Traffic road modeling based on energetic approach

This work offers the macroscopic modeling of traffic road based on the Bond Graph (BG) paradigm for using these models in the traffic road control. We recall to the first time, the various models of the traffic road. Then we describe the Bond Graph with these principles in order to model three various macroscopic traffic flow models with Bond Graph. The originality of our approach lies in the fact that the road traffic can be modeled perfectly with Bond Graph and make use in the traffic control such as: ramp metering, crossroads, etc. Simulations of the developed traffic flow models are carried out in order to reproduce the famous fundamental diagrams (flow-density and speed-flow). Finally we have the results before opening prospects for future work.
