I can't help but translate an extract of a recent article read in the French newspaper "Le Monde". This paper was about the Line 13, famous for being the toughest of the entire Paris metro network. The discussion is about planning capacity:
Filling pipes. The calculation would it be presumptuous? The pipes are filled faster than people ever imagine. In practice, whenever a transport line is installed or extended, traffic forecasts are revised upwards within six months. And it applies to highways, too. The director of the Line 13 is also well placed to know it: "the mayors of cities served by the line bring new enterprises; they announce 5,000 jobs over here, 10,000 there. Development of this policy, I 'm not sure it is a good thing" he laments. Because, incredible as it may seem, when creating new offices close to the line, the RATP(*) is neither informed nor consulted.
Doesn't it sound familiar?
* RATP is the organization in charge of designing and running the Paris metro.
