Modeling of traffic flow within a given urban area. This first approach, also called the "bathtub model", is based on the Macroscopic Fundamental Diagram (Outflow-MFD) which relates the vehicle exit rate to the accumulation inside the zone (number of circulating vehicles). We also denote it the "accumulation-based" approach.

Situation 1 : free-flow conditions for the whole urban area

Situation 2 : congested conditions due to a restriction on the outflow


This second representation concentrates more particularly on the distance that the vehicles have to travel in the area. It is based on the Macroscopic Fundamental Diagram (Speed-MFD) which relates the global mean speed to the accumulation inside the zone. We also call it the "trip-based" approach.

Situation 1 : free-flow conditions for the whole urban area

Situation 2 : congested conditions due to a restriction on the outflow


Example of a simulation on the network of Lyon 6th district with several zones. Traffic conditions are considered homogeneous in each zone. Traffic flow is described by the first above-mentioned modeling approach. The demand scenario creates flows from North to South that interact with flows from East to West.

Lyon 6 network split into 8 zones:

Lyon6 Lyon6

Simulation results: evolution of the mean speed and the number of vehicles in each zone.


Another example of simulation on the network of Lyon-Villeurbanne (France). The demand scenario corresponds to a typical weekday.
