Study on Synchronized Traffic Flow from the Energy Dissipation

In this paper, the synchronized flow in the mixed traffic flow is investigated under the periodical boundary condition by using the braking light (BL) model from the perspective of energy dissipation. The relation of the flow rate and the energy dissipation with the different maximum velocity, different length of vehicle and the ratio of the mixed traffic flow (cn) is simulated and analyzed. Numerical results show that the phenomenon of synchronized flow occurs when the maximum velocity reaches a certain value, the energy dissipation also have an interesting phenomenon at the state of the synchronized flow . The maximum velocity vmax, length of vehicle LL(the long vehicle), Ls(the short vehicle) and the ratio cnof the mixed vehicles have a great impact on the synchronized flow. The energy dissipation-occupancy rate C and its corresponding fundamental diagrams are obtained.
