La congestion du boulevard périphérique parisien : Estimations, évolution 2000-2007, discussions
This research focus on the congestion cost of the Parisian ring-road. We mobilize a speed-density relation which enables us to differentiate the costs of the road's use and its congestion according to speed-classes of 5 km/h. We lead this work at three analytical scales thanks to a large database : the Parisian ring-road considered on its whole, according to the different daily periods and the geographical sub-sections of the infrastructure. The economic cost induced by the over-use of the Parisian ring-road reaches 130 M € in 2007. The social losses have known a 10 % increase since 2000 (120 M €), mainly because of the speed's retreat (-5 %) and a higher opportunity cost of the time (+8 %). We finish this work by offering a possible pricing scheme for the Parisian ring-road.
