Reprint of Measuring trends in household expenditures for daily mobility. The case in Lyon, France, between 1995 and 2015

International audienceThere are very few suitable databases for an in-depth analysis of changes in the expenditures of households for their daily mobility, despite the fact that the increase in fuel costs in the years following 2000 raised questions concerning the vulnerability of certain households in light of their dependence on cars. This article uses three consecutive surveys on household transportation carried out in the Lyon urban area in France in 1995, 2006 and 2015. We propose a technique to extract consistent data on household expenses from the three surveys. Changes are then analysed, taking care to distinguish between changes in prices, population structure and mobility behaviour. The results reveal trends that diverge widely during the two periods between the surveys. In addition, significant differences appear in the changes in expenditure levels and structure depending on the location of households. Finally, a transition to reduced car use has become very clear, however significant generational effects produce contrasting results in young and retired households
