Macroscopic modelling of traffic flow on the Boulevard Périphérique in Paris

Three macroscopic mathematical models are presented and compared on the basis of real traffic data collected from the Boulevard Périphérique in Paris. All models include the conservation equation and a nonlinear, static, or dynamic volume-density relationship. Parameter estimation is effectuated for each model so as to reflect the characteristics of the particular application case considered. Sensitivity investigations for changed application conditions are included.
