This paper introduces a new two-lane high-order continuum model
by embedding the two delay time scales continuum traffic model presented by
Xue (2003 Phys. Rev. E 68 066123) into the multi-lane model proposed
by Daganzo (1997 Transpn. Res. B 31 83) with the consideration of
the coupling effect between the vehicles of two lanes in
instantaneous traffic situation and lane-change effect. In the novel model,
the coupling effect of two lanes and phenomena of lane change, which were
not discussed in Daganzo's model and Xue's model, are taken into account.
Numerical simulation shows that it is in accordance with real traffic flow.
This obviously indicates that the new phenomenon and behaviour are analogous
results as single lane presented by Xue, and the proposed model is more reasonable on
two lanes. Furthermore, the generation rate between two lanes is also
investigated. The results show that the formation and diffusion of traffic
shock wave can be better simulated on two lanes. 相似文献
