An energy concept for macroscopic traffic flow modelling

The main differences between the deterministic macroscopic models are to be found in pressure expressions and representation of various phases observed experimentally. In this paper, using the laws of fluid dynamics and thermodynamics to describe the traffic flow reality, a new expression of pressure is made and a second order model is proposed. It represents different traffic flow phases and, thus, conditions for transition between phases become clear. In addition, this approach suggests solutions to a number of problems yet to be resolved. Afterwards, simulations are presented which show some agreement with experimental data. Finally, the proposed model highlights different types of possible actions for traffic flow control.
