| Abstract: | In this paper, a new car-following model is presented, taking into account the anticipation of potential lane changing by
the leading vehicle. The stability condition of the model is obtained by using the linear stability theory. The modified Korteweg–de
Vries (KdV) equation is constructed and solved, and three types of traffic flow in the headway-sensitivity space, namely stable,
metastable and unstable ones, are classified. Both the analytical and simulation results show that anxiety about lane changing
does indeed have an influence on driving behavior and that a consideration of lane changing probability in the car-following
model could stabilize traffic flows. The quantitative relationship between stability improvement and lane changing probability
is also investigated.
