dc.description.abstract In this work, we have investigated in sufficient detail the traffic flow behavior under open boundary conditions by using a new injection strategy. For that purpose, we have taken into account different traffic flow situations and drivers parameters. In this context, we have considered the deterministic and the non deterministic rules of vehicular motion by using the cellular automata model, that is, under the fundamental diagram approach and the three phase theory. Furthermore, we have investigated two important features of traffic flow, namely, the presence of moving defects (the slow vehicles) as a result the heterogeneous traffic flow composition and spatial defects which induce the drivers to interact laterally. It is found that the phase diagram can be constructed by neglecting the bulk term and considering only the inflow and the outflow functions, that is, for the deterministic and the non deterministic cases. Surprisingly, this finding is valid even in the presence of moving defects (the impurities). Hence, the platoons' appearance in the system's bulk can be discarded for any fraction of the moving defects. However, in the presence of spatial defects, the inflow and outflow functions could determine the phase diagram in two cases: a compact distribution of defects or a random distribution of defects associated with a weak velocity correlation between the vehicles. Otherwise, the bulk term should be considered. The analytical expression of the inflow function can be obtained by performing a mean-field approximation for the expected stationary particle density by considering only the system's beginning. Finally, in addition to the importance of those studies in understanding the one dimensional systems that are driven far from equilibrium, they have tremendous applications in the practical framework. Indeed, our studies may help traffic engineers to predict the traffic flow states in the presence of the previously mentioned situations, flow optimization and performing low cost measurements. fr_FR
