Implementing a two-step decision-aid tool for the assessment of new mobility offers in a spatial framework

In this article we seek to elaborate various sustainable mobility scenarios depending on heterogeneous
geographical contexts. We use a multicriteria decision analysis (MCDA) to assess 50 mobility offers, relying on
an original two-step assessment method. In a first step, we use the diviz decision-aid tool to obtain a global score
for every offer, on the basis of 18 criteria that cover the three domains of sustainable development: economics,
environment, society. In a second step, we use the MICMAC decision-aid tool to build relationships of influence
and dependency between the 18 criteria. For each type of territory, we state what could be a development scenario
for the future of mobility. Ultimately, an innovative hybrid mobility solution relies on the strengths and levers of
the offers that were assessed, in response to the mobility scenario. We identify relevant solutions for dense and
low-dense areas: in particular, carpooling offers reach particular efficiency in low-dense areas, combined with
walking practices. Such combinations should be assisted by reliable multimodal mobility applications.
