Automobile dependency in Algiers, between efficiency of the automotive system and precariousness of the transport system

As a result of half a century of transformations due to successive urban policies, Algiers today is a spread, fragmented and disjointed agglomeration. It also faces real challenges in terms of planning of transport and mobility. The automobile dependency status is reflected by the fact that it has become essential for daily movements for a large part of the population. The organization and efficiency of the transport system and urban form directly influences the mode of transport favored by the population. Our article proposes to compare the performance of private automotive system and public transport in terms of accessibility. Through the establishment of a GIS database and a comparative approach, the result of this work allowed us to better understand the space-time dimension in Algiers and the evolution of accessibility, that have happened to the various agglomerations between 2004 and 2015. Indeed, this approach has never been the subject of a deep analysis in the various researches on the city of Algiers. An accessibility modeling appears to be a very interesting approach, firstly to have a clear vision of “accessibility”, one of the decisive parameters of any transport policy and also to better appreciate the consequences of the various public transport policies.
