La mobilité urbaine et la planification des réseaux de transport dans un contexte de projet de renouvellement urbain : cas d’Alger

Abstract

The issue of urban sprawl is at the heart of the debate on challenges facing cities in the 21st century. Cities are growing, expanding and spreading worldwide. Urban sprawl continues to attract the interest of several research projects that highlight the evolution of mobility is at the heart of the spatial growth process of cities. Increasing car ownership, the evolution of modes of transport, increasing of the travelling speed… are important factors explaining the process of urban growth. Indeed, with the evolution of the travelling speed, the notion of proximity has lost its physical dimension in favor of a more temporal dimension. The modes of mobility are changing the urban forms that, in turn, affect commuting practices. Addressing the issue of urban renewal as a response to the problems of urban sprawl requires a deep reflection, on the one hand, on the problems of daily mobility, including the extensive use of the automobile, and on the other hand, better control of the determinants of sustainable urban mobility. In this context, this thesis intends to demonstrate the usefulness of urban renewal policies as effective strategy to influence urban morphology and therefore result in regulation of daily mobility. The main objective is the development of the factors generating a daily mobility less automobile dependent. The challenge is to direct the urban renewal policies to the implementation of effective strategy that can promote sustainable mobility and control sprawl. It is a question of scoping our political choices to multiple tracks, such as densification, urban diversity, speed-control, etc ... able to enter Algiers city in sustainability. Algiers is a suitable framework for the empirical study of the relationship between urban form and daily mobility. The urban space of Algiers is representative of various morphological changes, high residential mobility, disturbing urban sprawl, remarkable evolution of transport infrastructure and increasing of mobility. All of these variables, assures us of a field study adapted to our problem.
