The Greater Paris Metro Project: Characteristics and Challenges

International Transport Forum

In this brief introduction, the author will highlight the two important characteristics of our project and our overall challenge of carrying out a robust assessment of its socio-economic impact, and then he will ask four questions which seem to him to be fundamental.
