The effects of lane changing on the characteristics of traffic flow have not been investigated sufficiently. In this paper, we use a driving model based on finite-state-machine to investigate the effects of lane changing on macroscopic characteristics of traffic flow. In homogenous traffic, the effects of lane changing are not significant. However, in heterogeneous traffic composed of vehicles with different maximum speed, the flux in the low to middle density increase if lane changing is permitted. Furthermore, in heterogeneous traffic where vehicles only have difference in normal acceleration, lane changing can't increase the flux significantly. In conclusion, the effects of lane changing on traffic are tightly related to both the difference of vehicles and the density of traffic.
