巴黎—里昂间是法国交通最繁忙的地区,过去15年间这个地区客运量平均每年增长4.2％,货运量平均每年增长4％。尤其是地中海沿岸福奥斯工业区正在大规模开发,预测从巴黎向马赛方面的运量到1980年对既有线路言无论如何也不会不达到饱和。这样一来,在制定第六次社会经济发展计划时作为其中一环是想到了巴黎—里昂新干线。 Paris - Lyon is the busiest area for traffic in France, with passenger traffic in the region growing at an average annual rate of 4.2% over the past 15 years, with an average annual increase of 4% in volume. In particular, the Fuorisi industrial zone on the Mediterranean coast is undergoing large-scale development and the volume of traffic from Paris to Marseille is forecasted to not be saturated by 1980 at the existing routes. As a result, the Paris-Lyon Shinkansen was thought of as part of the sixth socio-economic development plan.
