The changing role of women in recent decades explains much of the growth in hours travelled. Accurate valuation of the travel time of busy women is required to optimise investment decisions about transport infrastructure. If policy makers, planners and private sector providers use inaccurate estimates of the shadow price of the travel time of women, they will make incorrect investment decisions and / or will schedule infrastructure investment years too early or too late. Women are the focus of this paper. In recent decades women have accounted for much of the growth in hours travelled, in public transport patronage and in vehicle kilometres travelled. For the purpose of this paper, busy women are considered to be highly-skilled professionals in paid work who also care for dependents (double-shift). They tend to exhibit many of the behavioural patterns of workaholics. This paper sets out a model developed by Cavagnoli to help transport professionals move away from stated preference surveys of the value of time based on tiny sample sizes, towards revealed preferences of hundreds of millions of trips captured by large scale statistical tools, including the emerging time use database for Melbourne produced by Ironmonger.
