of the transport network. In going from almost no commuting, except for essential workers, to a slow increase in travel activity with working from home (WFH) continuing to be both popular and preferred, this paper draws on two surveys, one in late March at the height of restrictions and one in late May as restrictions are starting to be partially relaxed, to develop models for WFH and weekly one-way commuting travel by car and public transport. We compare the findings as one way to inform us of the extent to which a sample of Australian residents have responded through changes in WFH and commuting. While it is early days to claim any sense of a new stable pattern of commuting activity, this paper sets the context for ongoing monitoring of adjustments in travel activity and WFH, which can inform changes required in the revision of strategic metropolitan transport models as well as more general perspectives on future transport and land use policy and planning.

The objective of this paper is to provide a framework via which the increased working from home observed during COVID-19 can be introduced to such strategic models, to guide policy makers on appropriate decisions during the life of the pandemic and also to help forecast a future with increased working from home to guide important transport investment decisions, and updated easily as new data on working and commuting is collected.

Sample and survey This paper presents analysis on working from home and commuting data collected in two waves of study, Wave 1 (30th of March to the 15th of April; for the purposes of this paper modelling is conducted on 476 observations who work) and Wave 2 (23rd of May to 15th of June; analysis is conducted on 705 observations who travel for work). Table 1 provides an overview of the sample demographics for each of the two waves of data collection thus far. Note that numbers may vary in the margins from wave to wave, as the priority is on recruiting as many recompletes as possible in order to build a panel, and thus an ability to eventually investigate panel effects within respondents. That being said, both samples compare favourably to the general characteristics of the Australia population as per Australian Bureau of Statistics (ABS) census data.
