La mobilité active et durable : quand la psychologie et la géographie se combinent pour mieux la comprendre et la promouvoir

Abstract : The car is the most widely used mode of transportation for daily travel (63% of daily trips in France are made by car). Nevertheless, frequent car use is a major source of physical inactivity and is associated with a major emission of air pollutants and greenhouse gases. Conversely, the daily use of active and sustainable mobility (cycling, walking, using public transport and carpooling) is associated with greater physical activity, lower air pollutant emissions and a smaller carbon footprint. For these reasons, a variety of measures have implemented to reduce car use and increase the use of active and sustainable mobility: hard levers targeting changes in the geographical and economic context of individuals and soft levers targeting changes in mainly psychological factors such as intention or attitude towards active mobility. The implementation of these measures requires an in-depth knowledge of the factors influencing active and sustainable mobility. However, only a few studies seem to have mobilized more than one disciplinary framework to study mobility. Moreover, the levers implemented in the past have methodological and theoretical limitations: few studies have mobilized robust methodological frameworks, few studies have followed the change in mobility beyond six months of the study, few studies have mentioned the theories mobilized when choosing the levers. The central question of this doctoral thesis was to better understand the factors associated with active and sustainable mobility in order to propose a study protocol for changing mobility behaviors (towards more active and sustainable mobility) based on scientific theories. For this purpose, this thesis has combined psychological and geographical approaches and a diversity of methodologies (surveys, individual interviews, focus groups, a pilot study). The main results of this doctoral work indicate that (a) active and sustainable mobility is independently associated with geographical, socio-demographic and psychological factors, (b) the association between some geographical and socio-demographic factors and active and sustainable mobility can be moderated by some psychological factors, (c) the study targeting mobility change (a randomized controlled trial offering six months of transportation access, personalized mobility counseling, and motivational techniques such as goal setting and action plan development) is feasible and shows an important degree of fidelity when it is implemented in the field, (d) the training offered to the implementation team appears to be effective in increasing their self-efficacy towards study implementation and their knowledge in the field of mobility and air pollution. The results of this doctoral work highlight the need to combine interdisciplinary approaches in order to better understand and promote active and sustainable mobility.
