Friedrichs scheme for the fluid dynamic traffic flow model was also presented 6 7 a computational study of the non scaled multilane traffic flow model was presented 9 in this research article we choose a numerical scheme named explicit upwind difference scheme to compute the numerical solution of the two lane traffic flow model as an ibvp. 7 single lane versus two lanes a detailed comparison of the single lane model with the corresponding two lane model with effects of parameters and is shown in figure 3the graph shows rise in maximum flow when simulating two lane traffic as compared to one lane systemthis is due to the fact that some vehicles move into the other lane to avoid traffic jam and continuously contribute to flow. Citeseerx document details isaac councill lee giles pradeep teregowda abstract in this work a numerical solution of a dimensionless form of the macroscopic two lane traffic flow model based on a linear density velocity relationship is studied we make the two lane traffic flow model dimensionless by introducing some dimensionless parameters. As per our numerical test ssat model outperforms vissim and transmodeler which are two widely used simulation software at the macroscopic level besides overtaking distance ratio and trajectory distribution replicate the evidence of the highly mixed traffic flow in addition the case study is also satisfactory. It is shown that the self stabilization effect can increase traffic stability on two lanes whether lane changing occurs or not according to linear stability analysis in view of numerical simulation the self stabilization effect enhances the stability of the traffic flow in the modified lattice hydrodynamic model for two lane freeway
