Politique de transports et accès à la ville pour tous ? Une méthode d'évaluation appliquée à l'agglomération lyonnaise

Abstract : Assessment tools, used in France to inform decision makers on urban transport policies, do not fully integrate the social dimension of these policies. However, this issue is becoming paramount. By using the Amartya Sen theoretical approach, our PHD aim is to build an evaluation method allowing to give an account of this dimension, in terms of equal opportunity of access to the social reproduction activities. With this intention, we have built a tool that could identify, at the infra-communal level, the social groups and the rich or poor districts of an urban area. We have built a basket of goods accessibility indicator. This indicator evaluates, for a given travel mode, for each service of the basket of goods and from a residence, the necessary maximum time to access the number of activities for 1.000 inhabitants. This indicator takes into account the different subsystems of an urban area.

The method is applied on the Lyons conurbation. First of all, we show the existence of chances inequality between the individuals and between the districts to the basket of goods access, for the year 1999. These inequalities are born mainly from unequal access to the car (three times more powerful than public transport in terms of access time to the basket of goods), but also from the heterogeneous distribution of the activities and quality of the public transport supply. The changing in the activity localisation between 1990 and 1999 highlights an aggravation of the access inequalities between the poor districts and the rich districts. It seems as if the richest populations shaped the functional division of the urban space and the activity localisation, to the detriment of underprivileged populations. Finally, we show that a strong improvement in the public transport supply has limited impacts that often have difficulty compensating for the losses of accessibility due to the changing of activity localisation.
