What is it about?
The delayed-time effect may contribute to improving traffic flow. Then, a new lattice model in this paper is constructed with the consideration of the delayed-time effect of traffic flux for two-lane freeway. The linear stability condition can be acquired by applying linear theory. Moreover, numerical simulation shows that the delayed-time effect of traffic flux contributes to the stability of the traffic flow in the lattice model of two-lane traffic flow.

Why is it important?
The delayed-time effect of traffic flux from the leading lattice’s historic flux has not been studied in case of lane change in the existing lattice models of two-lane traffic flow. Therefore, to explore the influence of the delayed-time effect of traffic flux on two lanes, a new two-lane lattice model will be proposed with the delayed-time effect of traffic flux term in the following section.
Perspectives
The delayed-time effect of traffic flux plays an important role on traffic stability on two-lane highway. To reveal the delayed-time effect, the linear stability condition is deduced in two-lane lattice model, which shows that the delayed-time effect can increase the stable region of space. Moreover, numerical simulation shows that the traffic stability is improved by considering the delayed-time effect for two-lane freeway under lane changing. And the traffic stability is continuously strengthened with the increase of the delayed-time effect in two-lane system, which implies that the delayed-time effect contributes to restrain traffic jam in two-lane lattice model.
