The aim of this paper is to better identify the decisive factors of the daily mobility by bus in urban areas. We try in particular to study to what extent the quality of the transportation supply by bus determines its use. In a first step we develop an indicator which describes locally the quality of the transportation supply by bus. In a...

The metric of the current roads networks tends intrinsically to favour the efficiency of the routes which have the longer range, what leads to promote urban sprawl and automobile dependence. Indeed this metric ensures to individuals the possibility to travel even further, without necessarily increasing their transportation time in the same...
The automobile accessibility produced by the roads networks tends intrinsically to favour the efficiency of the routes which have the longer range, what leads them to promote urban sprawl and automobile dependence. According to this assessment, we aim to introduce the "slow networks" concept, which have an opposite metric. Here, the longer the...
In this article, the city is defined as a potential of interactions, as a capacity to reach people. This potential certainly depends on the population density but also on the transportation capacities. That is why we are proposing a functional examination (and not a morphological one) of urban and periurban areas through the calculation of the...

For 30 years, changes in the urban form (urban sprawl allowed by the massive use of automobile) and changes in the urban functionning (emergence of new rhythms more individual) have caused strong inequalities in the accessibility to urban facilities. First we give some examples of these inequalities in the case of space-time accessibility to...

The fragmentation of the urban patterns is actually a largely discussed topic in urban planning. In particular the consumption of space and the traffic flows generated are considered as most negative impacts of this development. However, for many reasons it doesn't seem possible to find simple solutions to manage this evolution. The mobility...

Our contribution involves the transport modelling. It aims to identify and to illustrate what are the available levers to provide coherent and massive flows, which are favorable to public transportation supply and more precisely to Demand Responsive Transport systems. Three main levers are discussed : - the first one involves the urban...

Pour limiter la consommation d'espaces périphériques par l'étalement urbain et contrer ses effets négatifs, la densification de l'urbanisation existante est souvent préconisée, sans toutefois faire l'objet d'un consensus général, puisque les formes denses présentent elles aussi des effets induits négatifs. En pratique, la densification des...

General access to automobile speed has enabled the separation between the places of life, in particular between the house and the place of work. In return, people are now addicted to this speed. Without speed, it is often impossible to perform the everyday life within the limits of a fixed travel-time. With the beginning of a stagnation or even...
